Influence of Potassium and Sulphur on Yield, Economics and Quality of Summer Sunflower

The experiment was completed activity during summertime season of 2022 at crop research farm (CRF), Department of Agronomy, SHAUTS, Prayagraj (U.P), to judge the influence of potassium and sulphur rates on growth and yield of vacation sunflower. The treatments incorporated 3 levels of Potassium (30,40,50 kg/ha) and Sulphur (10,20,30 Kg/ha) and a control. The experiment secondhand a Randomized Complete Block Design (RCBD) with ten situations that were replicated three periods. The findings told that use of 50 kg potassium with consolidation of 30 kg sulphur as soil application written topmost yield attributes namely children per capitulum (332.4) Test burden (33.7 g), source yield (1,463.44 kg/ha), stover yield (3,211.6 kg/ha), harvest index (31.3%) and oil content(41.8 %). Maximum gross returns (98,050.48 (Indian rupee) INR/ha), net returns (64,665.51 (Indian rupee) INR/ha) and maximal benefit - cost ratio (1.94) was in the direction of treatment (T9) accompanying the use of 50 kg potassium soil application accompanying combination of 30 kg sulphur as soil request.
