Influence of Foliar Application of Zinc on Growth and Yield of Pearl Millet (Pennisetum glaucum L.) Varieties

A field investigation was conducted in Kharif (2022), at a Crop Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). To study the “ Influence of foliar application of zinc on growth and yield of pearl millet (Pennisetum glaucum L.) varieties.” An experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. The treatments consist of three different pearl millet varieties (Kaveri super boss, Nutra pearl, Nandi-75) and foliar application of Zinc on 25 DAS and 25 and 50 DAS respectively. The experimental results revealed that significantly higher values of growth parameters viz., plant height (191. 87 cm), dry weight accumulation (58.75 g/plant), CGR (10.55 g/m2/day) and yield attributes viz., ear head length (19.50 cm), grains/ear head (1203.60), test weight (10.02 g), grain yield (1.37 t/ha), straw yield (1.70 t/ha) were recorded maximum in treatment (Kaveri Super Boss + ZnSO4 0.5% (at 25 and 50 DAS) T3. These parameters were significantly influenced by increasing the foliar spray of ZnSO4.
