Book Description
Fertilizer is a vital component of strategies for expanding foodproduction. The rapid growth in population and the widening food deficits inmany tropical countries ofAsia, Africa, and Latin America call attention to those aspects of fertilization that have been neglected but are expected to yield large economic payoffs in the future. Fertilizer sulfur falls into this category. In the past fertilizer sulfur received little attention from researchers and policymakers since sulfur deficiency was not considered a serious problem. It was not a problem because of low crop yields, extensive cropping, and the incidental supply of sulfur through rain, irrigation water, manures, and sulfurcontaining fertilizers. However, the situation has changed in the last three decades. Moder nagriculture based on high crop yields, intensive cropping, improved crop varieties, and greater use of sulfur-free fertilizers and environmental regula tions restricting sulfur emissions are creating large gaps between sulfur sup ply and sulfur requirements. Sulfur deficiencies are widespread and grow ing. Consequently, the full potential of a modern agricultural system in tropical countries is not being realized. This research effort results from the recognition of the seriousness of the sulfur problem and its adverse impact on food production as well as IFDC's dedication to the development and transfer of economically ef ficient fertilizer technology to tropical countries. This study represents a comprehensive analysis ofthe technical and economic linkages between fer tilizer sulfur and food production, and it provides guidelines for future directions in fertilizer sulfur research and public policy.

Book Description
Principles of Spinning: Fibres and Blow Room Cotton Processing begins by giving basic information about the various types of fibres (natural or artificial) used as raw materials in textile manufacture, for fibre-to-yarn conversion. This information includes essential and desirable fibre characteristics along with material on cotton-growing. The book offers a brief description of conventional methods of blow-room machinery, including shortcomings and aspects of automation. Many day-to-day examples that a spinner should know are presented, and the problems solved with an aim to give the reader an idea of how to use the various technical parameters in acquiring the required working data. The book focuses on blow room sequence of machines and its functioning. Key features: Discussion of the role of electronics in management of various controls. Review of a practical perspective of modern techniques used in processing cotton through the blow room. An exclusive chapter on modern blow room concept. Solved examples and exercises. This book is aimed at senior undergraduates and graduate students in textile engineering, staple fibre processing, and the spinning of staple fibres.

Book Description
This book presents a comprehensive account of upland rice cultivation in different states of India. Upland rice system is considered as most diverse of all rice systems and each states of the country grow different varieties under a range of management conditions and cropping patterns. The 23 chapters in the book consolidate and share the knowledge on rainfed upland rice cultivation practiced in different states. It analyzes the upland rice agro-ecosystem in different states and encompasses various aspects of integrated nutrient management, pest management, varieties available and newer technologies introduced for adoption by farmers to improve the productivity of this fragile ecosystem.

Book Description
The term "alkali soil"is employed to refer to soils that have a high exchangeable-sodium-percentage; and "saline soil" is used in connection with soils having a high value for the electrical conductivity of the saturation extract. This handbook was first issued in multilithed form in 1947, and it has been widely distributed in this country and abroad. The handbook is intended primarily as a practical guide for those who are confroted with soil, plant, and water problems involving salinity and alkali The first five chapters provide a basis for the evaluation and interpretaion of measure-ments The procedures and measuring methods given in chapters 6,7, and 8 are those with which the Laboratory has had experience, and they are believed to have general applicability in the diagnosis and improvement of saline and alkali soils. This handbook is the result of the combined efforts of the entire staff of the salinity Laboratry.

Book Description
In The Globalization of Wheat, Marci R. Baranski explores Norman Borlaug’s complicated legacy as godfather of the Green Revolution. Winner of the Nobel Peace Prize in 1970 for his role in fighting global hunger, Borlaug, an American agricultural scientist and plant breeder who worked for the Rockefeller Foundation, left a legacy that divides opinions even today. His high-yielding dwarf wheat varieties, known as miracle seeds, effectively doubled and tripled crop yields across the globe, from Kenya to India and Argentina to Mexico due to their wide adaptation. But these modern seeds also required expensive chemical fertilizers and irrigation, both of which were only available to wealthier farmers. Baranski argues that Borlaug’s new technologies ultimately privileged wealthier farmers, despite assurances to politicians that these new crops would thrive in diverse geographies and benefit all farmers. As large-scale monocultures replaced traditional farming practices, these changes were codified into the Indian wheat research system, thus limiting attention to traditional practices and marginal environments. In the shadow of this legacy, and in the face of accelerating climate change, Baranski brings new light to Borlaug’s role in a controversial concept in agricultural science.
