S. Bhosale ME Scholar1 Department of E&TC JSPM’s BSIOTR, Wagholi, Pune, India [email protected], [email protected] Abstract: Diseases on plants cause significant damage and economic losses in crops. Subsequently, reduces the diseases on plant by early diagnosis results in substantial improvement in quality of the product. Incorrect diagnosis of disease and its severity leads to inappropriate use of pesticides. The goal of proposed system is to diagnose the disease by using image processing and artificial intelligence techniques on images of plant leaf. This system is divided into two phases, in first phase the plant is recognized on the basis of the features of leaf, it includes pre- processing of leaf images, and feature extraction followed by ANN based training and also classification for recognition of leaf. In second phase the classification of disease which is present in the leaf is done, this process includes K-Means based segmentation of defected area, feature removal of defected portion and the ANN based classification of disease. Then the disease grading is done on the basis of the amount of disease which is present in the leaf. Crops can be managed from early stage to harvest stage that is mature. It involves monitoring of plant diseases and also identification of disease, controlled irrigation, nutrition deficiency and controlled use of fertilizers and pesticides. Although the amount of remote sensing solutions is increasing, the availability and ground visibility during critical growth stages of crops continue to be major concerns. AGROBOT (a prototype) is a agricultural robot that can avoid challenges which is existing in big and complex satellite based solutions. Keywords: Agriculture robot, Image Processing, Soil Moisture, Humidity Sensor, ANN. I. INTRODUCTION give up the work of crop cultivation. There is therefore a need to identify these diseases at an early or superior stage and In Agriculture sector plants or crop cultivation have seen fast suggest solutions so that maximum harms can be avoided to development in both the quality and quantity of food increase crop yields. The applications like plant recognition, production, however, the presence of destructive insects and crop yield estimation, soil quality estimation etc. With the diseases on crops especially on leaves has hindered the quality existence of massive volume of plant species and their use in of agricultural goods. If the presence of pests on crops and various fields, the quality of agricultural products has become leaves is not checked properly and the timely solution is not a major issue in agriculture sector. Image processing provided then the quality and quantity of food production will technique such as machine vision system has been proven to be reduced, which results in upsurge in poverty, food be an effective automated technique. Image processing based insecurity and the mortality rate [6]. This severe effect can artificially intelligent computer vision techniques can reduce disturb any nation’s economy especially of those where 70% the computational time and as a result, the automated leaf of the inhabitants rely on the products from the agricultural disease detection can be made much faster. In future, the sector for their livelihood and endurance. One of the major farmer can obtain a consolidated view of the farm along with problems for agriculturists is to lessen or eradicate the growth decision support statistics for planning purposes. In the field of pests affecting crop yields. A pest is an organism that of agriculture digital image processing techniques have been spreads disease, causes damage or is a nuisance. The most established as an effective means for analyzing purposes in frequent pests that affect plants are aphids, fungus, gnats, various agricultural applications like plant recognition, crop flies, trips, slugs, snails, mites and Caterpillars. Pests lead to yield estimation, soil quality estimation etc. With the sporadic outbreaks of diseases, which lead to famine and food existence of massive volume of plant species and their use in shortage [3]. According to H. Al-Hiary et al [1] in most of the various fields, the quality of agricultural products has become countries farmers are used to detect pests manually through a major issue in agriculture sector. Image processing their observation of naked eyes, which requires continuous technique such as machine vision system has been proven to monitoring of the crop stem and leaves, which is a difficult be an effective automated technique. Image processing based labor intensive, inaccurate and expensive task for large farms. artificially intelligent computer vision techniques can reduce Further the early detection of diseases on plants is really the computational time and as a result, the automated leaf required as a very small number of diseased leaves can spread disease detection can be made much faster. the infection to the whole batch of fruits and vegetables and thus affects further storage and sales of agriculture products. This effect of plant diseases are very destructive as a lot of farmers were discouraged to the point where some decided to International Journal of Engineering Science and Computing, June 2016 7352 http://ijesc.org/ A.

Choice of crops is very important to reap a better harvest from intercropping. The selection of a suitable intercropping system is sort of complicated issue as the success of intercropping depends much on the interactions between the component crop species, proper management practices and favorable environmental conditions. Intercropping has a huge potential and multiple advantages. The advantages are like efficient utilization of resources, enhancement of soil fertility by including legumes as component in mixture and soil conservation through covering the greater ground cover. Moreover, intercropping reduces attack of insect pest, checks the incidence of diseases and restricts weed population and thus minimizes the use of protection plant chemicals. This article addresses an overall view with a focus on prime advantages supported by evidences from the literature based on earlier research. Highlights m Types and advantages of intercropping m Crop choice in intercropping Keywords: Cropping system, intercropping, crop productivity, sustainability The greatest challenge of the present time in the intensity.

  • (04-264-01P) Seeking a Determination of Non- Regulated Status for C5 Plum Resistant to Plum Pox Virus
    Approval of USDA-ARS Request (04-264-01P) Seeking a Determination of Non- regulated Status for C5 Plum Resistant to Plum Pox Virus Finding of No Significant Impact and Decision Notice The Animal and Plant Health Inspection Service (APHIS), United States Department of Agriculture (USDA), has prepared a final environmental assessment (EA) prior to approving a petition (APHIS Number 04-264-01p) for a determination of nonregulated status received from USDA-ARS under APHIS regulations at 7 CFR part 340. The subject of this petition, plum line C5, is genetically engineered to express the coat protein gene of plum pox virus, which confers resistance to the virus. On May 16, 2006, APHIS published a notice in the Federal Register (71 FR 28296-28298, Docket no. 2006–0084) announcing the availability of the draft EA for public review and comment for the designated 60-day comment period ending on July 17, 2006. One thousand, seven hundred twenty-five comments were received and addressed, where appropriate, in the preparation of the final EA, which is attached to this document. This includes additional discussion analysis in the final EA that addresses concerns raised in public comments. In the draft EA, APHIS considered three alternatives: Alternative A – No Action Alternative; Alternative B – Determination that C5 ‘HoneySweet’ plum trees are No Longer Regulated Articles, in Whole; Alternative C - Determination that C5 plums are No Longer Regulated Articles, in Part. APHIS proposed Alternative B as its preferred alternative because of the lack of plant pest characteristics displayed by the C5 plum. Based upon analysis described in the final EA, APHIS has determined that the preferred alternative, to grant the petition in whole, will not have a significant impact on the quality of the human environment and no Environmental Impact Statement will be prepared regarding this decision.

It was always deemed necessary to improve the agricultural industry for the development of India as a whole. With online services becoming an integral part of India, it is only natural that we take our agricultural services online. Agricultural services most usually extend to queries on information on crops, growing techniques, diseases, about fertilizers, pesticides, organic and inorganic techniques. Such queries are hard to handle person to person. With the implementation of AI to create chatbots, such problems can be faced easily. In our paper, we describe the chatbot we have created to implement agricultural services in an easier and more efficient way. This chatbot, also known as the “Agrobot” can have a one-on-one conversation with its user, acting as a virtual partner. The methodology to create and implement the chatbot has been described step by step, hence giving an insight to the overall capacity of the bot. Keywords: Agriculture, Chemical Fertilizer, Pesticide information, Chatbot, Organic Farming, I. INTRODUCTION 1.1 About the Project The Agrobot is a conversational AI bot. The name Agrobot would translate to “Agricultural bot”, created for farmers as a developmental aid for better and improved farming techniques. Hence, it would ultimately be a farmer’s or an agriculturist’s partner.
