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 Agronomic Crops written by Mirza Hasanuzzaman and published by Springer Nature. This book was released on 2019-11-23 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agronomic crops have provided food, beverages, fodder, fuel, medicine and industrial raw materials since the beginning of human civilization. More recently, agronomic crops have been cultivated using scientific rather than traditional methods. However, in the current era of climate change, agronomic crops are suffering from different environmental stresses that result in substantial yield loss. To meet the food demands of the ever-increasing global population, new technologies and management practices are being adopted to boost yields and maintain productivity under both normal and adverse conditions. Further, in the context of sustainable agronomic crop production, scientists are adopting new approaches, such as varietal development, soil management, nutrient and water management, and pest management. Researchers have also made remarkable advances in developing stress tolerance in crops. However, the search for appropriate solutions for optimal production to meet the increasing food demand is still ongoing. Although there are several publications on the recent advances in these areas, there are few comprehensive resources available covering all of the recent topics. This timely book examines all aspects of production technologies, management practices and stress tolerance of agronomic crops.

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 Effects of Regular Deficit Irrigation and Root Wetting on Yield of Potato and Pepper written by Roula Mikhael Bachour and published by . This book was released on 2009 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water scarcity is becoming a severe problem worldwide and its effect is more rel evant in arid and semi-arid regions. In order to alleviate this problem, irrigat ion water management is a must to sustain irrigated agriculture. A study was pla nned and conducted for the growing seasons 2007 and 2008 with the following obje ctives: First to study the effects of regular deficit irrigation and root wetti ng on the yield of potato and pepper, second to evaluate water use efficiency (W UE) and productivity under different irrigation treatments. The third objective is to evaluate different methods of measuring crop evapotranspiration, while the fourth objective is to study the impact of regular deficit irrigation on crop f actor. Four irrigation treatments were considered: T1, T2, T3 and T4 (filling th e top 25%, 50%, 75% and 100% of the root zone to field capacity respectively). E vapotranspiration was measured by atmometers (ETgage (Trademark)) and Nimah-mini pans. Also, actual evapotranspiration was measured from soil moisture measuremen ts using the time domain reflectometry (TDR). The highest yield of potato was ob tained in T3 (37.66 t/ha in 2007 and 36.14 t/ha in 2008). For pepper, the highes t yield was for T3 (42.5 t/ha in 2007 and 49.9 t/ha in 2008) with no significant difference (P less than 0.05) from T2. The applied water was reduced in potato by 195mm and 75mm for T2 and T3 respectively and in pepper 192mm and 69mm for T2 and T3 respectively compared to the control T4. WUE of potato was the highest i n T2 (5.46 kg/m3 in 2007 and 6.46 kg/m3 in 2008) and also for pepper T2 had the highest WUE (6.93 kg/m3 in 2007 and 9.79 kg/m3 in 2008). And the water productiv ity showed that less water is needed in T2 (0.14 m3/kg in 2007 and 0.10 m3/kg in 2008 for pepper, and 0.18 m3/kg in 2007 and 0.15 m3/kg in 2008 for potato) foll owed by T3 for both crops. ETgage (Trademark) and Nimah-minipan gave a high corr elation in evapotranspiration compared to the FAO Penman-Monteith equation. The Kc values at the development growth stage were less than those published by the FAO; they were decreased as the deficit irrigation increased.
