The Effect of Iron Chelate soil applications on Damask Rose

Saline and alkaline soils can reduce availability of nutrients to plant roots, so it is recommended to soil applications Fe fertilizers on plant Root, instead of applying them insoil. To study the response of damask rose (Rosa damascena Mill.) to Fe chelate, this experiment was conducted in 2012 at Alborz research station, Research Institute of Forests and Rangelands, Karaj, Iran. Experimental design was randomized complete block designwith three replications. Treatments included without soil applications, 8 gr (at bud appearance stage), 12 gr (at bud appearance and 10 days later) for each plant. Analysis of varianceindicated that Fe application significantly affected plant height enhancement, the number of main and lateral branches, the number of flowers, essential oil percentage and essential oil yield. The highest total fresh flower weight during the period (3625.7g/plant) was achieved in12 gr soil applications, the highest number of flowers during the period (2831.67) in 12 gr soil applications and the highest essential oil percentage (0.04%) in in 12 gr soil applications. Results generally indicated that the best treatment was in 12 gr soil applications.
