摘要

In order to assessment of zinc application effect in different growth stages on yield and yield components ofsweet corn (var. Chalenger), the experiment was performed in 2013 cultivation season at Agriculture College ofIslamic Azad University, Tabriz Branch in form of randomized complete block design with three replications.Studied treatments were included: control: non-use of zinc sulfate, (A) usage of zinc sulfate in soil, foliarapplication in: (B) stage of plants with 6-8 leaves, (C) tasselling, (D) grain filling stage, (B+C) stages of plantswith 6-8 leaves and tasseling, (B+D) stages of plants with 6-8 leaves and grain filling, (B+C+D) stages of plantswith 6-8 leaves, tasseling and grain filling, (A+B) soil using and foliar application at stages of plants with 6-8leaves, (A+C) soil using and foliar application at stages of tasseling, (A+D) soil using and foliar application atstages of grain filling, (A+B+C+D) soil using and foliar application at stages of plants with 6-8 leaves, tasselingand grain filling in form of 5 per thousand using hand sprayer for foliar application and 25 kg/ha Zinc Sulfate forsoil using. In this study the traits of ear fresh weight, ear yield, grain fresh weight per ear, grain yield, number ofgrain per ear, ear weight and 100 kernels weight were evaluated. The results demonstrated that zinc sulphate soilusing and foliar application in 6-8 leaves, tasseling and grain filling stages (A+B+C+D), soil using and foliarapplication in grain filling stage (A+D) increased grain yield about 34.33g. and 32.74g., respectively; ascompared with control. These treatments increased grain yield about 24.24g. and 22.42g., respectively incomparison with control treatment. So, revenue increment per hectare by foliar application of this element canbe significant.
