Influence of Manure and Urea on Yield and Some other Fruit Characteristics in Strawberry cv. Kurdistan

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 treatment's 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.
