Effect of number of irrigations on productivity of some new bread wheat cultivars

To determine the best cultivar which exhibits strong performance with ‎normal irrigation and water stress conditions, a field experiment has been ‎achieved in two locations (Bani-Sweif governorate and Sohag ‎governorate) and four irrigation treatments {Irr 1, Irr 2, Irr 3 and Irr 4 which ‎are (2, 3, 4 and 5 irrigations after sowing one, respectively)} to evaluate ‎new bread wheat cultivars ( Misr 3, Misr 4 and Sakha 95) throughout the ‎two consecutive growing seasons of 2021-2022 and 2022-2023. The ‎findings indicated that the influence of seasons was extremely significant ‎on all the examined characters except number of spikes m-2 and number of ‎kernels spike-1 in both seasons, the influence of locations was greatly ‎significant on all the examined characters except days to each of heading ‎and maturity in the second season, the effect of irrigation treatments was ‎significant on all the examined traits except number of spikes m-2 in the 1st ‎season and days to heading and plant height in the 2nd season. The effect ‎differences between wheat cultivars were significant for all the examined ‎characters except number of spikes m-2 and 1000-kenel weight in the both ‎seasons and number of kernels spike-1 in the 2nd season. According to the ‎interaction among irrigation treatments and wheat cultivar, the three ‎cultivars have a high yield potential under normal irrigation and also have a ‎good performance under water stress conditions with some preference to ‎the novel cultivar Misr 4 which significantly surpassed the other two ‎cultivars in the 2nd season.‎
