This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.

Download or read book Crop Responses to Environment written by Anthony E. Hall and published by CRC Press. This book was released on 2018-02-19 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following in the tradition of its predecessor, Crop Responses to Environment, this fully updated and more comprehensive second edition describes aspects of crop responses to environment that are particularly relevant to the development of improved crop cultivars and management methods on a global scale. It includes an extensive discussion of the difficulties in developing agricultural systems that accommodate increasing human needs for agricultural products during the twenty-first century in a sustainable manner. The book features new sections on adaptation to global climate change including adapting to global warming, elevated atmospheric carbon dioxide concentration, and increased flooding and salinity through plant breeding and changes in crop management. Warming effects include stressful effects of heat on pollen development and reduced winter chilling effects on fruit and nut trees. The book examines principles, theories, mathematical models, and experimental observations concerning plant responses to environment that are relevant to the development of improved crop cultivars and management methods. It illustrates the importance of considering emergent plant properties as well as reductionist approaches to understanding plant function and adaptation. Plant physiological and developmental responses to light and temperature, and plant water relations are considered in detail. Dr. Hall also describes climatic zone definitions based on temperature, rainfall, and evaporative demand in relation to plant adaptation and the prediction of crop water use. Irrigation management and crop responses to salinity, flooding and toxic levels of boron and aluminum are considered. Crop responses to pests and diseases as they interact with crop responses to physical and chemical aspects of the environment are examined. The book concludes with analyses illustrating the relevance of crop responses to environment to plant breeding.

Download or read book Crop Yield written by Donald L. Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been prepared for those seeking a better understanding of the functioning of crop plants, particularly the processes that lead to the genera tion of products valued by human beings. The contributors, who are among the world's foremost experts on the important crops upon which humanity depends for food or fibre, address the relevant processes for their specific crop. Currently, the world population is continuing to increase. It is projected to plateau around the middle of the next century, and while there is considerable controversy regarding the population level when this plateau is achieved, most estimates are in the area of 10 000 000 000. At present, there are about 800000000 people in the world who do not have secure access to food. Over the last 50 years various aspects of agricultural research have been combined to increase the output of world crops approximately 2.5-fold. Given the need to feed the increasing population, and to provide better access, it is predicted that during the next 50 years the agricultural research community must repeat this achievement.
