A field experiment was conducted to study the uptake of N, P, K, Fe, Mn and Zn by rice fertilized with the combination of urea and composted rice straw. The highest yield of rice grains was recorded by the application of 2 tons composted rice straw plus 71.75kg N. fed^-1.The maximum 1000. grain weight obtained by the plot receiving no fertilizer. Utilization of 2 tons composted rice straw plus 51.75 kg N. Fed^-1 gave the highest value number of panicles. hill^-1. Results showed that the uptake of N, P, K, Fe, Mn and Zn increased when urea plus composted rice straw applied especially when 51.7 kg N. fed^-1 combined with two tons composted rice straw.  Data showed also that N and P uptake by rice grain was higher than uptakeby rice straw but K, Fe, Mn and Zn uptake gave the opposite trend. The results of simple correlation coefficient ( r ) between grain yield (y) and each of  total N uptake ( x1 ) , total P uptake ( x2 ) and total K uptake ( x3 )  showed that ( y ) was positively and significantly associated with x1, x2 and x3. Moreover the character most closely associated with grain yield ( y ) was the total N uptake ( x1 ) (r=0.99 ). Multiple linear regression showed that the prediction equation for grain yield (y) was formulated as follows: Grain yield = 291 + 38.7 total N uptake - 18 total P uptake + 7.7 total K uptake.
