Low levels of available nitrogen in soils may limit rice growth. An  investigation was undertaken at the farm of Rice Research and Training Center, Sakha, Kafr El-Shiekh during 2010 and 2011 rice growing seasons the objectives of this investigation was aimed to evaluate the effect of different nitrogen sources combination on growth, yield and its components of Egyptian hybrid rice 1 (EHR1). All growth traits i.e. plant height, number of tillers hill^-1, chlorophyll content as well as dry matter accumulation differed significantly by N sources combination. Application of 46 kg N fed^-1 plus 7 tons of FYM fed^-1 recorded highest values of these traits at all different growth stages, while the untreated control treatment gave the lowest ones. Applications of 46 kg N fed^-1 plus 7 tons FYM fed^-1 produced tallest panicles and highest panicle grain weight, number of panicles hill^-1. The untreated (control) treatment gave the minimum values of all traits mentioned above.
