Abstract :
This research in Qazvin with aim of assess to foliar application of Fe, Zn and Ca on lentil grain yield. This experiment was done as split plot as base of RCBD with 3 replications. Humidity conditions in 2 levels (I1: without irrigation (reinfed), I2: irrigation before flowering) as main plot and foliar application in 5 levels (M1: Ca, M2: Zn, M3: Fe, M4: Ca+Zn+Fe and M5: control) as sub plots were considered. Results showed that irrigation, foliar application and their interaction had significant effect on grain yield. Results showed that supplementary irrigation resulted to significant of grain yield (811.6 kg/ha). Results also indicated that foliar application of Ca+Zn+Fe that it was in a common statistically group with Zn foliar application. Ca foliar application had the lowest impact on increase of grain yield. Result showed that the most grain yield was observed in Ca+Zn+Fe foliar application and also Zn application alone under supplementary irrigation.
