The effects of Zinc and Manganese on yield and yield components winter canola varieties in Gilan

In order to study the effects of Zinc and Manganese on yield and yield components winter canola varieties in Gilan, an experiment was carried out in Rice Research Institute of Iran, Rasht during 2009. The experiment was arranged in a randomized complete block design as factorial with three replications. In this experiment, factors include the use of micronutrient fertilizers in four levels (zinc sulfate, manganese sulfate, zinc sulfate and manganese sulfate mixture and their unapplication) and Varieties include in three levels Hyola 401, Hyola 308 and RGS003 were considered. The results showed that the effect of micronutrient fertilizers and variety on plant height, number of secondary branches per plant, number of pods per main stem, number of pods per secondary stems, number of seed per pod of main stem, number of seed per pod of secondary stems, seed yield and biologic yieldwere Significant. interaction the experimental treatments only on number of pods per secondary stems and number of seed per pod of main stem were Significant. The results showed that applying treatment Zinc Sulfate and Manganese Sulfate together in Hyola401 variety with average 74/00 pod and 26/20 seed have to most number of pods per secondary stems and number of seed per pod of main stem.
