Abstract The present investigation aimed to study the effect of mineral nitrogen,biofertilization and foliar spraying with ascorbic acid on wheat crop, at the experimental farm of faculty of agriculture, El-Minia university during 2000/2001 and 2001/2002. The experimental design was split-split plots in randomized complete blocks: The main plot were devoted for two ascorbic acid levels spraying (without ascorbic acid and foliar spray with ascorbic acid 500 ppm).The sub-plots were occupied by the five nitrogen levels applications (zero,20,40,60 and 80 KgN/fed.).The sub-sub plots were for three treatments of biofertilizer i.e. (control”uninoculation”,inoculation by cerealin and inoculation by biogen).Combination of three factors resulted in 30 treatments (2X5X3) each block |
