Abstract

Field experiments were carried out at The Experimental Farm of SakhaResearch Station, Sakha, Kafr El-Sheikh, Egypt during 2020 and 2021 seasons. The study aimed to investigate the response of Sakha 109 to irrigation intervals and phosphorus levels. A strip-plot design, with three plant replications, was used. The vertical plots contained four irrigation intervals, namely: continuous flooding (CF), irrigation every 6, 9, and 12 days (D). The horizontal plots consisted of four triple superphosphate fertilizer rates as follows: Control, 24, 48 and 72 kg P2O5/ha. The results revealed that Leaf area index (LAI), dry matter /m2, plant height, number of panicles/m2, number of filled grains/panicle, panicle length, panicle weight, 1000 grain weight and grain yield significantly increased at CF and 6D, 9D, as compared to the 12D treatment. Leaf area index, dry matter, plant height, grain yield, and its components were increased significantly by the application of 48 and 72 kg P2O5/ha without significant differences between the two treatments. Continuous flooding consumed the highest amount of total applied water while, the lowest amount was exerted by irrigation every 12 days. Irrigation every 6 days gave a similar grain yield to that of CF with less amount of irrigation water and gave reasonable water productivity in both seasons. Generally, it is suitable to use irrigation every 6 days with the application of 48 kg P2O5/ha for the highest grain yield of Sakha 109 and best water productivity.
