Abstract
To evaluate effects of micronutrients on some traits of Zea mays L. cv. Jeta an experiment was conducted in factorial arrangement, on the basis of randomized complete block design with three replications during growing season of 2008. Treatments were six types of micronutrients (control, ZnSO 4 , MnSO 4 , H 3 BO 3 , FeSO 4 and complete micronutrients) and three methods of application (soil application, seed coating and foliar application). Analysis of data showed that in three methods of micronutrient application, only foliar application had net effect on increasing traits. Applying any microelements in any methods increased net assimilation rate (NAR) and crop growth rate (CGR) of corn. Seed coating was superior to others in early season but nutrient amounts were little, so they were used or fixed by plant or soil, then its effect began to decrease before mid season. Soil application of any microelement improved NAR and CGR of corn, but fixation of H 3 BO 3 and ZnSO 4 at mid season decreased NAR and CGR. Foliar application of micronutrients covered all needs of corn and led it to have the best action on NAR and CGR. Highest yields (16,040 kg.ha -1 ) were obtained when leaves were sprayed with ZnSO 4 . The 1000 kernel weight of corn was 374.6 g with foliar application of ZnSO 4 . Kernel weight increased 35.47% when ZnSO 4 was used.
