Grain Yield and Attributes of Bread Wheat Varieties as Affected by Irrigation System and Deprivation of Some Irrigation in Sandy Soil

Irrigation systems were significant effective on all characters except No. spikelets spike-1 in the second season only was insignificant. The highest values of all traits were gained by a drip irrigation system in both seasons. Sakha 95 variety gave the highest values and significance for height of plant, number spikes/m2, No. spikelets spike-1, weight spike and grain yield fed-1 in both seasons. Plant height, number spikes/m2, No. spikelets/spike, weight of spike and grain yield was highly significant affected by irrigation deprivation in both seasons. Significant impact of interaction between irrigation systems and wheat varieties was gained for height of plant in both seasons and spikes number/m2 and grain yield/fed in the second season only. Significant effect of interaction between irrigation systems and irrigation deprivation was obtained for plant height in the first season only and spikes number m-2 and grain yield/fed in both seasons. The interaction between wheat varieties and irrigation deprivation showed highly significant for plant height and spikes number m-2 in the first and second seasons, respectively and grain yield/fed in both seasons. Regarding the interaction effect, among irrigation systems, wheat varieties and irrigation deprivation were significant differences of plant height and spikes number m-2 in both seasons and grain yield/fed in the second season only. planting Sakha 95 variety under drip irrigation system and normal irrigation or deprivation at 125 DAS.
