Abstract

Two field experiments were conducted at the Experimental Farm of Rice Research and Training Center, Sakha, Kafer El-Sheikh, Egypt during the rice growing seasons of 2009 and 2010 to evaluate the response of different rice genotypes namely, GZ8455, GZ8450, GZ7576, GZ8479, GZ8126, GZ7769, GZ7764 and GZ6522 (Sakha105) to various nitrogen levels (0, 40, 80, 120, 160, 200, 240, 280 and 320 Kg N ha-1). Yield and yield attributes were determined at maturity. A wide variation in nitrogen response was observed in the eight rice genotypes. GZ6522 produced the highest grain yield followed by GZ8455 and GZ8126. Grain yield and most of yield attributes generally increased with increasing nitrogen levels up to 160 kg N ha-1.
