A research was conducted during summer season of 2022 at crop research farm (CRF), Department of Agronomy, SHAUTS, prayagraj (U.P), to evaluate the influence of potassium and sulphur on growth and yield of summer sunflower. The treatments consisted of 3 levels of Potassium (30,40,50 Kg/ha) and Sulphur as (10,20,30 Kg/ha) and a control. The experiment was laid out in randomized block design (RBD) with 10 treatments and replicated thrice. The results showed that Application of 50 kg potassium soil application with combination of 30 kg sulphur as soil application recorded highest plant height (125.4 cm), plant dry weight (15.0 g/plant), and the yield attributes namely seeds per capitulum (332.4) Test weight (33.7 g), seed yield (1463.44 kg/ha), stover yield (3211.6 kg/ha), harvest index (31.3 %) and highest benefit - cost ratio (1.94).
