This book was released on 2013-04-09 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers. Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production. This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.

Download or read book Agroecosystems of South India written by K. R. Krishna and published by Universal-Publishers. This book was released on 2010 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroecosystems of South India is a unique treatise that deals with the relevance of natural resources, genetic stocks, fertilizers, and agronomic practices on the productivity of agroecoregions. Within the context of this book, an agroecosystem has been defined as a conglomerate of small cropping zones, which may be mono-cropping expanses or intercrops that occur in various geographic regions of South India. South India abounds with several such agroecosystems that encompass field crops, vegetables, cash crops, plantations, and forest species. However, the main emphasis within this volume is restricted to agroecosystems that include major cereals, legumes, and oil seed crops. There are 10 chapters in this volume. The first, on historical aspects, traces important events related to domestication, introduction of crop species, agricultural implements, development of soil fertility and crop husbandry procedures. An introductory chapter on Agroecosystems delineates various agroecoregions of South India. Their classification based on physiography, soils, and climatic parameters have been dealt with in great detail. Descriptions on natural resources such as soils and their fertility conditions; water resources; climatic conditions including precipitation patterns; and crops and their genotypes are available in chapter 2. The impact of soil fertility and nutrient dynamics on ecosystematic functions and productivity of crops in an agroecosystem forms the central piece of discussions within chapters 3 to 9. Historical background, geographical settings, agroclimate, soils, cropping systems, and productivity trends have been provided for each cropping ecosystem. Recent advances and details on aspects of nutrient dynamics, such as soil nutrients, their availability, physico-chemical transformations, nutrient fluxes, inorganic fertilizer supply, organic manures, crop residue recycling, nutrient carry over and nutrient balances/imbalances form the core of each chapter. The impact of beneficial soil microbes such as Rhizobium, Plant Growth Promoting Rhizobacteria and Arbuscular Mycorrhizas, on nutrient dynamics in soil has also been discussed. More recent developments dealing with modeling nutrients in cropping ecosystems, computer based-simulations, precision farming and site-specific nutrient management have been emphasized. Forecasts on the impact of nutrient dynamics on the future course of agroecosystems are also available. Overall, this book is a scholarly edition that aims at providing an excellent exposition of recent developments within various agroecosystems of South India to a global audience. It highlights the importance of soil fertility and nutrient dynamics within agroecosystems to total food grain and fodder production in South India. It will be a useful book to researchers, professors, and students dealing with agriculture, environmental science, ecology, and plant science.

This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The steadily increasing cost of nitrogen fertilizer has resulted in more emphasis on basic and applied studies to improve nitrogen use efficiency in lowland rice. The efficiency of fertilizer nitrogen in farmers' fields is shockingly low ~ a luxury resource-scarce farmers in tropical Asia can ill afford. We believe it is critical to quantify the basic transformation processes and develop management practices for higher N use efficiency for two reasons. They are: 1. Nitrogen fertilizer together with water management is a key factor for achieving the yield potentials of modern rices. 2. Fertilizer nitrogen prices are high and most Asian rice farmers are poor. The International Rice Research Institute (IRRI), Philippines; Internation al Fertilizer Development Center (IFDC), USA; Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia; U.S. Universities (Louisiana, Cornell, California, Arkansas and others); and Dr Justus Leibig University in West Germany are actively engaged in individual or collaborative research that addresses basic transformation processes on N gains and losses and management practices to maximize N use efficiency in rice. It is appropriate to update and summarize, in a double issue of Fertilizer Research, the 10 papers presented at the special symposium organized by the American Society of Agronomy (ASA) at the 75th Annual Meeting in Washington, D.C. in 1983. S.K. De Datta, Head of Agronomy Department, IRRI, was chairman of the International Agronomy Division of ASA (A-6) in 1982 and 1983.

Download or read book Nutrient Use Efficiency: from Basics to Advances written by Amitava Rakshit and published by Springer. This book was released on 2014-12-26 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.
