Effects of water stress on water use and yield of maize

to 393.9 mm, respectively. The values of I wue and ET wue varied from 4.35 to 28.05 kg ha -1 /m -3 and 7.87 to 19.51 kg ha -1 /m -3 , respectively, mostly depending on the favorableness of the year for the onion production and irrigation water applied. K y , I wue and ET wue can be used as a good basis for onion growers in the region in terms of optimum irrigation water use, for the planning, design and operation of irrigation projects in the region, and also for the improvement the production technology of the crop.
