Responses of grain sorghum varieties to irrigation frequencies were studied at the National Corn and Sorghum Research Center. The results showed beneficial effects on some agronomic characteristics, leaf water content, soil moisture content, yield components and grain yield with increasing irrigation frequency. Lodging and shoot fly damage were reduced by increasing irrigation frequency. The irrigation with 7 days intervals tend to give the best yield. Varietal differences were observed in agronomic characteristics, shoot fly damage, lodging, yield components and grain yield. Based on grain yield and agronomic data, the result suggest a tendency for Pioneer 8199 and Goldfinger to be superior to other cultivars under the drought condition
