Abstract
The experiment was conducted during Zaid season 2021 at KVK, SHUATS, Prayagraj (U.P.) to study the influence of potassium and sulphur on growth and yield of greengram. The treatments consist of potassium 15, 25, 35 kg/ha and sulphur 10, 20, 30 kg/ha. The result reported that application of potassium 35 kg/ha + sulphur 30 kg/ha (Treatment 9) recorded significantly highest Plant height (45.77 cm), maximum number of branches (6.50), maximum number of nodules (21.73), maximum plant dry weight (9.66 g). It is also observed that the maximum grain yield (1,109.67 kg/ha) and stover yield (2,431.00 kg/ha) was obtained with the application of potassium 35 kg/ha along with sulphur 30 kg/ha. It was concluded that application of potassium and sulphur performs positively and improves growth and yield parameters of Greengram.
