Abstract

The present investigation was conducted to evaluate the effect of different doses and sources of sulphur on growth, yield and quality of mustard (Brassica juncea L.). The experiment was framed with twelve treatment combinations and triplicate replications in factorial randomized block design comprising three different sources of sulphur viz., Gypsum, Iron pyrite and Bentonite whereas different sulphur doses such as 0, 20, 40 and 60 kg S ha-1. Growth parameters like plant height, leaf area index and dry matter production per plant was observed highest with Bentonite S. They increased with increasing S doses up to 40 kg ha-1 except dry matter production per plant which recorded maximum value at 60 kg S ha-1. Highest seed yield (15.4 q ha-1) of mustard was noted from Bentonite S. The increasing S dose up to 40 kg ha-1 increased seed yield (16.9 q ha-1) of mustard. Different doses of sulphur caused significant variations in stover yield of crop. Stover yield increased with increasing doses of sulphur registering the maximum stover yield (42.3 q ha-1). Highest oil content (40.5%) was noted from Bentonite S. Oil content in seed increased with increasing S dose up to 60 kg ha-1 (42.4%). The optimum dose of sulphur was computed 49.6 kg ha-1 for Bentonite in mustard followed by 53.4 kg ha-1 for iron pyrite and 57.1 kg ha-1 for gypsum.
