This book was released on 2009-05-07 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.

Download or read book The Political Economy of Agricultural Policy Reform in India written by Regina Birner and published by Intl Food Policy Res Inst. This book was released on 2011 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural policy reform is one of the major challenges facing India today. Such reform is required to reduce poverty through faster agricultural growth and to promote more sustainable use of natural resources while ensuring food security. Subsidy policies that promote the use of fertilizer and of electricity for groundwater irrigation are in particular need of reform. While subsidies for these two inputs played a crucial role in achieving India's Green Revolution, they have been criticized during the past decade for benefitting large-scale farmers more than smallholders, placing a fiscal burden on the state, and having negative environmental effects. By analyzing the evolution of these input subsidy policies and examining the political processes involved in efforts to reform them, this study throws new light on the factors that have so far prevented a move toward more pro-poor and environmentally sustainable agricultural input policies in India. The authors show that electoral politics, institutional factors, and policy paradigms or belief systems all play an important role in blocking reform. They identify several policy reform options as well as political strategies that can overcome past obstacles to reform. Community-based policy solutions, new coalitions for policy reform, fresh approaches to the policy debate, innovative and consensus-oriented forms of deliberation, and effective use of research-based knowledge can all make positive contributions to Indian policy reform. The analyses and proposals presented in this study will be a valuable resource for policymakers and stakeholders concerned with the politics of agricultural development.

This book was released on 2019-01-25 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of fertilizers that do not meet the nutrient requirements (i.e. balanced nutrient application) of target crops is a widespread problem in India. Farmers overuse urea (N) and seldom apply secondary nutrients (Sulphur, Calcium, and Magnesium) and micro-nutrients (like Zinc, Iron, Copper, Boron, Molybdenum and Manganese) in their plots. This imbalanced application of nutrients affects both long-term health of the soil as well as farmers’ own net incomes from agriculture. How do we deploy scientific research, business innovations, and public policies and programs to help promote balanced use of fertilizers in Indian agriculture?

Download or read book Sustainable Growth of Agriculture in India written by S. K. Mishra and published by M.D. Publications Pvt. Ltd.. This book was released on 1994 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book shows that the instant need to feed the teeming millions propelled us to increase the use of chemical fertilizers and adopt better agricultural practices which have created multifaced problems in agriculture. However, these methods have been killing the natural fertilizing potential of soil. The persistently growing use of external nutrients has enormously raised the cost of farming thus turning agriculture into an unremunerative occupation. Excessive use of chemical fertilizers has also been causing long-term hazards to soil fertility and intensifying the need of subsidy on domestic and imported fertilizers. All these hinder sustainable growth of agriculture. The study also shows that prices of inputs , which farmers have been using, have increased at a much faster rate than those of agriculture output causing impoverishment, in real sense, among them and making agriculture an occupation of last resort.

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.

Download or read book Contract farming productivity and fertilizer usage Empirical evidence from specialty crop production written by Mishra, Ashok K. and published by Intl Food Policy Res Inst. This book was released on 2018-11-14 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the impact of contract farming (CF) in baby corn production on yield, irrigation costs, fertilizer costs and usage of chemical fertilizer. We find that adoption of CF by baby corn smallholders, after controlling for characteristics of both control and treatment groups, leads to higher yields and lower spending on fertilizers and irrigation. Additionally, CF in baby corn farming leads to a reduction in the use of chemical fertilizers (Urea and DAP). Thus, CF intervention benefits the livelihood of smallholders, reduces environmental degradation and reduces stress on groundwater without compromising yield.

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.
