AbstractA field experiment was carried out to study the effect of partial root zone irrigation on growth and yield of sorghum (Sorghum bicolor L.) in a gypsifereous Soil , at the experimental station of the college of Agriculture, Tikrit university, located at 34°40 49 and 43° 38 40 longitude and 129m above sea level . The experiment was conducted with a Randomized complete Block Pesign (RCBD). The Irrigation treatments Included Conventional Irrigation, Fixed Partial Root-Zone Irrigation and Alternate Partial Root-Zone Irrigation (I1 , I2 , I3). were applied during one of the four growth stages, which are the emergence phase, the vegetative phase, the flowering stage and seeds development (S1 , S2 , S3 , S4). Sorghum seeds (var. Inkath) were sown during the autumn season on 7/21/2019 and harvested on 11/20/2019 . The results showed that water consumption of the sorghum was 754.3,629.0,609.7,706.3 and 694.3 mm.season -1 highest for full irrigation, prd irrigation in emergence , vegetative, the flowering and seeds developmentstages respectively. I3 S2 treatment were highest, 0.94 kg m-3 In comparison with anther all treatments .Mean of full irrigation were highest 1.43 m-3 kg-1 In comparison with anther all treatments.
