Abstract: A field experiment was conducted during Kharif 2018 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P.). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.7), low in organic carbon (0.35%), available N (230 kg ha^-1), available P (20 kg ha^-1) and available K (189 kg ha^-1). The experiment consist of 4 levels of Zinc (0, 5, 10, 15 ha^-1) and Boron applied as foliar at (0.0%, 0.3%, 0.5% ha^-1).There were 12 treatments replicated thrice and lead out in a random block design. Application of 15 kg Zn ha ha^-1 applied as Basel in combination with Boron at 5% recorded maximum no. of grains cob^-1 (647.80), test weight (25.14)and green cob yield (5.94 t).Hence gross return (127956.00 INR), net return(71508.00 INR)and B:C ratio (1.26) was also recorded in the aforesaid treatment.
