Abstract
Rice is one of the major food and economic crop in Egypt. In a trial to improve grain yield ,two field experiments were carried out on clayey soil during two successive summer seasons(2004 and 2005)at Sakha Experimental Research Station (ARC) , to study the effect of soaking rice seeds for 48 hours before sowing in a nutrient solution containing a mixture of chelated Fe, Mn and Zn at 0.2% each ,with or without the biopolymer agar at 0.2% as a carrier, on the yield, yield components and chemical composition of rice grain variety Sakha 104.
The obtained results revealed that applying micronutrients by seed soaking method was very effective in improving grain and straw yields, with highly significant increase of 14.5% over control as an average of the two seasons. Also, it improved the intake of macro and micronutrients in grain yield /feddan. On the other hand , using agar at 0.2% with or without micronutrients in soaking solution had no effect on yield of grain ,straw yield and chemical composition of grains.
