Abstract
The field experiment entitled “response of sulphur and foliar application of nano urea on growth and yield of sunflower” was conducted during Summer, 2022 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The result showed that maximum diameter of capitulum (14.85 cm), number of seeds/capitulum (453.67), test weight (44.58 g), seed yield (1.70 t/ha), oil content (37.73 %) and B:C ratio (2.54) were obtained by the application of Sulphur at the rate 40 kg/ha along with Nano urea (3ml/l) in treatment 8 whereas higher plant height (118.83 cm), plant dry weight (70.08 g) and stover yield (3.36 t/ha) were obtained by the application of Sulphur at the rate 40 kg/ha along with Nano urea 4ml/l in treatment 9.
