Effects of Biofertilizers Combined with Different Soil Amendments on Potted Rice Plants
RESEARCH 157 EFFECTS OF BIOFERTILIZERS COMBINED WITH DIFFERENT SOIL AMENDMENTS ON POTTED RICE PLANTS Arshad Javaid1* ABSTRACT This pot study investigated the effect of the combined application of two commercial biofertilizers viz. Biopower and EM (Effective Microorganisms) on rice (Oryza sativa L.) growth and yield in soils amended with farmyard manure, green manure, and NPK fertilizers. Biopower is a product of the Nuclear Institute for Biotechnology and Genetic Engineering (NIBGE), Pakistan, which contains species of associative and endophytic diazotrophs. EM (effective microorganisms), a product developed by Japanese scientists, consists of co-existing beneficial microorganisms, mainly species of photosynthetic and lactic acid bacteria, as well as yeast. Applying Biopower adversely affected plant growth and yield in NPK fertilizer amendment. Conversely, this biofertilizer markedly enhanced plant growth and yield in green manure amended soil while its effect was not significant in farmyard manure amendment. In green manure amendment, applying EM enhanced grain yield by 46%. Co-inoculation of Biopower and EM evidently improved root and shoot growth in farmyard manure amended soil. This study concludes that the two biofertilizers clearly enhanced shoot biomass and grain yield in green manure amended soils. Key words: Associated N2-fixers, Biopower, effective microorganisms, rice, soil amendments. INTRODUCTION several bacteria may be isolated from sterilized surface roots of flooded rice plants, suggesting endophytic Rice (Oryza sativa L.) is probably the most important colonization (Raimam et al., 2007). The most likely cereal in the world and serves as food for about 50% of candidates for biological N fixation in rice are species the world’s population (Ladha et al., 1997). -

Biochar application to soil proves to be a suitable solution to these problems. Although the literature presents the pros and cons of biochar application, very little information is available on the impact of repeated application. In this study, we evaluate and discuss the effects of initial and reapplied biochar (both in rates of 0, 10, and 20 t ha−1) combined with N fertilization (at doses of 0, 40, and 80 kg ha−1) on soil properties and N O emission from Haplic Luvisol in the temperate climate zone (Slovakia). Results showed that 2 biochar generally improved the soil properties such as soil pH(KCl) (p ≤ 0.05; from acidic towards Citation: Horák, J.; Kotuš, T.; Toková, moderately acidic), soil organic carbon (p ≤ 0.05; an increase from 4% to over 100%), soil water L.; Aydın, E.; Igaz, D.; Šimanský, V. -

Assessment of Multifunctional Biofertilizers on Tomato Plants Cultivated Under a Fertigation System ABSTRACT Malaysian Nuclear A
Assessment of multifunctional biofertilizers on tomato plants cultivated under a fertigation system Phua, C.K.H., Abdul Wahid, A.N. and Abdul Rahim, K. Malaysian Nuclear Agency (Nuclear Malaysia) Ministry of Science, Technology and Innovation, Malaysia (MOSTI) E-mail: [email protected] ABSTRACT Malaysian Nuclear Agency (Nuclear Malaysia) has developed a series of multifunctional bioorganic fertilizers, namely, MULTIFUNCTIONAL BIOFERT PG & PA and MF- BIOPELLET, in an effort to reduce dependency on chemical fertilizer for crop production. These products contain indigenous microorganisms that have desired characteristics, which include plant growth promoting, phosphate solubilising, antagonistic towards bacterial wilt disease and enhancing N2-fixing activity. These products were formulated as liquid inoculants, and introduced into a fertigation system in an effort to reduce usage of chemical fertilizers. A greenhouse trial was conducted to evaluate the effectiveness of multifunctional biofertilizers on tomato plants grown under a fertigation system. Multifunctional biofertilizer products were applied singly and in combination with different rates of NPK in the fertigation system. Fresh and dry weights of tomato plants were determined. Application of multifunctional biofertilizer combined with 20 g NPK resulted in significantly higher fresh and dry weights as compared to other treatments.

Biological Sciences, Faculty of Sciences King Abdul Aziz Univ, KSA *Corresponding author: [email protected] Abstract The present study was conducted to investigate the effect of chemical, organic and bio-fertilizers on photosynthetic pigments, soluble sugars, non-soluble sugars, total carbohydrates and mineral elements in wheat (Triticum aestivum L.) plants grown under different concentrations of sea water (0%, 20% and 40%). Chemical fertilizer was used at concentrations of 0, 250 and 500 kg/ha; Rhizobium and Azotobacter were used as Biofertilizers; and Humic acid in concentrations of (0, 5 and 10 kg/ha) was used as organic fertilizer. The obtained results showed that photosynthetic pigments, carbohydrates and nutrient elements were markedly reduced at the high levels of sea water particularly 40% ratio. While, fertilizer treatments had an observed promotion effects on those constituents, particularly Bio and organic fertilizers that were more effective than chemical fertilizers even at high concentrations of sea water. This may be because of the potential effect of organic and bio- fertilizers on providing the nutrient elements needed by plants besides some other beneficial compounds that help plants to withstand high salt stress conditions.

Chapter 2 The Management of Soil Quality and Plant Productivity in Stressed Environment with Rhizobacteria Dilfuza Egamberdieva 2.1 Introduction The urgency of feeding the world’s growing population while combating soil pollution, salinization, and desertification has given plant and soil productivity research vital importance. Under such circumstances, it requires suitable biotech- nology not only to improve crop productivity but also to improve soil health through interactions of plant roots and soil microorganisms (Lugtenberg et al. 2002). Interest in bacterial fertilizers has increased, as it would substantially reduce the use of chemical fertilizers and pesticides which often contribute to the pollution of soil–water ecosystems. Presently, about 20 biocontrol products based on Pseu- domonas, Bacillus, Streptomyces, and Agrobacterium strains have been commercialized, but there still is a need to improve the efficacy of these biocontrol products (Copping 2004; Chebotar et al. 2000; Lugtenberg and Kamilova 2004). Soil salinity disturbs the plant–microbe interaction, which is a critical ecological factor to help further plant growth in degraded ecosystems (Paul and Nair 2008). -
Bio-Organic Fertilizers Stimulate Indigenous Soil Pseudomonas Populations to Enhance Plant Disease Suppression
Tao et al. Microbiome (2020) 8:137 https://doi.org/10.1186/s40168-020-00892-z RESEARCH Open Access Bio-organic fertilizers stimulate indigenous soil Pseudomonas populations to enhance plant disease suppression Chengyuan Tao1,2†, Rong Li1,2†, Wu Xiong3, Zongzhuan Shen1,2, Shanshan Liu1,2, Beibei Wang4, Yunze Ruan4, Stefan Geisen5,6, Qirong Shen1,2,7* and George A. Kowalchuk3 Abstract Background: Plant diseases caused by fungal pathogen result in a substantial economic impact on the global food and fruit industry. Application of organic fertilizers supplemented with biocontrol microorganisms (i.e. bioorganic fertilizers) has been shown to improve resistance against plant pathogens at least in part due to impacts on the structure and function of the resident soil microbiome. However, it remains unclear whether such improvements are driven by the specific action of microbial inoculants, microbial populations naturally resident to the organic fertilizer or the physical-chemical properties of the compost substrate. The aim of this study was to seek the ecological mechanisms involved in the disease suppressive activity of bio-organic fertilizers. Results: To disentangle the mechanism of bio-organic fertilizer action, we conducted an experiment tracking Fusarium wilt disease of banana and changes in soil microbial communities over three growth seasons in response to the following four treatments: bio-organic fertilizer (containing Bacillus amyloliquefaciens W19), organic fertilizer, sterilized organic fertilizer and sterilized organic fertilizer supplemented with B. amyloliquefaciens W19. We found that sterilized bioorganic fertilizer to which Bacillus was re-inoculated provided a similar degree of disease suppression as the non-sterilized bioorganic fertilizer across cropping seasons. -
Multifunctional Liquid Biofertilizer As An
MULTIFUNCTIONAL LIQUID BIOFERTILIZER AS AN INNOVATIVE AGRONOMIC INPUT FOR MODERN AGRICULTURE BIOBAJA CECAIR MULTIFUNGSISEBAGAI INPUTAGRONOMIINOVATIF UNTUK PERTANIAN MODEN Phua Chop Kwai Hoe and Khairuddin Abdul Rahim Agensi Nuklear Malaysia (Nuklear Malaysia) Kementerian Sains, Teknologi dan Inovasi (MOSTT), Bangi, 43000 KAJANG, Selangor E-mail: [email protected] Abstract Liquid biofertilizer is increasingly available in the market as one of the alternatives to chemical and organic fertilizers as well as solid substrate-based biofertilizers. One of the benefits from biofertilizer is the contribution from population of microorganisms available. These microorganisms may enhance the plant growth and create healthy rhizosphere. The advantage of a liquid biofertilizer is that no solid carrier is needed. These products are also developed for potential application in modem agriculture such as soilless farming systems, viz. fertigation and hydroponics. Traditionally, liquid biofertilizer is produced from fermentation of effective microorganisms which was recommended to be used within three months. Therefore, the development of low-cost and long shelf-life liquid biofertilizers was conducted at Malaysian Nuclear Agency (Nuclear Malaysia). Three biofertilizer inoculums (phosphate solubilising bacteria and plant growth promoting bacteria) were developed into four formulations of liquid biofertilizers. The liquid biofertilizers were kept at low temperatures (9 + 2 °C) and room temperatures (28 ± 2°C) for shelf-life study. Nutrient broth liquid biofertilizer kept at low temperatures showed significantly high survival rates after storage for six months as compared to other formulations and treatments.

Use of Plant-Associated Bacillus Strains As Biofertilizers and Biocontrol Agents in Agriculture
Chapter 3 Use of Plant-Associated Bacillus Strains as Biofertilizers and Biocontrol Agents in Agriculture Rainer Borriss 3.1 Introduction In spite of limited arable land coupled with rising demand of a steadily increasing human population, food supply is a global challenge making production of high- quality food, free from unacceptable levels of chemicals, a pressing need (Table 3.1). Paradoxically, this increased demand has led to the development of agricultural practices that are undesired and increase disease pressure on plants. An extreme example, impressively illustrating our situation, was recently reported (Guo et al. 2010). Overuse of N-fertilizer contributes substantially to regional soil acidification in China. Since 1980, crop production has increased with rapidly increasing N-fertilizer consumption. Decreasing N use efficiency, mainly due to increasing soil acidification, results from this practice. More and more N-fertilizer is being lost to the environment, causing further negative environmental impacts. It has been estimated that approximately one third of the food crop is destroyed every year due to attack by insects, pathogenic fungi, bacteria, and nematodes. Current worldwide potato crop losses, due to late blight caused by pathogenic fungus Phytophthora infestans, are at $6.7 billion, for instance (Haverkort et al. 2008). At present, the major strategies against damages caused by plant pathogens are chemical pesticides or resistant plant cultivars. However, there are major limitations in using both strategies. Firstly, agrochemicals do not prevent all diseases, and toxic residues can accumulate in the soil and food chain. Therefore, the use of many agrochemicals was banned or restricted, because of environmental and health risks. -
