Abstract: 
To study the effects of different levels of N, Mn and Zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in Behshahr city, Mazandaran province, in 2009.Investigated treatments were include: Nitrogen, Manganese, Zinc.
Fertilizer source for nitrogen was urea and three rates (0, 544 and 1088 g/tree) of this fertilizer were used in this experiment. Mn and Zn microelements used as MnSO4 and ZnSO4 and the levels of these fertilizers were 0, 100 and 200 g/tree and 0 and 150 g/tree respectively. Fertilizers containing Mn and Zn micronutrients were applied to soil before bud break in winter but urea used in three split applications.
The parameters measured in this experiment were fruit yield, acidity of fruit juice and ratio of flesh to fruit juice.
The results of analysis of variance (ANOVA) of data showed that the effects of nitrogen were significant on fruit yield, acidity of fruit juice and ratio of flesh to fruit juice. But the measured traits (except the ratio of flesh to fruit juice) were not affected by the soil application of MnSO4. The effects of Zn were also significant on fruit yield, and acidity of fruit juice. The highest fruit yield (53.93 kg/tree) was obtained from the application of 1088g urea/tree. The highest ratio of flesh to fruit juice (1.3) was measured when 200g MnSO4 was used for each tree.
