Effect of Zinc and Gypsum on Growth, Yield and Economics of Groundnut (Arachis hypogaea L.)

The experiment entitled was “Effect of zinc and gypsum on growth and yield of Groundnut (Arachis hypogaea L.)” conducted during kharif, (2021) at crop research farm, Department of Agronomy, SHUATS, Prayagraj (U. P) on sandy loam soil. the experiment was laid out in Randomized Block Design it consist of 9 Treatments with 3 Replication comprising three levels of zinc (0.25%, 0.5%, 0.75%) and three levels of zinc (0.25%, 0.5%, 0.75%) and three levels gypsum (300 kg/ha, 400 kg/ha, 500 kg/ha) the significantly highest result showed in (Treatment 9) 0.75% zinc foliar spray + 500 kg/ha Gypsum) growth and yield attributing character viz., plant height (58.33 cm), nodules/plant (106.88), dry weight (39.3 g), pod/plant (19.3), kernel/pod (2.6), seed index (41.00), seed yield (2917.00 kg/ha), haulm yield (4453.3 kg/ha). The gross returns (1,25,431.00 INR/ha) net returns (83355.60 INR/ha) and B:C ratio (1.98) are also recorded numerically highest with the (Treatment 9) application of 0.75% Zinc foliar spray + 500 kg/ha gypsum.
