ABSTRACT
A two-year field experiment was conducted to study the behavior of three improved Egyptian rice varieties under different rates of nitrogen fertilizer. The selected tested varieties were Sakha109 (Japonica type), Giza179 (Indica/Japonica Type), and Giza182 (Indica type). Giza179 was treated with the highest nitrogen rate and recorded the highest grain yield values. The studied varieties showed different behavior under the various nitrogen levels. Giza182 recorded a high grain yield with better nutritional value. Higher grain quality characteristics were obtained from Sakha109. Generally, increasing the nitrogen level up to 200 kg N/ha increased rice grain yield, hulling (%), milling (%), and head rice (%) as well as carbohydrate %, oil %, ash amylose %, nitrogen %, phosphorus %, potassium %, and protein % in milled rice grains.
