Abstract
An experiment was conducted at El-Mattaana Agricultural Research Station of Upper Egypt. A split-split plot design experiment was employed to investigate three factors: irrigation scheduling based on cumulative evapotranspiration (CPE) using ratios (I1,2,3) of 1.2, 1 and 0.8 in the main plots. The average amount of water added based on these rates was 2502, 2306 and 2022 m3 during the two seasons, respectively.; seed rates (S1,2,3) of 40, 60, and 80 kg/fed in the sub plots; and two varieties of durum wheat (Triticum durum Desf.) (V1,2), namely Beni Suef-7 and Beni Suef-8, in the sub- sub plots. The irrigation levels, seed rates, and wheat varieties showed a significant or highly significant impact on all the studied traits in both seasons, and specifically, the second level of irrigation treatment (I2) demonstrated superior results in terms of wheat yield, its components, and water use efficiency compared to the other two irrigation levels. Additionally, the seed rate of 60 kg/fed showed the highest performance in most traits during both seasons. Moreover, the Beni Suef-7 cultivar demonstrated its superiority in all characteristics examined in this investigation with the exception of the number of grains per spike, where the Beni Suef-8 cultivar excelled in both growing seasons. the second-order interaction between the medium level of irrigation, the seed rate of 60 kg/fed, and the Beni Suef-7 variety resulted in the highest grain productivity and water use efficiency, with values of 25.89 and 25.67 ard/fed, and 1.68 and 1.67 kg/m3 in the first and second seasons, respectively.
