Little is known about nutrient uptake during different growth stages of drip irrigated maize under deficit irrigation. A 2-year field study in the semi-arid region of Upper Egypt was carried out in a randomized complete block design with five replications during the summer of 2016 and 2017. ...
We measured and compared evapotranspiration (ET) of a corn hybrid in 1998 and 1999 under full and deficit irrigation at Tal Amara Research Station in the Bekaa Valley of Lebanon, and studied differences in growth, yield and water use efficiency (WUE). In both years, corn was planted in May...
Data of current irrigation water use efficiency(IWUE) of administrative area in China were collected and its spatial distribution is analyzed using geostatistical and spatial autocorrelation approaches. 基于全国各行政区的现状灌溉水利用效率数据,采用地质统计学及空间自相关分析方法对灌溉水利用效率的空间分布特...

Plastic mulching with drip irrigation is a new water-saving rice cultivation technology, but little is known on its productivity and water-saving capacity. This study aimed to assess the production potential, performance, and water use efficiency (WUE) of rice under plastic mulching with drip irrig...
Effect of alternate partial root-zone drip irrigation on yield and water use efficiency of cotton Afield experiment was conducted in the oasis region of Shiyang River basin, Gansu Province to research the effect of alternate partial root-zone drip irrig... TS Du,SZ Kang,XT Hu - 《Scientia ...
Water‐use efficiency under drip‐ and furrow‐irrigation in Hawaii's sugar industry was studied. The study method consisted of a quadratic production function describing tons of sugar per acre (TSA) with respect to water use, fertilizer use, plant cycle, cane age, irrigation method used, cane...
根据首段尾句"Drip irrigation has many advantages" 以及后三段首句可知,空处为" It + 实义动词..."句式,说明滴灌的优点,故可锁定 A、B两项,再根据A项中的 "conserves water(节水)"与下文中的" high levels of water efficiency(用水效率高)"和"less runoff(水流失较少)"是同义 复现,确定答案为A项...
Limited water resources and successive droughts in Iran have limited crop production. Therefore, modern irrigation methods to increase water use efficiency
