EFFECT OF SULFUR AND NITROGEN ON YIELD ATTRIBUTES AND SEED YIELD OF INDIAN MUSTARD (BRASSICA-JUNCEA) ON VERTISOL

A field experiment was conducted during the the winters of 1987-88 and 1988-89 to study the effect of sulphur and nitrogen on yield attribut es and seed yield of Indian mustard [Brassica juncea (L.) Czernj. & Co sson] on Vertisol of Udaipur. N @ 60 kg/ha significantly improved the yield parameters, viz. siliquae/plant and seed yield/plant and 1,000-s eed weight during both the years and seeds/siliqua during 1987-88. Thi s level of N was also significantly superior to the other levels for s eed yield during both the years as well as in pooled results. All the yield characters and seed yield showed a significant increase up to 10 0 kg S/ha. However, mode of sulphur application did not show significa nt effect on yield attributes and seed yield.
