Abstract

To illustrate the impacts of DEFICIT IRRIGATION on yield and some agronomic characteristics of WHEAT, a study was conducted based on randomized complete blocks as a split plot design with 3 replicates and 3 treatments for 2 years. Three levels of irrigation water including: 60, 80 and 100% of irrigation water requirement (IWR) were considered as main plots and 6 varieties as subplots in an experimental site located in Kabutarabad Agricultural Research Station. Results showed that irrigation treatments had significant effect on GRAIN YIELD, 1000 kernels weight biological yield, number of grain in spiker and plant height (p<0.0 1). However, the numbers of spike per m2 and harvest index were not affected significantly. Significant differences (P<0.01) were noticed in GRAIN YIELD, plant height, biological yield, number of grain in spike and 1000 kernels weight among the cultivars. However, the effects on the aforementioned indices were not significant. Maximum WUE was noticed in the 60% IWR, equally to 1.433 Kg/m3. Tolerance to water stress (in a descending order) was found in M-73-18, Pishtaz, and Backcross Roshan, respectively. Hence, The 60% IWR is recommended for the arid and semi-arid regions.
