Water has become increasingly scarce in northwestern China due to climate change, economic growth and burgeoning population. Improving agriculture water use efficiency is of strategic significance in promoting socio-economic water productivity for arid and semi-arid inland river basins. Based on the household-level data collected in Zhangye City, which is located in the middle reaches of Heihe ...

Potato grown for early or off-season production plays a crucial role in the economy of several areas in the Mediterranean countries. Irrigation is important for determining yield and earliness, thus a better investigation of plant response under various pedo-climatic conditions can help to improve resource use efficiency and farmer income. A two-year field research (2009-2010) was carried o...

Deficit Irrigation (DI) is a fundamental solution for efficient water use in irrigated lands under conditions of water scarcity. The aim of the present study was to evaluate the potential for water saving and yield improvements of two greenhouse tomato cultivar (Shaqayeq and Shahrzad) with use of three DI treatment ,50, ,75, and ,100, percent of full irrigation along with surface and subsurface...

To investigate yield and water use efficiency (WUE) of potato with tape and furrow irrigations, an experiment was performed at Hamadan Agricultural and Natural Resources Research Center (Ekbatan station) in 2004. The experiment was arranged in a split-plot experimental design based on completely randomized block with 3 replications of irrigation water amount as the main factor (75%, 100%, 125% ...

Automatic irrigation scheduling has been demonstrated using wired sensors and sensor network systems with subsurface drip and moving irrigation systems. However, there are limited studies that report on crop yield and water use efficiency resulting from the use of wireless networks to automatically schedule and control irrigations. In this 2011 study, a multinode wireless sensor network (WSN) s...

Yield is a function of root distribution and activity. In flood conditions, root growth and efficiency are essential for crop productivity. The goal of this study was to investigate the effect of different irrigation regimes on the root development, yield and yield components of green pepper (green Hashemi cultivars). This study, which was based on a completely randomized design with three repl...

Poor irrigation water management is one of the major factors limiting crop production inEthiopia. This study was, therefore, conducted at three different locations in the southeasternEthiopia for 2 consecutive years to investigate the effects of different irrigation depths andintervals with furrow irrigation system on tuber yield, biomass yield and water use efficiency ofpotato. The treatments ...

A field experiment was conducted over 2 years to evaluate the gas exchange, water relations and water use efficiency (WUE) of wheat under different water stress and nitrogen management practices at Crop Physiology Research Area, University of Agriculture, Faisalabad. Pakistan. Four irrigation levels, i.e. one irrigation (Irrigation at tillering stage), two irrigations (Irrigations at tillering ...
