Available in PDF, EPUB and Kindle. Book excerpt: While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

Download or read book Agriculture in Dry Lands written by I. Arnon and published by Elsevier. This book was released on 2012-12-02 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas.This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.

Download or read book Water and Crop Growth written by A.K. Kolay and published by Atlantic Publishers & Dist. This book was released on 2008 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: No crop can be grown without being adequately supplied with the requisite amount of water at the proper time. A thorough knowledge of the hydrological cycle, amount and distribution of rainfall, water resources and irrigation projects in India facilitates efficient utilization of water for crop production. Inadequate supply of water to crops in semi-arid and arid regions adversely affects agricultural production. Properties of water, the mode of its entry into the soil and its absorption by roots of crops are important for irrigation. This necessitates accurate determination of the soil moisture content, the plants and available water which is essential for growth and yield of crops. Its deficiency adversely affects their growth and yield. Irrigation must be extended to unirrigated areas in order to increase the production of food, fibre and fodder for which we must know the source of irrigation water, units and methods of measurement of water, methods of irrigating crop fields, factors affecting the choice of irrigation methods, the degree of the suitability of the available water for irrigating crops and the factors affecting the suitability of water for irrigation. As water is a relatively scarce commodity, we must know whether water of a little inferior quality can be utilized to irrigate crops. In addition, we must be familiar with the precautions which need to be taken in this regard. The accumulation of excess water in the soils of the crop fields affects the growth of crops adversely enough to reduce their yields. Choice of the method of land drainage varies with the variation in the topography of the land. It is also necessary to rectify the causes of waterlogging to bring the waterlogged land back under the plough to increase agricultural production. This necessitates drainage investigation and laying out of the proper drainage system. Water requirement of crops depends on the climate and the crop. More water is required to produce crops in the arid region than in the humid region. Crops like paddy and sugar cane require much larger amount of water than finger millet and pearl millet. The book extensively deals with all these aspects related to soil and crop production and suggests measures to enhance productivity through water conservation and proper management of water resources. It will be highly useful for the students, teachers and researchers working in this field. Besides, agriculturists and general readers will also find it useful and informative.
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.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces state-of-the-art approaches, methods and research, focusing on smart management of rainwater. In addition, it provides an overview of projects from across the world, illustrating how rainwater-smart management has been implemented in drylands. Focusing on the scientific perspective it demonstrates how rural dryland agriculture can be improved. It also documents the wealth of rainwater-smart know-how available today, and replicates and transfers results to other countries and regions, to encourage cross-sector interactions among various stakeholders, such as practitioners from governmental and public organisations, policy- and decision-makers, and teaching staff from academic scientific institutions. The contributors showcase vital lessons learned from research, field projects and best-practice examples. They address the integrated use of rainwater harvesting management with landscape restoration practices and water-, and climate-smart agriculture for food security and poverty alleviation in arid and semi-arid areas. Original research, combined with the contributors’ synthetic approach, lays a foundation for new concepts and ideas. Through case studies and research reports, the book discusses all the relevant issues necessary for the comprehensive analysis and successful implementation of the technologies in rainwater management. Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.

This book was released on 2021-08-20 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio–economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro–ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support. We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.
