Abstract :

This research was carried out in order to investigate the effect of iron and zinc soluble irrigation on quantitative and qualitative yield of two rapeseed varieties. The present study was carried out in a factorial arrangement based on randomized complete block design with three replications. The investigated factors included micronutrient foliar application in 4 levels (M1: pure water (control), M2: iron sulfate, M3: Zinc sulfate, M4: iron + zinc sulfate), and rapeseed (V1: Okapi and V2: Nepton), which were factorial in experimental plots. The results of analysis of variance showed that the effect of cultivar and solubility at 1% level on grain yield was significant. The results of the comparison of mean of cultivar effect on grain yield showed that Neptune cultivar with a mean of 3441 kg. ha-1 had a significant superiority with the average of 3091 kg. ha-1 than the aphid cultivar. The results of the comparison of the average of the effect of solubility on grain yield showed that Zinc + Zinc solution had the highest seed yield with an average of 3526 kg. ha-1.
