Abstract
A field experiment was laid out at Palampur during kharif 2015 to study the response of soybean to levels and sources of sulphur under mid - hill conditions of Himachal Pradesh. The treatments comprising of all possible combinations of three levels of sulphur viz. 20, 40 and 60 kg S/ha and four sources of sulphur viz. SSP, Gypsum, Elemental sulphur and Epsom salt along with absolute control and 100% NPK + 10 t FYM/ha were tested in Randomized Block Design (RBD) replicated three times. The result revealed that growth, yield attributes, seed and straw yield of soybean increased with the application of S upto 40 kg/ha. Higher dose of sulphur could not significantly affect growth, yield attributes and seed and straw yield of soybean. Among the sources of sulphur gypsum gave the better response in terms of growth, yield attributes and seed and straw yield of soybean over the other sources. Nutrient (N, P, K and S) uptake by the crop increased with increase in sulphur 40 kg S/ha. Gypsum gave higher uptake of NPK and S over other sources of sulphur. Gross returns (78959 ₹/ha), net returns (37360 ₹/ha) and B: C (1.91) ratio was significantly higher at 40 kg S/ha. Gypsum gave highest gross returns (75086 ₹/ha), net returns (43998 ₹/ha) and B: C ratio (2.11).
