Micro-nutrient enrichment through foliar application at different stages of chickpea

. Fakhar ul Islam and Asim Muhammad


Abstract

Low zinc and iron availability due to alkaline soil, having high pH limiting crop production. Field experiment was conducted at the farmer field in Karak, for two consecutive years, 2016-17 and 2017-18. The experiments were laid out in RCB design having three replications. The factors included iron levels (1.5, 2, 2.5 kg ha-1), zinc (1, 2, 3 kg ha-1) applied at two growth stages vegetative (V3) and reproductive stages (R3) applied on Fakhr-e-Thal chickpea. The results showed that the iron applied at 2.5 kg ha-1 significantly increased grains pod-1, grains weight, iron content, zinc content, grain and biological yield. The application of zinc applied at the rate of 3 kg ha-1 increased grains weight, grain yield, biological yield, harvest index, iron content and zinc content. The micronutrients (iron and zinc) applied at the reproductive stage improved iron content, zinc content, biological yield.
