Abstract

In order to study the effect of irrigation-off on growth and yield of grain sorghum cultivars, a split plot experiment was carried out as randomized complete block design with three replications in the summer of 2012. Irrigation treatments included full irrigation based on 60 mm evaporation from class A evaporation pan (I0), irrigation-off ate reproductive stage (I1), irrigation-off at flowering stage(I2), irrigation-off at grain filling stage(I3) in main plots, and sop plot included grain sorghum cultivars (Payam, KGS36).The measured traits included number of grains per Ear, 1000-grain weight, grain yield, biological yield, and harvest index. The highest grain yield (394.45 g/m2) and biological yield (1066.64 g/m2) were obtained in full irrigation (control) and grain yield and biological yield in deficit irrigation treatment at flowering stage respectively decreased 46.8% and 12.5% compared with the control. The highest grain yield belonged to KGS36 cultivar by 510.53 g/m2). The interactive effect of experimental treatments showed that the highest grain yield by 440.98 g/m2 belonged to the treatment with full irrigation and KGS36 cultivar. KGS36 cultivar had the highest grain yield in two favorable and deficit irrigation conditions. Therefore, in deficit irrigation conditions it is possible to achieve acceptable yield by growing this cultivar
