Abstract:

A 2-yr field study was carried out in the Research and Experimental Center of Faculty of Agriculture at Moshtohor, Benha University, Egypt, during 2006/2007 and 2007/2008 seasons. The aim of this study was to study the effect of 3 planting dates (PD) (November 1, November 15 and November 30), 2 bio- fertilization treatments (BF) (with and with out) and 4 mineral NP fertilizer levels (N0P0, N30P15, N60P30 and N90P45 kg/fed.*) on yield, yield components, grain protein content (GPC) and grain NPK uptake of wheat cv. Sakha 93. Results showed that the highest values of number of tillers and spikes/m2, 1000- kernel weight, grain yield/fed and grain NPK uptakes were obtained when wheat was sown on mid-November. Early or delayed planting significantly reduced forenamed traits. Increasing fertilizer level up to N90P45 kg/fed significantly increased yield and yield components compared with lower fertilizer levels and the control. Bacteria inoculation significantly increased number of spikes/m2, plant height, spike length, 1000- kernel weight, grain yield/fed, GPC% and grain NPK uptake compared with without inoculation in both seasons. Significant interaction effects PD x BF, PD x NP and BF x NP on grain yield and some of its attributes were detected. Whereas, no significant effect of second order interaction was found on any of the studied traits. Key Words: wheat, Triticum aestivum L , Bio-fertilizer, NP levels , Grain yield
