Abstract
The aim of the present work was to study the effects of Urea and ZnSO4 on qualitative and quantitative characteristics of pomegranate fruit cv. Rabab-e-Neyriz this study was done with 2 individual experiments over 2 years (2008-2009). In experiment 1, ZnSO4 (0.0, 2.5%, 5%) at fully expanded young leaves and Urea (0.0, 1.5%, 3%) at one mounth after it and before flowering were sprayed. In experiment 2, ZnSO4 (0.0, 0.3%, 0.6%) at young fully expanded leaves (< 20 days old) and Urea (0.0, 1.5%, 3%) at 2 weaks after full bloom were sprayed. Factorial experiment based on randomized complete block design was used and comparison of means was done by duncan multiple test at p<0.01 and p<0.05. In experiment 1, results showed that urea 1.5% significantly increased TA; ZnSO4 increased TA, total weight of fruit and significantly decreased total number of fruit. Interaction of urea and ZnSo4 significantly increased fresh weight of peel and arill, TA and decreased total weight of fruit. In experiment 2, Urea and ZnSO4 had no significant effects on fruit length, TSS, yeild, fresh weight of peel and arill. Urea significantly decreased TA and AA, but it increased average fruit weight. ZnSO4 significantly increased fruit diameter, arill weight and average fruit weight.
