Abstract

To study the effect of different deficit-irrigation methods on yield and Water Use Efficiency of wheat under different water applications a field experiment was carried out in split plot arrangement using randomized complete block design with four replications at the Research Farm of Islamic Azad University, Karaj branch, Iran in 2014-2015 growing year. Deficit irrigation with three levels were I100: use of 100% wheat water requirement, I75: use of 75% wheat water requirement and I50: use of 50% wheat water requirement, which were assigned to the main plots and irrigation methods with three levels, consisting of M1: conventional furrow irrigation, M2: fixed Alternate-furrow irrigation and M3: periodic Alternate-furrow irrigation which were assigned to the sub plots. The results showed that by using 100% wheat water requirement grain yield in the fixed and periodic Alternate-furrow irrigation methods decreased by 21. 8 and 23. 7 percents as compared to conventional furrow irrigation method, respectively. The highest Water Use Efficiency for grain yield (1. 63 kg. m-3) was obtained when 75% wheat water requirement and fixed and Alternate-furrow irrigation methods and the lowest Water Use Efficiency for grain yield (1. 24 kg. m-3) was obtained when to 50% wheat water requirement, with conventional furrow irrigation method, was used. Also, the highest Water Use Efficiency for biologic yield (4. 38 kg. m-3) was obtained at 50% wheat water requirement, with fixed Alternate-furrow irrigation method, that decreased 31. 5 percent as compared to I100M1. According to the results of this study, the application of alternate furrow irrigation with 75% crop water requirement can be used to increase Water Use Efficiency for wheat yield in the studied area.
