| Abstract | ||
| A 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 design (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 autumn season on 7/21/2019 and harvested on 11/20/2019 . The results showed that the Alternate Partial Root-Zone Irrigation treatment were better than other irrigation treatments in all field indicators, The vegetative stage gave the lowest results . I3 S4 treatment were 5567.69 Cm2 plant-1 ,7057.05, 4781,53 and 5241.92 kg.ha-1 for leaves area , shoots and root dry mater , grain yield respectively | ||
