Abstract
A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to study the ”Effect of Nitrogen Rates and Foliar Spray of Urea Application and Nano Urea on Yield and Economics of rabi Maize (Zea mays L.)”effect of three nitrogen rates (50%, 75% and 100% RDN ) and three foliar spray of urea viz 20000 PPM (2%) and nano urea viz 2000 PPM (2 ml/L) and 4000 PPM (4ml/L) application on yield and economics of rabi maize (Zea mays L.). The soil of experimental plot was sandy loam texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225kg/ha), available P (19.50) kg/ha) and available K (92 kg/ha). The experiment consists of 10 treatment, each being replicated thrice and laid out in Randomized Block Design. The results of present investigation revealed that the highest Grain yield (6.41 t/ha), Stover yield (8.65 t/ha), Harvest Index (42.58), Maximum gross return (INR 1,28266.67), Net return (81,682.75) and B:C ration (1.75) under 100% RDN +4000ppm (4 ml/l) spray of nano urea.
