ADOPTION OF IMPROVED MAIZE VARIETIES IN KIREMU DISTRICT, OROMIA REGIONAL STATE, ETHIOPIA
ABSTRACT
Improving agricultural productivity and development and thereby improving smallholder farmers’ income requires increased efforts in influencing farmer to use yield enhancing technologies like improved maize varieties. It is from this ground the need to analyze the factors that influence the adoption and intensity of use of improved maize varieties. Two - stage sampling procedure was employed to select the target households. In the first stage, out of 19 kebeles in Kiremu district three kebeles were selected using simple random sampling. Secondly, stratified random sampling method was employed to identify sample households. Finally, sample of adopters and non-adopters were selected by using simple random sampling. Structured instrumental questionnaire was developed, pre-tested and used for collecting data from 189 randomly selected households. Descriptive statistic and double hurdle model were employed to analyze data. Results of descriptive analysis showed that there were statistically significant differences between adopter and non- adopter households with family size, education, and distance to market, number of oxen, farm income, livestock owned and frequency of extension contact. Similarly, Double hurdle model results showed that improved maize varieties adoption decision of farm households has positively and significantly determined by education, family size, farm income, livestock owned, number of oxen and frequency of extension contact and intensity of use of adoption of improved maize varieties also positively and significantly determined by education, farm income, number of oxen, membership of farmers’ cooperative union and livestock owned. It is therefore recommended that government and other development organization should create a favorable environment like strengthening farmers’ knowledge on modern agriculture production throughout strengthening of the extension services, creating awareness on the advantage of being the membership of farmers’ cooperatives union and giving more attention to farmers’ priorities and needs related to agriculture.

1. INTRODUCTION
1.1. Back ground of the Study
As the world’s population is expected to reach 9.1 billion by 2050, the production of food, mainly staple crops is expected to increase accordingly, especially for the 870 million people who are currently food insecure (IFC, 2013). This suggests that the dominant role of agriculture as the primary source of food and employment creation in the developing economies should be stepped up. A study by Alexandratos and Bruinsma (2012) indicated that agricultural production needs an increase of 60% by 2050 to meet the world’s consumption demand. This expected growth means that smallholder farmers who are the principal agent of agricultural production have a significant role to play. In Sub-Saharan Africa (SSA), a majority of the population is agriculture dependent with about 55% in the rural areas (IFC, 2013).
Among the countries from this region, Ethiopia remains to be one of the poorest countries in the world and nearly 30% of households in the country are in extreme poverty (IFC, 2013). More than 30% of the population is undernourished and prevalence of food inadequacy is 41.3% (FAO, 2015). Thirty-six percent of Ethiopian farming households are engaged in subsistence farming, living on less than two USD per day (MoA& ATA, 2014).
Therefore the ultimate goal of any rural or farming development strategy or program is to improve the welfare of rural households. This goal is achieved among other things by increasing productivity at farm level and by raising farmer’s income and by improving their welfare. This is possible if and only if improved agriculturaltechnologies are properly transferred and disseminated to farmers so as to deepen and intensify their production. Institutions that are involved in generating agricultural technology need to have the capacity to carry out studies that document the process of adoption and help in explaining the rationale for framer’s decisions (Assefa and Gezahegn, 2009). Also, improving the agricultural production and productivity in the country is not a matter of choice. Enhancing rural households‟ income and food security through improving access to improved agricultural technologies is a key development strategy in Ethiopia. Consequently, successive governments of Ethiopia have taken a keen interest in establishing, supporting and nurturing a dynamic national agricultural research system (NARS) capable of adapting and developing improved agricultural technologies suited to the diverse agro-ecologies and
1
socio-economic conditions of the country. Over the years, in response to the political and socio-economic dynamics of the country, the NARS and the Agricultural Extension System (AES) have evolved in several respects including organizational structure, agro- ecological coverage, mandate as well as research and extension approaches followed. Currently, agricultural research in Ethiopia is based on a decentralized system of a network of institutions involving the Ethiopian Institute of Agricultural Research (EIAR), Regional Agricultural Research Institutes and Higher Learning Institutions. While the primary focus of NARS remained on agricultural technology adaptation and generation, it has also been involved in technology dissemination efforts, although with limited scale, with the intent of creating technology demand. Agricultural extension efforts pioneered by the research system include the package testing program of the Institute of Agricultural Research (IAR) in the 1980’s, Pre-extension Demonstration and Popularization activities in the 1990’s and early 2000’s and the current agricultural technology pre-scaling up efforts run by the federal and regional agricultural research institutes (Kibebew et al., 2011).
The most important cereal crops cultivated in the country are teff (3,017,914.36ha), maize (2,135,571.85ha), sorghum (1,881,970.73ha), wheat (1,696,082.59ha), and barley (959,273.36ha) (CSA, 2017). Although agriculture is the foundation of the country’s economy, crop productivity has remained low. For instance, the average national yield of important food crops such as teff, maize, sorghum ,wheat and barley were 16.64 , 36.75 , 25.25,26.75 and 21.11 Quantity per hectare respectively (CSA, 2017) while the potential of those crops is ten to eleven times higher than (MoARD, 2008). Food insecurity has been an importunate issue in the country where the recurrent drought considerably affects crop production of its numerous villages (Dercon et al., 2005).
According to Abate et al., (2015) furthermore, the Ethiopian seed market has been dominated by BH660 and BH540; the average of 80 % of the currently grown varieties is more than 20 years. There are also hybrids that came into production between 2005 and 2008, but their amounts remain limited, with the exception of the Pioneer hybrids Shone and Agar.
Defining rate of adoption as the proportion of households using freshly purchased (un- recycled) improved maize varieties, the DIVA study indicated about 31% of the farmers planted improved varieties (De Groot et.al, 2014).The same study indicated, of the improved maize varieties promoted, BH660 was grown by 27% of households on about
2
21% of the maize area while BH540 was grown by about 6% of the farmers on about 9% of the maize area during the same season. Other less popular maize varieties among sample farmers include BH543, BHQP542, Morka, Melkassa-1, Melkassa-4, and AMH800. A study by Chilot et al (2016b) designed at tracking maize varietal adoption comparing deoxyribonucleic acid finger printing techniques with household surveys revealed interesting results. While farmer responses suggest that 55.9% of the respondent used improved maize varieties during 2013 production season, the Deoxyribonucleic acid fingerprinting indicated 61.4% of the respondents to have actually used improved maize varieties with a difference of 5.5 percentage points suggesting household survey based adoption estimates under estimate adoption levels. The similar study further revealed that only 30% of the farmers know the variety they cultivated by name. When considering only adopters, the proportion of famers who identified the variety they grew by name increased to about 49%. Farmer knowledge of cultivars, however, are restricted to only four hybrid maize varieties, namely, BH-660, BH-540, BH-140 and Shone.
Generally, From Oromia region Kiremu district is potential producers of Maize and no study was conducted on adoption and intensity of use of improved maize varieties and farmers’ perception regarding of improved maize varieties characteristics on local variety previously in this areas. This study therefore conducted to examine the determinants of adoption and intensity of use of improved maize varieties with a purpose of generating information that help understand and evaluate the key challenges to the adoption of improved maize in the study areas which will enhance informed decision making to improve adoption of maize, their production and productivity by increasing land allocated for improved maize varieties in the study areas.

1.2.Statement of the problem
Improved highland Maize is a new and promising crop gradually becoming important in the highlands of Ethiopia. Its production is rapidly increasing in the highland parts of the country where it has been a minor crop in the past (Milkias and Abdulahi, 2018).In spite of the widespread technology generation and dissemination efforts, yields of major crops such as wheat, maize and teff are still low averaging 2.45 ton/ha, 3.25 ton/ha, and 1.47 ton/ha, respectively, suggesting the country has not fully taped the benefits of the investments made on agricultural technology generation and dissemination efforts (CSA,2014). According to Dawit et al. (2010), one of the main reasons for seed waste in either public or private seed stocks during high demand has been associated with the limited efficiency of targeting seed production and distribution in Ethiopia. It is also believed that some superior cultivars that have been released might not have been adopted because of lack of sufficient considerations of farmers’ preferences in their development process (Derera et al., 2006). According to Alene et al., (2000) Ethiopia also faced severe food shortages within the past two decades and is on constant threat of famine. One major reason for the low agricultural productivity in Ethiopia is the low rates of adoption of improved agricultural production technologies. According to Twumasi-Afriyie et al., (2002) high land maize is one of the major food crops where research brought tangible improvement in production and productivity. However, in sub-humid agro-ecology, smallholder farmers’ knowledge and use of agriculturaltechnologies in general and improved highland maize varieties in particular, are limited.
Smallholder farmers’ knowledge and use of agricultural technologies in general and improved maize varieties in particular, are restricted due to various factors that are either internal or external to the farmers’ circumstances. Most commonly studied internal factors that affect adoption and use of agricultural technologies are farmers’ attitude towards risk, household characteristics that affects the level of production and consumption, resource endowments, etc. External factors could be access to technologies, in particular through a well-developed seed system (Croppenstedt et al., 2003; Alemu et al., 2008; Asfaw et al., 2011), infrastructure, institutions (Beke, 2011), markets, and enabling policy environments (Smale et al., 2011).

The low crop productivity in one hand and availability of proven improved agricultural technologies that would increase productivity by a significant margin as well as the extensive extension efforts to get farmers adopt improved agricultural technologies on the other hand has trigger interest in crop technology adoption and analysis of factors that influence the adoption decision behavior of smallholder farmers in the country (Chilot and Dawit, 2016).
Regardless of the intervention of improved maize varieties widely undertaken in the district, the factor affecting adoption and intensity of use of improved maize varieties and the perception of smallholder farmers about the characteristics of improved maize varieties were not well identified. In the study area, there was no empirical information so far on the adoption of improved maize varieties and the perception smallholder farmers’ about the characteristics of improved maize varieties on local maize variety.
Therefore, improving agricultural productivity and development and thereby improving smallholder farmers’ income requires increased efforts in influencing farmer to use yield enhancing technologies like improved maize varieties. It is from this ground the need to determine the factors that influence the adoption and intensity of use of improved maize varieties in kiremu district study area seen as a thoughtful gap that must be bridged if the problem of limited improved maize varieties adoption among farmers is to be addressed to be improved.
1.3. Research Question What are the factors affecting the adoption of improved maize varieties to the study area? What are the factors affecting the intensity of use of improved maize varieties to the study area? What are the farmers’ perceptions regarding to improved maize varieties on local seed to the study area?
1.4. Objectives of the Study
1.4.1. General objective
The main objective of this study is to analyze the Adoption of Improved Maize Varieties in Kiremu District.
5
1.4.2. Specific objectives
To identify the factors affecting adoption of improved maize varieties in the study area. To identify the factors affecting the intensity of use of improved maize varieties in the study area. To identify Perception of farmers towards improved maize varieties attributes on local maize seed in the study area.
1.5. Significance of the Study
There are several reasons to invest in studying the adoption of agricultural technologies. These include improving the efficiency of technology generation, assessing the effectiveness of technology transfer, understanding the role of policy in the adoption of new technology, and demonstrating the impact of investing in technology generation. All development partners like technology generators, technical assistants, extension agents, policy makers, NGOs and development agents involved in agricultural development must be aware and understand the factors affecting the adoption and intensity of improved maize varieties. Policy makers will benefit from the research output since they require micro level information to formulate and revise policies and strategies. This could make easy allocation of major resources for research, extension and development programs.
1.6. Scope of the Study
The study covers only Kiremu district Oromia region. The data used for this study is based on a farm-household survey. Besides, the study paying attention on the application of double hurdle model to assess the adoption and intensity of use of improved maize varieties.
1.7. Limitation of the Study A range of studies are aimed at establishing factors underlying adoption and intensity of use improved maize varieties. As such, there is an extensive body of literature on the economic theory of technology adoption. Several factors have been found to affect technological adoption. These include government policies, technological change, market forces, environmental concerns, demographic factors, institutional factors and delivery mechanism. However, the study is concerned only with socioeconomic factors, demographic factors and institutional factors to assess factors that affect farmer’s decisions 6
to adopt improved maize varieties and to assess factors that affect intensity of use of improved maize varieties and also the perception of farmers towards improved maize varieties on local maize variety. This is mainly because of the limited resource available to the study on a wider scale.
1.8. Organization of the Thesis
This study is organized into five chapters. The first chapter outlined introduction, statement of the problem, research questions, objectives, significance and, scope and limitations of the study. Concepts and definition used in the present study along with a review of the past works are discussed in chapter two. Chapter three describes the study area and research methodology applied.

2. LITERATURE REVIEW
The literature review encompasses the conceptual definitions /theoretical descriptions and empirical evidences related to adoption of agricultural technologies, farmers’ decision making behavior in adoption of improved crop varieties, overview of maize varieties and production in Ethiopia and tracking diffusion of improved agricultural technologies has been reviewed and also encompasses the conceptual frame work of the study.
2.1. Definitions and Concepts The adoption of a production technology is not a unit and instant act; it consists of several stages and involves sequence of thoughts and decisions. According to Youngseek and Crowston (2011) adoption is a process consists of three stages namely pre- adoption, adoption and post- adoption. At the pre-adoption stage, people may examine a new technology and consider adopting it. At the adoption stage, they form an intention to adopt the technology, and they eventually purchase and use it. At the post-adoption stage, people can either continue or discontinue using the technology. It is well recognized that improvement in agricultural productivity among farmers is achieved through improved agricultural technologies (Moshi, 1997).
The Adoption process is the change that takes place within individuals with regard to an innovation from the moment that they first become aware of the innovation to the final decision to either use it or not. Also, as it is emphasized by Ray (2001) adoption does not necessarily follow the suggested stages from awareness to adoption; trial may not always be practiced by farmers to adopt new technology, they may adopt the new technology by passing the trial stage. The adoption pattern for a technological change in agriculture is a comprehensive process. A large number of personal, situational and social characteristics of farmers have been found to be related to their adoption rate.
Dissemination of innovation theory: Dissemination of innovation theory by Rogers (2003) is the theory guiding this cram. According to Medlin, (2001) DIT is the most appropriate for investigating the adoption of technology in higher education and educational environments. Actually Rogers (2003) used the word innovation and technology as synonyms. He defined technology as a design for instrumental action that reduces the uncertainty in the cause-effect relationships involved in achieving a desired
8
outcome. Adoption as the decision of full use of an innovation as the best course of action available where as rejection is a decision not to adopt an innovation and diffusion is the process in which an innovation is communicated through certain channels over time among the members of a social system. As expressed in the definition of diffusion, innovation, communication channels, time, and social system are the four key components of the diffusion of innovations. The most important objective of this theory is to understand the adoption of innovation in terms of four elements, including innovation, communication channels, time and social systems and five stages, including knowledge stage, persuasion stage, decision stage, implementation stage and confirmation stage.
Innovation: Rogers describe innovation as an idea, practice, or project that is perceived as new by an individual or other unit of adoption. It may have been invented a long time ago, but if individuals perceive it as new, then it may still be an innovation for them. The newness characteristic of an innovation is more related to the three steps, namely knowledge, persuasion, and decision of the innovation-decision process. According to Rogers (2003) uncertainty is an important obstacle to the adoption of innovations. An innovation’s consequences may create uncertainty, whereas consequences are the changes that occur in an individual or a social system as a result of the adoption or rejection of an innovation. To reduce the uncertainty of adopting the innovation, individuals should be informed about its advantages and disadvantages to make them aware of all its consequences.
Communication channels: The second element of the diffusion of the innovation process is communication channels. For Rogers (2003) communication is a method in which participants create and share information with one another in order to reach a mutual understanding. This communication occurs through channels between sources. Besides Rogers defines source is an individual or an institution that originates a message and the channel is the means by which a message gets from the source to the receiver. In addition Rogers states that diffusion is a specific kind of communication and includes these communication elements: an innovation, two individuals or other units of adoption, and a communication channel. Mass media and interpersonal communication are two communication channels. While mass media channels include a mass medium such as TV, radio, and newspaper, interpersonal channels consists of a two-way communication between two or more individuals. On the other hand, diffusion is a very social process that
9
involves interpersonal communication relationships. Thus, interpersonal channels are more powerful to create or change strong attitudes held by an individual. In interpersonal channels, the communication may have a characteristic of homophiles, that is, the level to which two or more individuals who interact are similar in certain attributes, such as beliefs, education, socioeconomic status, and the like, but the diffusion of innovation requires at least some degree of heterophony, which is the degree to which two or more individuals who interact are different in certain attributes. In fact, one of the most distinctive problems in the diffusion of innovations is that the participants are usually quite heterophilous.
Time: According to Rogers (2003) the time aspect is unnoticed in most behavioral research. He argues that including the time dimension in diffusion research illustrates one of its strengths. The innovation-diffusion process, adopter categorization, and rate of adoptions all include a time dimension.
Social System: The social system is the last element in the diffusion process. Rogers (2003) defined the social system as a set of consistent units engaged in joint problem solving to accomplish a common goal. Since diffusion of innovations takes place in the social system, it is influenced by the social structure of the social system. For Rogers (2003) structure is the patterned arrangements of the units in a system. He further claimed that the nature of the social system affects individuals’ innovativeness, which is the main criterion for categorizing adopters. Furthermore, technology adoption-decision process involves information-seeking and information-processing activity, where an individual is motivated to reduce uncertainty about the advantages and disadvantages of that technology. As demonstrated by Rogers (2003) the technology adoption-decision process involves five steps, namely knowledge, persuasion, decision, implementation and confirmation. These stages typically follow each other in a time-ordered manner as described below.
The knowledge stage: The technology adoption-decision process starts with the knowledge stage. Where an individual learns about the existence of new technology and seeks information about it. “What?” “How?” and “why?” are the critical questions in the knowledge phase? In this phase, the individual attempts to determine “what the new technology is and how and why it works”. According to Rogers (2003) the questions from three types of knowledge namely awareness-knowledge, how-to-knowledge and
10
principles-knowledge. Awareness-knowledge represents the knowledge of the technology’s existence and it can motivate the individual to learn more about the technology and then to adopt it. With the type of how-to-knowledge contains information about how to use the technology at the expected level correctly. According to Rogers (2003) how-to-knowledge is an essential variable in the technology adoption-decision process. To increase the adoption chance of the technology, an individual should have a sufficient level of how-to-knowledge prior to the trial of this technology. On the other side, principles-knowledge is the knowledge that includes functioning principles describing how and why the technology works. The technology can be adopted without this knowledge, but the misuse of the technology may cause its discontinuance. For Seemann (2003) to create new knowledge, technology education and practice should provide not only a how- to experience but also know-why experience. In fact, an individual may have all the necessary knowledge, but this does not mean that the individual will adopt the technology because the individual’s attitudes also shape the adoption or rejection of the technology.
The Persuasion stage: This stage occurs when an individual has a positive or negative attitude toward the new technology, but the formation of a positive or negative attitude toward the technology does not always lead directly or indirectly to an adoption or rejection The individual shapes his or her attitude after he or she knows about the technology, so the persuasion stage follows the knowledge stage in the technology adoption-decision process. Furthermore, Rogers (2003) states that while the knowledge stage is more cognitive- centered, the persuasion stage is more effective-centered. Thus, the individual is involved more sensitively with the innovation at the persuasion stage.
The decision stage: In the technology adoption-decision process, the decision stage is where an individual chooses to adopt or reject the new technology. If the technology has a partial assessment basis, it is usually adopted more quickly, since most individuals first want to try the technology in their own situation and then come to an adoption decision. The clear assessment can speed up the technology adoption-decision process. However, rejection is possible in every stage of the technology adoption-decision process.
The implementation stage: In this stage, the technology is put into practice. However, the technology brings the newness in which some degree of uncertainty is involved in diffusion. Uncertainty about the outcomes of the technology still can be a problem at this
11
stage. Thus, the implementer may need technical assistance from change agents and others to reduce the degree of uncertainty about the consequences.
The confirmation stage: The technology adoption-decision already has been made, but at the confirmation stage the individual looks for support for his or her decision. According to Rogers (2003), this decision can be reversed if the individual is exposed to conflicting messages about the innovation. However, the individual tends to stay away from these messages and seeks supportive messages that confirm his or her decision. Thus, attitudes become more crucial at the confirmation stage. Depending on the support for adoption of the technology and the attitude of the individual, later adoption or discontinuance happens during confirmation stage.
2.2. Improved maize varieties adoption and diffusion
Is the nearly everyone widely cultivated cereal after teff in terms of area but is produced by more farms than any other crop (close to 8.8 million farming households). It accounts for the largest share of production by volume at 25.8%. Is grown chiefly between elevations of l500 and 2200 masl and requires large amounts of rainfall. Suitable temperature for maize is in the range of 19- 300c. The soil type, clay loam is preferred for maize production. In addition to food grain, maize residues are also used as fodder, fencing materials, and cooking fuel (Tewodros et al., 2016).
The adoption of new technologies such as fertilizer and improved seed is central to agricultural growth and poverty reduction efforts (Tura et al., 2010). Likewise, in sub- Saharan Africa, adoption of improved maize is indicated to have positive outcomes (Alene et al., 2009).
Barret (2001) in Ethiopia observed that, farmers continue to lose in terms of crop yields despite introduction of new agricultural technologies since the cost of fertilizers and improved seeds continue to be high. He further said that, if the technology is not cost - reducing, farmers are not likely to adopt it in future seasons unless policy options such as provision of credit facilities are effective.
Tura et al. (2010) analyzed the factors that explain adoption as well as continued use of improved maize seeds in one of the high potential maize growing areas in central Ethiopia.

Improving maize production is considered to be one of the most important strategies for food security in Mozambique. However, chemical fertilizers and improved maize varieties, i.e., hybrids and open pollinated varieties (OPVs) whose traits have been improved for selected characteristics such as drought tolerance, disease resistance, short maturity rate, increased yield per unit of land, and quality protein (Byerlee, 1994 ), are not yet widely adopted in Mozambique.
Amare et al. (2011) examined the driving forces behind farmers’ decisions to adopt improved pigeon pea and maize and estimated the causal impact of technology adoption on household welfare. Overall the analysis of the determinants of adoption identified inadequate local supply of seed, access to information, human capital, and access to private productive asset as key constraints for maize/pigeon pea technology adoption.
2.3. Participation of farmers in improved Maize technologies
According to Mmbando and Baiyegunhi (2016) institutional variables such as extension services and farmer’s membership of farmer-based organizations (FBO) are essential sources of information. Farmers get a lot of information with regard to production and marketing from extension officers and through a farmer-to-farmer network. Being a member of an FBO increases the probability of a farmer to adopt an IMV. Also, farmers with regular extension contacts have a higher likelihood of adopting an IMV than those with no extension contacts.
Credit may be an important factor in determining technology adoption. If a recommendation implies a significant cash investment for farmers, its adoption may be facilitated by an efficient credit program. If the majority of adopters use credit to acquire the technology this is a strong indication of credit’s role in diffusing the technology and participation of farmers in improved technologies (Assefa and Gezahegn, 2009).
2.4. Maize Production in Ethiopia
According to data collected by Central Statistical Agency 2013/2014 and 2016/17 the yield/ha of maize production with the area by hectare is compiled together in the following table:

According to the above table the yield of maize production per hectare and the used area by hectare throughout the regional of Ethiopian country were increasing respectively within two past years. Then the percentage change of yield of maize from 2013/14 to 2016/17 was increased by 12.94%. The area covered by maize production from 2013/14 to 2016/17 was increased by 7.05.
2.5. Maize production in Oromia Regional state
Maize is the first cereal crop produced in Oromia regional state and first ranked cereal crop produced when compare with other regional state of the country. The following table incorporate the Area in Hectares and Yield (Qt/Ha) together the data of maize production in Oromia Regional State collected by CSA two years (2013/2014 and 2016/2017) respectively.

Percentage change 8.41 11.54
Source: CSA (2013/2014 and 2016/2017)
The above table shows us that in East Wollega Zone the total area covered by maize in the production year of 2013/2014 Meher Season was 124,707.64 and 40.03 yield per Hectare of land and 2016/17 Meher Season was 135,191.93 and 44.65 yield per Hectare of land have been produced. Then the percentage change of yield of maize from 2013/14 to 2016/17 was increased by11.54%. The area covered by maize production from 2013/14 to 2016/17 was increased by 8.41%so when we are compared the maize production productivity per hectare of land with other cereal crops it has more potential of production for this zone and the land allocated to this cereal crop were the largest next to teff then the East Wollega zone oromia were the potential area for maize production.
Generally, East Wollega agro-ecology is comfortable for the production of cereal crops such as maize, sorghum, teff and finger millet and also for POF (pulse.oil and fababean) crops such as soya bean, haricot bean and other some crops.
2.7. Intensity of maize technology adoption
There have been few studies conducted to determine the rate of adoption of improved agricultural technologies in Ethiopia. Off-farm income has a positive but insignificant
15
effect on the adoption and intensity of use of improved maize seed. Extension services (AES) measured in number of visits per month by the extension agent to a farmer during the cropping season positively and significantly influenced the adoption and intensity of use of improved maize (Alene et al., 2000).
In analyzing the adoption of improved maize varieties, the dichotomous adopter or non- adopter classification may not give a complete picture. Even within adopters there is a wider range of variation in the intensity of maize area allocated to improved varieties. Some households allocate only limited share of their maize plots to the improved varieties while others are completely replacing the existing practices. To assess the intensity of adoption, they used the area of maize under improved varieties (Jaleta et al., 2013).
Those variables comprise educational attainment, household size, and distance from home to the farm plot, participation in demonstration fields, and membership of FBO, farm size, and previous income from maize crop. Many years in formal education is statistically significant and have a positive correlation with the intensity of IMV adoption. Thus, farmers with a relatively high level of education intensify the adoption of IMV than their counterparts with a low level of education. This is not amazing as many studies have reported a positive relationship between adoption of improved farm technology and farmers level of education (Ahmed, 2015; Deepa, Bandyopadhyay, &Mandal, 2015; Kebede &Tadesse, 2015). Household size had a significant and positive influence on the intensity of IMV.Farming in SSA; particularly in the study area is more intensive as mechanization remains rare.
Hence, having larger household size helps in the farm operations since IMV requires some farm cultural practices such as frequent weeding and application of pesticides. The results of this study agree with that of Sodjinou et al. (2015) who reported positive and significant effects of householdsize and adoption of organic farming. More extended distance from the farmer’s home to the farm plot has the potential to affect the farm business negatively as farmers may feel tired by the time they get to the farm or may have to spend extra money to commute from the house to the farm field. This is seen in the results of the study as the distance from farmers’ house to the farm plot has an inverse correlation with the intensity of adoption. The probability of farmers adopting and intensifying the IMV is higher in households with larger farm sizes than those with smaller farm sizes. This is
16
because farmers with larger farm sizes are usually into commercial farming and will usually plant IMV for profit maximization.
However, Lunduka, Fisher, and Snapp (2012) reported negative and significant effects of farmland holdings and opened pollinated variety of maize in Malawi. Previous income from maize farm did not meet our a priori expectation. The estimated results show that the probability of farmers intensifying IMV on their farmland is low for farmers who had more income from their maize farm in the previous season than those who had little income. This could partly be attributed to the fact that farmers who had more revenue in the last season might have diversified their income into other farm or non-farm business. Farmers participating in demonstration farms or on-farm trials have a higher probability of allocating a more significant proportion of their maize farmland to IMV compared to those who did not participate as indicated in the empirical findings. Through expression (demonstration) farms, farmers become aware of the attributes of IMV and acquire sufficient knowledge to make adoption decisions. Farmers learn more and become more sensitize through visuals and hands-on than hearing, hence the importance of demonstration fields.
These results go together those of Mmbando and Baiyegunhi (2016) and Gecho and Punjabi (2011). Finally, farmer’s membership of FBO variable is significant and positively related to the intensity of IMV adoption, implying that farmers belonging to FBOs adopt IMV more than the non-members of FBOs. Similar results were reported by Mmbando and Baiyegunhi (2016) in Tanzania, Ojo and Ogunyemi (2014) and Ugwumba and Okechukwu (2014) in Nigeria.
2.8. Farmers Perception on maize technology attributes
According to Jeffrey Pickens (2005), perception is the process that organizes and interprets by our sensory in order to give meaning about the environment. It is the set of processes by which an individual become aware of and interprets information about the environment. The person interprets the stimuli into something meaningful based on their past experiences. However, an individual interprets or perceives may be different from reality. Van den Ban and Hawkins (1998) defined perception is a process by which we receive information or stimuli from our environment and transform it into psychological awareness. However, all innovations do not diffuse at the same rate. Various innovations are objectively differ and probably are perceived as being different by farmer decision
17
maker. Thus, perception of differences would affect decisions to adopt or reject a particular innovation. Therefore, farmers receive and gather stimuli that indicate the attributes of improved maize technologies are superior over local and traditional one or not. Rogers (1983) has classified characteristics which may describe an innovation and individuals’ perception, which predict their rate of adoption. These characteristics of innovations are: relative advantage to current tool or procedure, compatibility with the pre- existing system, complexity or difficulty, trial ability (testability) and observably of its effects. These qualities interact and judged as a whole.
According to Duvel (1975) perception is a key dimension in behavioral change process. Perception about the relative advantage of different attributes of high yielding maize varieties was assumed to have positive effect on adoption of high yielding maize varieties. Accordingly, farmers’ perception for higher yield potential, better price, resistance to diseases, shattering resistance and lodging, short maturity and stay for long period of high yielding wheat varieties were asked. Hence, better perception towards those attributes was expected to positively influence the adoption of high yielding maize varieties and market supply Habtemariam (2004) prove this hypothesis.
According to the Shiferaw et al.,(2009) factors related to the characteristics and performance of the technology and practices include food and cash generation functions of the product, the perception by individuals of the characteristics, complexity and performance of the innovation, its availability and that of complementary inputs, the relative profitability of its adoption compared to substitute technologies, the period of recovery of investment, local adoption patterns of the technology, the susceptibility of the technology to environmental hazards, etc were the criteria for select the improved agricultural technology.
Anne et al.,(2014) using a multivariate probit model on the perception of farmers variety attributes showed that improved varieties had desirable production and marketing attributes while the local varieties were perceived to have the best consumption attributes. Evidence further indicated that the major sorghum variety attributes driving rapid adoption are taste, drought tolerance, yield, ease of cooking, and the variety’s ability to fetch a price premium. Early maturity, a major focus of research was found to have no effect on the adoption decision. (The role of varietal attributes on adoption of improved seed varieties: the case of sorghum in Kenya)
18
According to AbaKemal et al.,(2013) most of farmers (98 %) in all PAs, except Sheki Sherera and Gora Silingo, identified the maturity period of cultivars as the second most important after yield, while plant height was ranked second to yield by 70% of the farmers in two PAs, Sheki Sherera and Gora Silingo (data not shown). Farmers of these two PAs strongly preferred intermediate plant height after yield and explained that short statured cultivars were more prone to attacks by either wild or stray domestic or wild animals such as dogs and porcupines than an intermediate or a tall variety. Conversely, tallness was not desirable because of the associated problem of lodging. On the other hand, most farmers who preferred early maturity as the second most important trait explained that they usually practice a relay cropping system whereby pulse crops, such as chickpea (Cicerarietinum L.) and grass pea (Lathy russativus L.), would be sown immediately after physiological maturity of maize and before the land dried out completely. Earliness is a relative term because the farmers preferred intermediate season cultivars to very short season cultivars. Marketability ranked fourth among farmer-preferred traits. During group discussions, farmers explained that a cultivar whose grains have a glossy (flint-textured) characteristics and hard endosperm types command better acceptability in local markets than dent- textured and chalky types, when sold as both green and grain maize. Farmers’ also considered local varieties to provide superior quality in the preparation of traditional beverages. But in terms of all other characters listed, local varieties were considered inferior to the improved cultivars. In general, farmers in all PRA areas were not concerned much about storability and feed quality in maize and ranked them low. Farmers argued that they had not seen a maize cultivar with resistance to storage pests or with special qualities as feed for animals.
2.9. Empirical studies on farmers’ adoption of improved maize varieties
Through demonstration farms, farmers become aware of the attributes of IMV and acquire sufficient knowledge to make adoption decisions. Farmers learn more and become more sensitize through visuals and hands-on than hearing, hence the importance of demonstration fields. These results complement those of Mmbando and Baiyegunhi (2016) and Gecho and Punjabi (2011). Finally, farmer’s membership of FBO variable is significant and positively related to the intensity of IMV adoption, implying that farmers belonging to FBOs adopt IMV more than the non-members of FBOs. Similar results were
19
reported by Mmbando and Baiyegunhi (2016) in Tanzania, Ojo and Ogunyemi (2014) and Ugwumba and Okechukwu (2014) in Nigeria.
According the result of Assefa and Gezahegn (2009) that younger farmers, famers with larger land size, farmer living closer to market, and farmers who had closer contact with the extension system are more likely to adopt new technology and use it more. The result underscores the need for research and extension programs to be sensitive to the needs of farmers when developing and disseminating technologies that are relevant to their agro‐ecologies.
According to Jaleta et al.,(2013) results by using Poisson, binary and multinomial Probit, Tobit and Heckman’s selection models show that household characteristics, availability of family labor, wealth status, social networks, and access to credit to buy seed and fertilizer, better soil fertility and depth, market opportunities (number of traders known in villages) affect the number of improved maize varieties known to farmers, their adoption and intensity of farm area allocated to improved varieties, and the use of freshly purchased hybrid and/or OPV maize varieties. Generally, institutional arrangements that strengthen farmers’ access to input and output markets and accumulation of wealth could enhance the knowledge and use of improved maize technologies for better productivity and household income.
According to Julius (2016) paper there are four results. First, the findings suggest that the adoption of improved maize varieties is determined by a whole range of factors that include land cultivated, education of the household head and the total asset holdings of the household. Second, the results show that the adoption of improved maize varieties is associated with higher levels of income, food security, child nutritional status and lower levels of poverty. Third, the counterfactual analysis applied in this thesis shows that if non- adopters had adopted improved maize varieties, they would have realized higher levels of welfare than they currently have. Fourth, the results show that adoption of improved maize alone has greater impacts on maize yields, but given the high cost of inorganic fertilizer that limits the profitability of adoption of improved maize, higher household incomes are associated rather with the adoption of multiple SAPs.
The paper done by Tura et al., (2010) analyzes the factors that explain adoption as well as continued use of improved maize seeds in one of the high potential maize growing areas in
20
central Ethiopia. Using a bivariate probit with sample selection model approach, the study provides insights into the key factors associated with adoption of improved maize seed and its continued use. The result revealed that human capital (adult workers, off-farm work and experience in hiring labor), asset endowment (size of land owned), institutional and policy variables (access to credit, membership in farmer cooperatives union) all strongly influence farmers’ decisions to adopt improved maize varieties, while continuous use of the seed is influenced by the proportion of farmland allocated to maize, literacy of the household head, involvement in off-farm work, visits by extension agents, farmers’ experience, household land size, and fertilizer usage. Accordingly, policies and interventions that are informed about such factors are required to accelerate adoption and continued use of improved maize seeds in order to increase farm yields and remedy shortage of food and fight food poverty and insecurity more effectively and more sustainably.
According to the paper written by James et al., (2014) Intensity of adoption of improved maize varieties varies continuously and this feature allows estimation of the dose response function. The dose response function was estimated using generalized propensity score useful for analyzing causal effects of continuous treatments. The results indicated an increasing dose response function between intensity of adoption and per capita food consumption expenditure.
2.10. Conceptual framework
Agricultural technology adoption patterns often vary from one smallholder farmer to another and this variation is due to the disparity in institutional and socioeconomic factors. As it was demonstrated by CIMMTY (1993) farmers’ decision to adopt or not to adopt new technologies can be influenced by the factors related to their objectives and constraints, these factors include farmers’ endowments which can be measured by farm size and assets ownership, size of the family labors, age, formal education and institutional support system available for inputs.
Adoption of technologies is the outcome of several interactions of farmers’ internal and external contexts. Demographic factors(House head age, House head education, House head farm experience, Family size), economic factors (owned livestock , owned oxen, farm income and off farm income), institutional factors (distance to nearest market, ,
21
frequency of extension contact ) and social factors (Membership of farmers’ cooperatives union) and farmers perception towards to improved maize on local maize are the main key variables that were expected to influence the adoption of improved maize varieties in the study areas were summarized in figure1.

3.2. Data Types, Sources of Data and methods of Data collection
For this study both quantitative and qualitative data were collected. This study used both primary and secondary data. The data was collected from primary sources generated through structured questionnaire. Secondary data was collected from internet, through the desk review; the study assessed the existing literature on the perception of farmers’ on improved maize varieties and the factors affecting adoption and the intensity of use of improved maize varieties. The data was collected by the instrument Survey questionnaire and by FGD organizing together for both quantitative and qualitative data collection respectively. For FGD from three kebele three group were arranged by which one group contains 8 group, totally 24 sampled house hold were selected from the three kebele with the kebele experts for some of my qualitative data.
3.3. Sampling procedures and Sample Size
This study implemented two- stage sampling procedures to collect the required primary data. In the first stage, out of 19 kebeles in Kiremu district three kebeles were selected using simple random sampling. Secondly, stratified random sampling method was employed to identify sample households for inclusion in the study. To this effect, list of adopter households was obtained from district agricultural office (district agricultural office,2018) and from development agents at each sample kebeles and then households in the area were categorized into 2 strata, that is 1291 adopter of improved maize households, and 1223 non-adopter households. Finally, sample of adopters and non-adopters were selected by using simple random sampling. The sample keeping the proportion to each kebeles were selected by using Yamane (1967) sample size formula and 7% Precision Level Where Confidence Level is 95%.
