The role of manure and urea on yield and some fruit characteristics of strawberry cv. Kurdistan were studied during 2002-2004 growing season. The experiment was a factorial one based on a randomized complete block design including four levels of urea(0, 50, 100, 150 kg/ha) and three levels of manure (0, 20, 40 t/ha) in three replications. The results showed that application of manure along with urea had a significant effect on total fruit yield, and prevention of weight, fruit decay as well as leaf specific mass. The total fruit yield in 100 kg/ha of urea treatment was higher than that for the other treatments, but there were no significant differences observed with 50kg/ha of urea + 20t/ha of manure. Also the weight per fruit in 50kg/ha of urea + 20t/ha of manure was higher than that for the other treatments. The lowest post harvest fruit decay was observed with an application of 50 kg/ha urea + 20 t/ha of manure. Increasing the amount of urea increased fruit decay. Leaf Specific mass in the 50 kg/ha of urea + 20 t/ha of manure was higher than that for the other treatments. There were no significant differences observed in treatments' acidity and TSS. The results showed that an application of 50 kg/ha of ureat + 20 t/ha of manure was the most suitable treatment under the conditions.
