Abstract :The experiment was carried out on split plot design with four replications under greenhouse conditions. The pots containing 5 kg of soil which is collected from the 0-20 cm depth of artificial silation area made with silty water of Kelkit River were used for this study. Nitrogen at the rates of 0, 60, 120, 180 and 240 kg/ha as urea and phosphorus at the rates of 0, 50, 100 and 150 kg P 2 O 5 /ha as triple superphosphate were applied to the soil before sowing. Additionally potassium was applied at 40 kg K 2 O/ha level as K 2 SO 4 per pot for normal plant growth. The Ribe rice variety was sown in 15 th June, 1995 and plants were harvested in 9 th October, 1995. Straw dry matter and grain yields were recorded and macro-nutrient insert ignore into journalissuearticles values(N,P,K); and micro-nutrient insert ignore into journalissuearticles values(Fe,Cu,Zn,Mn); content of straw and grain were analysed. Both nitrogen and phoshorus fertilization have increased the straw and grain yields of rice plant significantly. Maximum increase in straw yield, 29.84 g/pot, and grain yield, 13.99 g/pot, was obtained from 240 kg N/ha rate, on the other hand, 100 kg P 2 O 5 /ha had given the highest straw yield, 20.35 g/pot and grain yield, 9.35 g/pot, respectively. Macro-nutrient insert ignore into journalissuearticles values(N,P,K); and micro-nutrient insert ignore into journalissuearticles values(Fe,Cu,Zn,Mn); contents of straw and grain were significantly affected by N-fertilization, whereas only NPK content of straw and grain and only Mn content of grain were affected by P-fertilization. However, uptake of macro and micro-nutrients were significantly affected by N and P fertilizer rates.
