A two-year Field Experiment was conducted during the 2013and 2014 seasons at Shambat, Sudan to study the effects of irrigation intervals on grain yield and yield components of 16 genotypes of sorghum. The experiment was laid out in split plot design with four replications. Three watering treatments consist of irrigation every week, 2 weeks and 3 weeks and 16 genotypes of sorghum. The reduction in yield obtained under prolonged watering intervals was associated with significant decrease in yield components i.e. head length, number of grains per head and 100-grain weight measured in this study. The increased of grain yield of wad ahmed, tabat and Bashaeer genotypes, even under water stress condition, was accompanied with substantial increase in yield related characters. This suggest that, the aforementioned tested genotypes showed good plasticity at least in response to irrigation intervals in this study. In conclusion, these sorghum genotypes were adapted and suitable cultivars for drought tolerant selection at the Shmabat conditions.
