Abstract
Rice (Oryza sativa, L.) is one of the most important agricultural food crops for more than half of the world population. Moreover, it’s a very important cereal crop in Egypt for both consumption and export. The total cultivated area by rice is about 1.620 million feddan which produced about 6.228 million tons of paddy rice with average yield 3.85 t/ fed., (EAS 2023). Highly productivity depends on high grain quality and apply cultural practices, so to increase the national production should be increase the total area covered with high grain quality. High quality grain reflects on the increasing national income (Manzoor etal (2008).
