Abstract
Rice is a very important cereal crop in Egypt and allover the world. In Egypt, it is an essential food crop because of shortage in wheat production, and nitrogen fertilizer is crucial to obtain a good yield. Two field experiments were conducted in 2011 and 2012 rice seasons at the Experimental Farm of Rice Research and TrainingCenter, Sakha, kafr El-Sheikh, Egypt. The experiments aimed to evaluate yield and its components of four rice cultivars; Sakha 101, Giza 178, Egyptian Jasmine and rice Hybrid 1. These cultivars were tested under five nitrogen levels; 0, 23, 46, 69 and 92 kg N/ fed. in the form of urea (46.5 % N ). Also, the insect infestations of rice stem borer, Chilo agamemnon Bles. and rice leaf miner, Hydrellia prosternalis Deeming. were evaluated. The main results proved the superiority of Egyptian Hybrid 1 rice cultivar, concerning filled grains and yield. The second rank was that of Sakha 101 cultivar as it gave the highest values of 1000-grain weight and harvest index. According to the current data, it is recommended to use 69 kg N/ fed. ( not 92 kg ) for fertilizing the tested cultivars, as no significant yield differences were found between the two nitrogen levels. On the other hand, it is important to avoid using overdoses of nitrogenous fertilizers because they encourage the infestation by rice stem borer and rice leaf miner.
