Improving winter wheat water use efficiency in the North China Plain NCP , China is essential in light of current irrigation water shortages. In this study, the AquaCrop model was used to calibrate, and validate winter wheat crop performance under various planting dates and irrigation application rates. These results suggest that frequent irrigation with a small amount of water significantly improved BY and GY. Collectively, these results indicate that the AquaCrop model can be used in the evaluation of various winter wheat irrigation strategies. Therefore, we concluded that AquaCrop is a useful decision-making tool for use in efforts to optimize wheat winter planting dates, and irrigation strategies.

Sensitivity analysis of FAO 33 crop water production function

Pasquale Steduto ; Theodore C. Food production and water use are inextricably linked. Water has always been the main factor limiting crop production in much of the world where rainfall is insufficient to meet crop demand. With the ever-increasing competition for finite water resources worldwide and the steadily rising demand for agricultural commodities, the call to improve the efficiency and productivity of water use for crop production, to ensure future food security and address the uncertainties associated with climate change, has never been more urgent.

Nicola Lamaddalena ; J. The main objective of this publication is to analyse the performance of pressurized irrigation systems operating on-demand also under other conditions and to provide revised criteria for the design of such irrigation networks.

Calculation examples have been included to demonstrate the procedures and facilitate the understanding and practical use of formulae. This publication should be of particular interest to irrigation district managers, consultants, irrigation engineers and companies, university professors, students of irrigation engineering and planners.

This paper presents updated technology for assessing soil salinity based on measurement of electrical conductivity. The technology has been extensively and successfully field tested, and it is sound, reliable, accurate and suited to a wide variety of useful applications. The required equipment is commercially available.

The advocated instrumental methodology is practical, cost effective and well developed for all general applications. It is cheaper, faster and more informative than traditional methods of salinity measurement based on soil sampling and laboratory analysis.

This publication presents an updated procedure for calculating reference and crop evapotranspiration from meteorological data and crop coefficients. The publication incorporates advances in research and more accurate procedures for determining crop water use as recommended by a panel of high-level experts organized by FAO in May The first part of the guidelines includes procedures for determining reference crop evapotranspiration according to the FAO Penman-Monteith method.

These are followed by updated procedures for estimating the evapotranspiration of different crops for different growth stages and ecological conditions.

Abstract This paper presents the results of sensitivity analysis of FAO. Paper in its present form, FAO commissioned a number of papers.

Box , Gondar, Ethiopia. Sesame Sesamum indicum L. It is the second most important agricultural commodity for export market in the country. It is well suited as an alternative crop production system, and it has low crop water requirement with moderate resistance to soil moisture deficit. The low land of North Western Ethiopia is the major sesame producer in the country, and the entire production is from rainfed.

Water is essential for crop production and best use of available water must be made for efficient crop production and high yields. For application in planning, design and operation of irrigation schemes, it is possible to analyze the effect of water supply on crop yields. Water deficits in crops, and the resulting water stress on the plant, have an effect on crop evapotranspiration and crop yield.

Yield Response to Water Shortage

Двухцветный застыл на месте и зашелся в истерическом хохоте. - Ты хочешь сказать, что это уродливое дерьмовое колечко принадлежит. Глаза Беккера расширились. - Ты его. Двухцветный равнодушно кивнул. - Где оно? - не отставал Беккер. - Понятия не имею.

 Рего… Но… Она пожала плечами и произнесла по-испански: - Девушке возле парка. Беккер почувствовал, что у него подкашиваются ноги. Этого не может. Росио игриво улыбнулась и кивнула на немца. - El queria que lo guardara.

ГЛАВА 105 Огненный шар, рвущийся наверх сквозь миллионы силиконовых чипов, производил ни на что не похожий звук. Треск лесного пожара, вой торнадо, шипение горячего гейзера… все они слились в гуле дрожащего корпуса машины. Это было дыхание дьявола, ищущее выхода и вырывающееся из закрытой пещеры. Стратмор так и остался стоять на коленях, парализованный ужасающим, неуклонно приближающимся звуком. Самый дорогой компьютер в мире на его глазах превращался в восьмиэтажный ад. Стратмор медленно повернулся к Сьюзан.

Беккер наклонил голову и тщательно разжевывал облатку. Он почувствовал, что сзади что-то произошло, возникло какое-то замешательство, и подумал о человеке, у которого купил пиджак. Беккер надеялся, что тот внял его совету не надевать пока пиджак.

 Так или иначе, - парировала Сьюзан, - теперь мы имеем параноиков из Фонда электронных границ, уверенных, что черный ход есть во всех наших алгоритмах. - А это не так? - язвительно заметил Хейл. Сьюзан холодно на него посмотрела.

 Разумеется.  - Стратмора, похоже, удивило ее недоумение.  - Мне пришлось его проинструктировать.

Он ездил на белом лотосе с люком на крыше и звуковой системой с мощными динамиками. Кроме того, он был фанатом всевозможных прибамбасов, и его автомобиль стал своего рода витриной: он установил в нем компьютерную систему глобального позиционирования, замки, приводящиеся в действие голосом, пятиконечный подавитель радаров и сотовый телефонфакс, благодаря которому всегда мог принимать сообщения на автоответчик. На номерном знаке авто была надпись МЕГАБАЙТ в обрамлении сиреневой неоновой трубки. Ранняя юность Грега Хейла не была омрачена криминальными историями, поскольку он провел ее в Корпусе морской пехоты США, где и познакомился с компьютером.
