Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. 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.

Download or read book Sustainable Potato Production Global Case Studies written by Zhongqi He and published by Springer Science & Business Media. This book was released on 2012-05-24 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato (Solanum tuberosum L.) is grown in over 100 countries throughout the world. As a staple food, potato is the fourth most important crop after rice, wheat, and maize, and has historically contributed to food and nutrition security in the world. Global interest in potato increased recently as world food prices soared, threatening the global food security and stability. Unlike major cereals, potato is not a globally traded commodity, and prices are usually determined by local production costs. Thus, potato is increasingly regarded as a vital food-security crop and as a substitute for costly cereal imports. With such importance, the 29 chapters in the edited book address the issues of sustainable potato production. This book begins with an introduction on sustainable potato production and global food security, and then presents eight case studies selected globally and covering different issues relevant to sustainable potato production in both developed and developing countries.

Download or read book Decision support systems in potato production written by D.K.L. MacKerron and published by BRILL. This book was released on 2023-08-28 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models of crop growth and development were conceived originally for scientific purposes. Typically, they describe the mechanisms of crop production, development from emergence through tuber initiation to senescence determined by temperature and day-length. Growth is driven by solar radiation intercepted by the foliage. Yields are enhanced by the availability of water and nutrients and may be reduced by pests, diseases and weeds. The scientific models describing the processes involved are leaving the research institutes and increasingly are becoming a means of knowledge transfer for students, and most importantly, to growers and their intermediaries such as extensionists and consultants. Many decision support systems (DSS) have a mechanistic model core that assures their robustness and reliability. This book gives an overview of model-based DSS in potato production. Decision support systems are used by the processing industry to guide them to promising production areas and by breeders to identify the ideal genotype for such environments. Consultants and soil laboratories use them as well as farmers to optimize the use of nitrogen, water and chemicals to control insects, nematodes, late blight and weeds. The systems, making use of models and sensing techniques, improve yield and quality while allowing their users to improve the efficiency of use of resources, thus generating positive effects for profits and for the environment. The book also gives examples of new introductions of DSS and farmers responses. The book is intended for researchers wanting to bring their models to practice, students to learn bout DSS, intermediaries and growers to improve the performance of the potato industry or of other commodities for which potato serves as an example.

Book excerpt: This unique book provides a comprehensive, up-to-date collection of information on the genetic factors, agronomic production methods, and environmental factors that impact the content of vitamins in plants. The effect of various biotic and abiotic stress factors is discussed, and the possible role of some vitamins in plant tolerance to stress factors is also investigated. The book features eye-opening data on vast vitamin variations among farmer-cultivated plants, as well as an extensive comparison between foods grown organically and those grown by conventional methods. With increasing evidence supporting the role of some vitamins in reducing risks of various forms of human cancer, this book provides timely information for researchers, teachers, and students in agronomy, horticulture, plant physiology, food sciences, and human nutrition.
