Abstract
Two field experiments was carried out at the Experimental Farm of Faculty of Agriculture, Kafrelsheikh University - North Nile Delta, Egypt, during the two successive winter seasons of 2014/2015 and 2015/2016, to investigate the effect of different nitrogen rates (60, 120, 180 and 240 kg N/ha) and phosphorus rates (0, 36 and 72 kg P2O5/ha) on yield and yield attributes of two bread wheat cultivars (Misr 2 and Giza 168) grown on clay soil conditions. Misr 2 was higher than Giza168 in values of number of days to heading, plant height, number of fertile tillers in both seasons and number of grain /spike, biological yield, grain yield and straw yield in the first season. Giza 168 recorded the highest values for 1000 grain weight and harvest index in the first season. Fertilizing with 240 kg N/ha resulted the highest values of yield attributes and significantly exceeded other studied levels (60, 120 and 180 kg N/ha). Application of 240 kg N/ha recorded the highest values of grain and straw yields (7.430 and 6.514 t/ha) and straw (12.071 and 10.119 t/ha) in the first and second seasons, respectively. P2O5had significant effect on most characters under this study. Increases P2O5 rates increased all traits except heading date and harvest index, where the inverse was true P2O5. Fertilizing with 72 kg P2O5/ha resulted the highest values of grain yield (6.564 and 6.749 t/ha) and straw yield (10.110 and 11.062 t/ha) in both seasons. Respectively. Fertilizer with 240kg N/ha and 72 kg P2O5/ha recorded the highest values for all traits in both seasons.
