Abstract
In order to evaluate the effect of Fe and Zn foliar application on agronomical characteristics of savory under different plant densities, a split plot experiment as randomized complete design with 3 replications was conducted at spring and summer seasons in Qazvin, Iran, during 2012. Foliar application in 4 levels (M1: water, M2: Fe, M3: Zn and M4: Fe + Zn) as main plots and plant density in 4 levels (P1: 50, P2: 75, P3: 100 and P4: 125 plant.m -2 ) as sob plots were considered. The results at final harvest showed that plant density had significant effect on fruit and grain yield. So that increasing plant density until 100 plant.m -2 resulted to increase fruit and grain, but effect of foliar application was not significant on fruit and grain yield. On the other hand, interaction of treatments showed that grain number was diminished per fruit with increase plant density. So that density of 125 plant.m -2 had the lowest grain number per fruit. But foliar application of Fe + Zn could be increased the grain number per fruit under density of 125 plant.m -2
