| Abstract | ||||
| Rice is an important food crop in Egypt and allover the world. Low levels of available nitrogen in soils may limit rice growth. An investigation was undertaken at the farm of Rice Research and TrainingCenter, Sakha, Kafr El-Sheikh during 2010 and 2011 rice growing seasons. The objective of this investigation was aimed to evaluate the effect of different nitrogen source combinations on growth, yield and its components of Egyptian hybrid rice 1 (EHR1). Also, the effect of fertilizer combinations on rice stem borer was considered. All growth traits i.e. plant height, 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, highest panicle grain weight, and number of panicles hill-1. The untreated (control) treatment gave the minimum values of all traits mentioned above.The rice stem borer infestation markedly decreased with the application of farmyard manure or rice compost as compared with mineral nitrogen. | ||||
