EVALUATION OF FOUR PROMISING BREAD WHEAT GENOTYPES TO DIFFERENT PHOSPHORUS LEVELS FOR YIELD AND ITS COMPONENTS

The study was done during winter season 2020-2021 at field of College Agricultural Engineering Sciences, Duhok University, to evaluate the influence different phosphorus fertilizer P2O5 rate (0, 60, 90, 120kg ha-1 on yield and components four promising bread wheat Bura, Jehan-99, Apst-35 Apst-26. experiment Laid out in factorial experiments using randomize complete block design with three replications. Significant difference plant height, flag leaf area (cm), spike length(cm), No. seed spike, weight per 1000-seed total were observed by application ha-1. However, only days 75% flowering not significant affected fertilizer. Also results exhibited that Apast-35 height (104.91cm), (40 cm2), length (15.4cm), (37), (1.48g), (41.09g) 3.66 (t.ha-1). simple correlation positive between (0.89), (0.85), (0.76), (0.87) (0.92), this main these traits intributed increase under ha-1of P2O5.
