A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P). To determine the “Influence of phosphorus and sulphur on growth and yield of sunflower (Helianthus annuus L.)”, The results showed that treatment 9 [Phosphorus (60 kg/ha) + Sulphur 25 kg/ha] recorded significantly higher plant height (123.10 cm), higher plant dry weight (91.03 g). Where as, higher number of seeds/capitulum (412.00), higher test weight (50.50 g), higher seed yield (1.25 t/ha), higher Stalk yield (3.44 t/ha), higher oil content (40.37%), was recorded in treatment 9 [Phosphorus (60 kg/ha) + Sulphur 25 kg/ha). Similarly, maximum gross returns (83,440.00 INR/ha), higher net returns (55,851.25 INR/ha), and highest benefit cost ratio (2.02) was also recorded in treatment 9 [Phosphorus (60kg/ha) +Sulphur (25kg/ha)], as compared to other treatments.
