Since water is a limiting factor in producing in Sistan area, saving water even in only one bar of irrigation can be economically useful. This research was conducted in first half of 2011 in agricultural and natural resources research station in form of experimenting the split plot in form of randomized complete block for investigating the effect of cutting irrigation in different stages of growth on the agronomic traits of grain sorghum variety in three repetitions. Irrigation treatment as the main treatment was considered in four stages including S : control treatment, S : cutting irrigation during vegetative phase, S : cutting irrigation during 1 2 3 vegetative growth stage, S : cutting irrigation during vegetative growth stage and the varieties were cultivated 4 in three levels as the sub-treatment: V -Sepideh, V -Payam and V -KGS . The results showed that the treatment 1 2 3 11 of cutting irrigation in the stages of growth, varieties and their interaction of variety and cutting irrigation in the stages of growth with the probability of one percent became significant; in the way that treatment of S (controlling treatment) had the maximum of grain production (3666.1 kg/hectare) comparing with other 1 treatments and the S (cutting irrigation in vegetative growth stage) and S4 (cutting irrigation in the vegetative 2 stage) were placed in next stages with 3238.9 and 3115.4 kg/hectare respectively. Among the varieties, the Sepideh variety had the maximum average (3612.5 kg/hectare) with respect to the amount of grain production (3612.5 kg/hectare) and then the variety of KGS with 3402 kg/hectare is placed in next position. The effect of 11 interaction between the varieties and the treatments of cutting irrigations showed that the variety of Sepideh with the yield of 4250 kg/hectare has the best average in the controlling treatment. The variety of KGS with 11 the yield of 4048.3 kg/hectare in observing treatment is in next position after the Sepideh. Also, these two varieties showed excellence comparing with the Payam variety in the treatment of cutting irrigation
