Optimizing Biofortification Of Zinc By Fertigation And Foliar Application In Barley Under Calcareous Soil Condition

Abstract

Zinc is known as the “metal of life” and its inadequacy effects the plant in various forms. Zinc sulfate helps to prevent low yields, spotted leaves and stunted growth. Barley such as hordeum vulgare valgare L is view of the familiar earliest grains which has been developed from the food grain to support and malting grain. Air dried soil was taken and passing it through the sieve of 2mm. To store them pouring the soil into the plastic pot. To check the performance of optimizing biofortification of zinc in calcareous soil by the process of foliar application of zinc sulphate and fertigation in barley, consideration is taken place. An experimental study was performed in the laboratory of Minhaj University Lahore (MUL) during the Rabi season of 2020-2021 under appropriate condition. The investigative study comprises of three replicates each with nine treatments occur in a completely randomized design (CRD). Zinc was applied through fertigation and foliar application at a distinct rate (zer0,10,20,30). The potted experiment showed enhanced effect with the Zinc fertigation and foliar application in the plant weight and plant height as highest plant weight of fertilized treatments at the rate of Zn 10 was 2.227 and it is followed by treatment at the rate of Zn 30 was 1.704 and the lowest value showed at the rate of Zn 30 was 1.197. Moreover, out of fertigation and foliar application process of fertilized treatment of Zn by Zinc use efficiency shows the highest value by the treatment at the rate of Zn 10 was 45.04 and at the rate of Zn 30 was 44.46 which is followed by the treatment at the rate of Zn 30 was 36.61. So, it is cleared from the results that fertigation and foliar application process is more appropriate for optimizing the biofortification of zinc in barley in a calcareous soil by using zinc sulphate.
