Abstract
A field experiment was conducted at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during the Zaid season of 2022 on sandy loam soil. The experiment was laid out in Randomized Block Design, consisting of three levels of sulphur (10 kg/ha, 15 kg/ha, 25 kg/ha) and three levels of iron as a foliar spray (1500, 2000, 2500 mg/kg). The maize variety Kanchan was sown in April 2022. The results of the experiment revealed that the application of 25 kg/ha of sulphur along with 2500 mg/kg of iron significantly increased the growth parameters viz., plant height (196.4 cm), and dry weight (83.03 g/plant), whereas, application of 25 kg/ha of sulphur and iron at 2500 mg/kg also showed a positive effect on economics viz., gross returns (121644.00 INR/ha), net returns (84843.00 INR/ha) and B: C (1:2.30).
