Abstract

The experiment consisted of two levels of Nitrogen at 120 and 150 kg ha -1 , basal application of Boron (5 kg ha -1 ) and Zinc (25 kg ha -1 ), without and with combination of foliar application of Boron (0.3% at 15 DAS) and Zinc (0.25% at 30 DAS). There were 12 treatments which were replicated thrice and laid out in a Randomized Block Design. Higher plant height, maximum plant dry weight, crop growth rate, more number of cobs plant -1 , more number of grains cob -1 , test weight and grain yield was recorded with (Treatment 12) N at 150 kg ha -1 (along with P & K each at 75 & 60 kg ha -1 ) in combination with Zinc at 25 kg ha -1 as basal and Boron at 0.3% as foliar spray. This treatment also recorded highest gross return, net return and benefit cost ratio.
