In order to investigate the effects of foliar application of micronutrients, zinc, boron and copper both individually and in combination on growth indicators and yield of sweet corn (Zea mays L. var. Samyra), this experiment was conducted in randomized complete block design with three replications in research farm of the Faculty of Agricultural Sciences, University of Guilan Iran in Spring 2015.Foliar treatments included: control, zinc (concentration 2 parts per thousand from zinc sulphate),boron(concentration 2 parts per thousand from boric acid),copper(concentration 1 parts per thousand from copper sulphate),zinc + born, zinc + copper, boron + copper, and zinc + boron + copper. The results showed that foliar application of micronutrients was effective in increasing crop growth rate, leaf area index and total dry weight and in all of traits combined three elements foliar micronutrient treatment was superior compared to the other treatments, Such that it increased the maximum crop growth rate, leaf area index and total dry weight in this treatment by 49.2, 48.5 and 43.7%, respectively. In this study, the highest dry forage yield and grain yield were 2286 and 2194kg ha-1 respectively, also maximum grain yield canned was obtained 6454 kg ha-1 from three treatments of foliar micronutrient. According to the results of this experiment it seemed that foliar application of micronutrients, zinc, boron and copper was a useful approach for increasing sweet corn seed yield in conditions similar to this experiment.
