Effect of Nano Urea and Zinc on Growth and Yield of Baby Corn (Zea mays L.) under Prayagraj Condition

Abstract

A field experiment was conducted at the Crop Research Farm (CRF), Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Kharif season 2022. The experiment comprised of ten treatments of different combinations of Nanourea and Zinc nutrient management replicated thrice in a Randomized Block Design. The main objective of the experiment was to evaluate the “Response of Nano urea and Zinc on growth and yield of Baby corn (Zea mays L.)” Prayagraj condition. The three level of nano urea levels N1- 1 ml/l foliar spray nano urea, N2 -2 ml/l foliar spray nano urea and N3 - 3 ml/l foliar spray nano urea. Where-as three levels of zinc include like Z1- 20 kg/ha zinc, Z2- 25 kg/ha zinc and Z3- 30 kg/ha zinc. From the present investigation it may be concluded that the profitable production of baby corn can be secured by ZnSO4 30 kg/ha + Nanourea 3 ml/lt. (T9). Highest Gross returns (92087.17 ₹/ha), Net returns (61352.17 ₹/ha) and B:C ratio (2.00) were recorded significantly high with the application of ZnSO4 30 kg/ha + Nano urea 3 ml/lt.
