Abstract
The field experiment was conducted during kharif season of 2022 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (UP) India. To study the response of sulfur and silicon on growth and yield of Rice. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%). Findings showed that the higher plant height (117.68 cm), higher number of tillers/hill (14.75), higher plant dry weight (102.23 g/plant), higher crop growth rate (76.8 g/m2/day), number of panicles/hill (12.01), higher number of grains/panicle (140.05), higher 1000 seed weight (23.91 gm), higher grain yield (6.87 t/ha) and higher straw yield (14.53 t/ha) were significantly influenced with application of Sulfur 30 kg/ha + Silicon 120 kg/ha. Higher gross return (INR 1,73,066.00/ha), higher net return (INR 1,24,238.00/ha) and higher B:C ratio (2.54) were also recorded in treatment 9 (Sulfur 30 kg/ha + Silicon 120 kg/ha).
