Download or read book Evaluation of Plant Responses to Three Plant Growth promoting Rhizobacteria and Development of Methods to Observe Bacterium plant Interactions in Situ written by Peter John McEntee and published by . This book was released on 2009 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Many PGPR have been formulated into biofertilisers/biocontrol agents and are commercially available to inoculate plants. The most commonly known and widely used PGPR are rhizobium seed inoculants for legumes. This study has focussed on three free-living nitrogen fixing bacteria) Azoarcus indigens, Azorhizobium caulinodans and Azospirillum brasilense), which are documented as having the potential to individually ehance the growth of non-legumes such as wheat (Triticum aestivum L.) and canola (Brassica napus) ... The results of the pot trial showed that none of the bacterial inoculants led to a significant increase in plant dry weight (P=0.05) over controls, that there were no significant differences between controls and innoculated plants in terms of plant nitrogen (P=0.05), nor in terms of inoculation method (P=0.05). It was decided to further investigate the interaction of the bacteria with canola and wheat in the laboratory, away from other rhizosphere competition. This led to the development of a methodology to visualise plant tissue colonisation in situ ... The methodology developed in this study will enable the future simultaneous visualisation of colonisation and infection processes of the bacteria on plants and lead to identification of sites of infection, determination of interactions and detection of endophytic effects."--Abstract.

Download or read book Microbial Strategies for Crop Improvement written by Mohammad Saghir Khan and published by Springer Science & Business Media. This book was released on 2009-08-25 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an ever-increasing human population, the demand placed upon the agriculture sector to supply more food is one of the greatest challenges for the agrarian community. In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.

Download or read book Application of a Novel Root associated Bacillus Sp as a Potential Plant Growth Promoting Rhizobacteria for Increasing Crop Production Under Controlled and Field Conditions written by Parghat Gopal and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Beneficial rhizosphere bacteria promote plant growth and development through diverse mechanisms. Application of plant growth promoting bacteria (PGPR) to cropping systems needs to undergo extensive research and development to ensure successful results when commercialized as biofertilizers. The objective of the present study is to determine the agricultural potential of a Bacillus sp., isolated from a North American corn/soybean rotation soil to improve the growth and yield of corn (Zea mays) and soybean (Glycine max). The beneficial plant growth promoting activities of Bacillus sp., were investigated under varying environmental conditions in field production systems as well as under growth chamber conditions. A growth chamber experiment was conducted simultaneously on eight different crops, corn, wheat, barley, oat, soybean, lentil, pea and canola and the bacterium with varying inoculum populations (105, 106 and 107 cfu.mL-1) was applied as a seed treatment. The plants were grown for over a month and measured growth variables such as leaf area, shoot biomass and root dry weight were all increased by inoculation with the Bacillus sp., indicating that the strain functions as an effective plant growth promoting rhizobacteria. The field trials were carried out in three soil types (clay, loam and sandy or sandy loam) and over two growing seasons (2017 and 2018). Corn (DKC39-97 hybrid) and soybean (Absolute RR) seeds were treated with Bacillus sp., and the bacterized seeds were sown on two different planting dates (early- mid May and late May- early June). The cumulative effects of the factors (soil type, planting date and bacterial population) were observed throughout developmental stages of the plants – mid-vegetative, mid-flowering, mid-grain/pod filling and harvest. The vegetative and reproductive variables including plant height, leaf area, shoot biomass, and seed weight were measured and yield was calculated for the 2017 and 2018 growing seasons. Generalized linear mixed models were used for statistical analyses and the analyses were performed with the Bonferonni-adjustment method at a 95% confidence interval. On clay loam at the early planting date, the corn yield was increased by 4.6% in the first season and 13.3% in the second season for the 105 cfu.mL-1 treatment, when compared to the control. Whereas, the yield was increased by 12.3% in the first season and 8.8% in the second season for the 106 cfu.mL-1 treatment for soybean. Based on the yield results, the Bacillus sp., could be effectively used as a PGPR to improve corn and soybean productivity under field conditions.Keywords: PGPR, Bacillus sp., corn, soybean, controlled environment, field trial"--

Download or read book Bioformulations for Sustainable Agriculture written by Naveen Kumar Arora and published by Springer. This book was released on 2016-06-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than a century has passed since the first bioformulations were introduced to the market. But there is still much to be done, explored and developed. Though bioformulations offer green alternatives and are important for sustainable agriculture, they make up only a small fraction of the total additions used to enhance crop yields or protect them from pests. There is a great need to develop bioformulations that can promote confidence among end users; accordingly, it is imperative that bioformulations to replace chemicals be reliable and overcome the shortcomings of the past. Bioformulations: for Sustainable Agriculture discusses all the issues related to the current limitations and future development of bioformulations. It examines in detail those bioformulations that include biofertilizers and biopesticides (also commonly known as bioinoculants), presenting a global picture of their development. Further chapters address diverse microbes that are already being or could be used as bioformulations. The book also discusses the techniques, tools and other additions required to establish bioformulations as trustworthy and global solutions. It assesses the types of bioformulations currently available on the market, while also considering the future roles of bioformulations, including the reclamation of marginal and polluted soils. Further, it discusses the current legislation and much-needed amendments. Overall the book provides a comprehensive outlook on the status quo of bioformulations and the future approaches needed to improve them and achieve sustainable agriculture and food security without sacrificing the quality of soils. This will be extremely important in offering chemical-free foods and a better future for generations to come.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a straightforward and easy-to-understand overview of beneficial plant-bacterial interactions. It features a wealth of unique illustrations to clarify the text, and each chapter includes study questions that highlight the important points, as well as references to key experiments. Since the publication of the first edition of Beneficial Plant-Bacterial Interactions, in 2015, there has been an abundance of new discoveries in this area, and in recent years, scientists around the globe have begun to develop a relatively detailed understanding of many of the mechanisms used by bacteria that facilitate plant growth and development. This knowledge is gradually becoming an integral component of modern agricultural practice, with more and more plant growth-promoting bacterial strains being commercialized and used successfully in countries throughout the world. In addition, as the world’s population continues to grow, the pressure for increased food production will intensify, while at the same time, environmental concerns, mean that environmentally friendly methods of food production will need to replace many traditional agricultural practices such as the use of potentially dangerous chemicals. The book, intended for students, explores the fundamentals of this new paradigm in agriculture, horticulture, and environmental cleanup.
