Abstract :

This research was done in order to study the effect of foliar application of Fe and Zn on qualitative and quantitative of rapeseed in Boin-Zahra. The experiment was conducted to split-plot as base of RCBD in 3 replications. Irrigation regime in 3 levels (I1: normal irrigation, I2: cut off irrigation at flowering stage and I3: cut off irrigation at podding stage) as main plot and foliar application in 4 levels (M1: control, M2: Fe, M3: Zn and M4: Fe +Zn) as sub plot were considered. Results showed that irrigation and foliar application as well as their interaction were significant on grain yield. Result indicated normal irrigation with mean of 3544 kg/ha had the highest grain yield. The least grain yield was observed in cut off irrigation as flowering. Foliar application of Fe + Zn resulted to increase grain yield. Results demonstrated that the most grain yield was observed in foliar application of Fe + Zn under normal irrigation.
