In Prayagraj, Uttar Pradesh, at the Crop Research Farm of the Naini Agriculture Institute of the Sam Higginbottom University of Agriculture, Technology, and Sciences, Department of Agronomy, during the Kharif season of 2022, the field experiment titled "Response of zinc and nano urea on growth and yield of maize (Zea mays L.)" was carried out. The results showed that the application of Zinc 30 kg/ha + Nano urea 4 ml/l considerably increased the growth parameters viz. plant height (195.01 cm), dry weight (90.62 g), number of grains per cob (476.79), cob length (21.2 cm), grain yield (4.33 t/ha), and stover yield (6.65 t/ha).
