Influence of different levels of N application and foliar spray of zinc on growth and economics of hybrid maize

Abstract

A field experiment was conducted during kharif seasons of 2020-21and 2021-22on clayey soil at MGU, Sehore (Madhya Pradesh) to study the effect of different levels of N and foliar spray of zinc on plant height and economics. Results revealed that significantly highest plant height at 90 DAS, net return and B:C ratio was recorded with the application of Nitrogen-150 kg/ha + 1.5% foliar spray of ZnSO4 followed by application of nitrogen-150 kg/ha + 1.0% foliar spray of ZnSO4, nitrogen-150 kg/ha + 0.5% foliar spray of ZnSO4, nitrogen-120 kg/ha + 1.5% foliar spray of ZnSO4, nitrogen-120 kg/ha + 1.0% foliar spray of ZnSO4. The lower plant height at 90 DAS, net return and B:C ratio followed by application of nitrogen-00 kg/ha + 0.0% foliar spray of ZnSO4 was recorded with the application of control.
