Effect of Sulphur and Foliar Application of Iron (FeSO4) on Growth and Yield of Groundnut

The field experiment was carried out on the groundnut crop during the Kharif season of 2022 at the agricultural research farm of the department of agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The treatment included a control plot and 3 doses of foliar sprays for iron (0.5, 0.75, and 1%) and sulphur (20, 40, and 60 kg). Ten treatments and three replications were included in the experiment's Randomized Block Design (RBD) design. A significant increase in plant height (53.60 cm) at 80 DAS, dry weight (37.73 g), kernel yield (2.47 t/ha), gross return (157520.00 INR/ha), net return (106768.40 INR/ha), and B:C ratio (2.10) were seen following the application of sulphur at a rate of 60 kg/ha plus 1% FeSO4.
