Abstract:
A field experiment was carried out during rabi 2020 at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur to study the Response of Indian Mustard {Brassica juncea (L.) Czern and Coss} to various sources and levels of Sulphur on nutrient content or uptake. Experiment consisted of 16 treatment combinations comprised of 5 sulphur levels (20, 30, 40, 50 and 60 kg sulphur ha^-1), 3 sulphur sources (Gypsum, Bentonite sulphur and Elemental sulphur) and one absolute control. Result revealed that application of sulphur significantly increased seed yield, straw yield and biological yield by 28.27, 40.03 and 37.06 per cent over control. Application of 40 kg sulphur ha^-1 increased seed yield by 16.67 and 11.12 per cent, respectively. Sulphur application significantly increased N, P, K and S content in seed and straw by 7.19 and 5.00, 5.42 and 12.16, 6.18 and 1.99, 8.77 and 8.57 per cent respectively over control. Application of 40 kg sulphur ha^-1 significantly influenced N, P, K and S content and uptake by seed and straw over 20 and 30 kg sulphur ha^-1. Application of 40 kg sulphur ha^-1 was found statically at par with 50 and 60 kg sulphur ha^-1 in case of seed yield, nutrient content and uptake by seed and straw. Sources of sulphur significantly influence N, P, K and S uptake by plant by 5.93, 6.86, 6.23 and 7.83 per cent respectively over control.
