EFFECT OF SOURCE LEVEL AND METHOD OF APPLICATION OF SULFUR ON INDIAN MUSTARD (BRASSICA-JUNCEA)

Application of sulphur through gypsum significantly increased the seed yield, oil yield and number of siliquae/plant in indian mustard [Bras sica juncea (L.) Czernj. & Cosson] compared with pyrite. An increase i n S level significantly increased the seed yield, oil yield and number of siliquae/plant. The 1 000-seed weight and oil content were increas ed compared with the control but there was no significant difference i n yield between 25 and 50 kg S/ha. The method of S application had no significant influence on yield but its application at sowing significa ntly increased the number of siliquae/plant. Dry-forage yield of subse quent cowpea. [Vigna unguiculata (L.) Walp.] crop was not influenced b y the source, level and method of S application.
