Determination of Grain Quality Characters of Some Egyptian Rice Cultivars Under Low Levels of Nitrogen Fertilizer

Dalia M. Tabl and Samah M. Amer

Tow field experiments on rice crop (Oryza sativa, L.) were conducted during two summer growing seasons, 2016 and 2017 at the Experimental Farm of Rice Research and Training Center (RRTC); Sakha, Kafr El-Sheikh Egypt in cooperation with Rice Training and Technology Center (RTTC),Alexandria, Egypt to study grain quality traits of some Egyptian rice cultivars grown under low fertilizer levels . The results revealed that increasing nitrogen fertilization caused significant increase in the mean values of the most studied characters. In connection, decreasing such fertilizer levels to 50% of the recommended rates did not affect the mean values of some tested cultivars of most studied characters.
