Effect of Various Sources and Levels of Sulphur on Growth, Dry Matter Production and Nutrient Uptake of Indian Mustard (Brassica juncea L.)

A field experiment was conducted to assess the response of Indian mustard to various sources and levels of sulphur during rabi season of 2021 at College Farm, College of Agriculture, PJTSAU, Rajendranagar, Hyderabad. The experiment was carried out with three sources of sulphur (ammonium sulphate, gypsum and bentonite sulphur) and three levels of sulphur (20, 40 and 60 kg S ha-1) with one additional treatment (control i.e., 0 kg S ha-1) in factorial concept and replicated thrice. Significant crop response was observed for plant height, leaf area index and dry matter production with application of ammonium sulphate among all the three sources. Among the levels of sulphur, the higher values of plant height, leaf area index and dry matter recorded on application of 60 kg S ha-1, which showed parity with 40 kg S ha-1. The similar trend was also noticed for seed yield and nutrient uptake (N and S).
