Foliar Application of Micronutrients Enhances Wheat Growth, Yield and Related Attributes

Abstract

Wheat is one of the most essential foods in the world. To increase its productivity, nutrient man-agement is one of the most important factors. To assess the possible role of micronutrients in im-proving wheat yield, an experiment was conducted to evaluate the wheat performance by foliar application of micronutrients. Treatments consist of T 1 = No spray, T 2 = Spraying plants with tube well water (control), T 3 = Spraying plants with 1.6 kg FeSO 4 /100 L water/acre, T 4 = Spraying plants with 3 kg ZnSO 4 (21%)/100 L water/acre, T 5 = Spraying plants with 1 kg MnSO 4 /100 L wa-ter/acre, T 6 = Spraying plants with (FeSO 4 + MnSO 4), T 7 = Spraying plants with (FeSO 4 + ZnSO 4), T 8 = Spraying plants with (ZnSO 4 + MnSO 4), and T 9 = Spraying plants with (FeSO 4 + ZnSO 4 + MnSO 4). Results showed that foliar application of micronutrients substantially improved plant height, spike length cm, spikelets/spike, grains/spike, test weight, Tillers m −2 , grain and biological as well as harvest index of wheat. Among treatments, foliar application of FeSO 4 + ZnSO 4 + MnSO 4 remained comparatively better regarding yield related attributes of wheat.
