Book Description
Ultimate success in exploiting the genetic capabilities of plants to grow in nutrient-stressed environments of the semi-arid tropics (SAT) requires a holistic view of food systems to ensure that genetic selections for improved yields on nutrient-poor soils will actually be adopted by farmers. This book sets out to address the important issue of how physiological mechanisms of nutrient uptake can best be combined with genetic options to improve the adaptation of crops to low-nutrient availability, thereby enhancing productivity of nutrient poor soils in the semi-arid tropics. The book examines (i) the sustainability of breeding for low-nutrient environments from the viewpoint of three interrelated disciplines; physiology, breeding, and socio-economics, (ii) candidate mechanisms and physiological traits to enhance uptake and utilization efficiencies, (iii) genetic approaches for manipulation of crop plants to enhance root exudation and access nutrients in the rhizosphere, and (iv) field practices and farmers' preferences for crop varieties grown in low-nutrient environments. Finally, the role of modelling in improving nutrient efficiency in cropping systems, recommendations for future research needs and strategies were highlighted. Attended by 50 international participants, this book is the outcome of the workshop held at ICRISAT-India during 27-30 September 1999 to mark the culmination of the Government of Japan/ICRISAT Project.

Book Description
As the world’s population increases the need to produce greater quantities of major staple crops such as wheat, rice, maize, potato, cassava, soybean, sweet potato, barley, and banana in order to sufficiently feed the people of the world continues to grow. Breeding Major Food Staples covers improving yields and quality of these crops through breeding and the use of molecular biology tools such as gene transfer, genome mapping, biofortification, and bioinformatics. This book will be an important reference for anyone working in crop breeding.

Book Description
In the history of the International Plant Nutrition Colloquium from its first meeting in 1954, this meeting, the 13th Colloquium, is the first to be held in Asia and will be the last in the 20th century. The 20th century has seen huge changes in the number and activities of mankind. Our population has increased from around 1. 7 billion to more than 5. 8 billion and technological innovations have completely altered our way of living. As a consequence of such rapid change, we are facing many problems including changes in our environment of a global scale. But, while food shortage has been a serious concern to mankind throughout our history, serious food shortages in the 20th century have been confined to limited times and areas. As Lester Brown discusses in this volume, farmers have increased food production heroically on demand. We, the plant nutritionists should be proud of our support to the world's farmers which has helped them make their achievement possible. During the 20th century, the science of plant nutrition also has achieved great progress as described by Jack Loneragan; it became established as a discipline firmly based in science, defined the chemical elements supporting plant growth, and has contributed to improvements in plant production and environmental quality, as readers will find in many contributions in this volume.

Book Description
A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world. Links between low contents of iodine, iron and zinc (human micronutrients) in staple grains and the incidence of human health problems are discussed, together with the ways in which the micronutrient content of food crops can be increased and their bioavailability to humans improved. Detailed treatment of topics, such as: soil types associated with deficiencies, soil testing and plant analysis, field experiments, innovative treatments, micronutrients in the subsoil, nutrient interactions, effects of changing cropping systems, micronutrient budgets and hidden deficiencies in various chapters provides depth to the broad coverage of the book. This book provides a valuable guide to the requirements of crops for plant micronutrients and the causes, occurrence and treatment of deficiencies. It is essential reading for many agronomy, plant nutrition and agricultural extension professionals.

Book Description
The basic concept of this book is to examine the use of innovative methods augmenting traditional plant breeding towards the development of new crop varieties under different environmental conditions to achieve sustainable food production. This book consists of two volumes: Volume 1 subtitled Breeding, Biotechnology and Molecular Tools and Volume 2 subtitled Agronomic, Abiotic and Biotic Stress Traits. This is volume 2 which contains 18 chapters highlighting breeding strategies for specific plant traits including improved nutritional and pharmaceutical properties as well as enhanced tolerance to insects, diseases, drought, salinity and temperature extremes expected under predicted global climate change.

Book Description
Biotechnology offers great potential to contribute to sustainable agricultural growth, food security and poverty alleviation in developing countries. Yet there are economic and institutional constraints at national and international levels that inhibit the poor people's access to appropriate biotechnological innovations. Agricultural Biotechnology in Developing Countries: Towards Optimizing the Benefits for the Poor addresses the major constraints. Twenty-three chapters, written by a wide range of scholars and stake-holders, provide an up-to-date analysis of agricultural biotechnology developments in Latin America, Africa and Asia. Besides the expected economic and social impacts, the challenges for an adjustment of the international research structure are discussed, with a special focus on intellectual property rights and the roles of the main research organizations. Harnessing the comparative advantages of the public and private sectors through innovative partnerships is the only way forward to optimize the benefits of biotechnology for the poor. The book will be an invaluable resource for both academics and policy-makers concerned with agricultural biotechnology in context of developing-countries.
