In: Mansoura Unviersity Journal of Agricultural Sciences 2006.v.31(4)Summary: Two field experiments were carried out at Sids Agricultural Research Station, Beni-Swef Governorate in the seasons of 2003 and 2004. The aims of this investigation were to study the effect of nitrogen levels (0, 80, 120 and 160 Kg N/fed) on grain yield (ard/fed)of Single Cross 10 (S.C 10) and to determine the response degree of grain yield to N fertilizer as well as to estimate the economic optimum N rate. Also to investigate the relationship between grain yield and its componen~s using some statistical techniques namely: correlation, stepwise multiple linear regression and path-coefficient. The highest grain yield (ard/fed) of the tested cultivar was produced by supplying 160 Kg N/fed in the two seasons. Quadratic model was the best of the tested models for describing the relationship between grain yield of maize hybrid to N fertilizer.
