Three Indian mustard [Brassica juncea (L.) Czernj. & Crosson] cultivars (‘Varuna’, ‘Vardan’ and ‘Narendra Rai 1,) with 3 sulphur sources (gypsum, elemental sulphur and pyrite) and 4 sulphur levels (0, 20, 40 and 60 kg/ha) were tested during the winter (rabi) season of 1996–97 and 1997–98. ‘Narendra Rai 1’ and ‘Varuna’ gave higher plant height, branches/plant, siliquae/plant, seeds/siliqua, 1,000-grain weight and harvest index and resulted significantly higher seed and stover yields, sulphur uptake, oil and protein contents than ‘Vardan’, though the former two were at par during both the years. However, the sources of sulphur did not influence the growth yield attributes and yields as well as quality of Indian mustard. The application of 40 and 60 kg S/ha being at par with each other gave significantly higher yield and quality (protein and oil contents in seed) over 20 kg and no-sulphur application. The growth and yield-attributing characters showed also similar trend. On the basis of economics, ‘Narendra Rai 1’ fertilized with 40 kg S/ha either through gypsum or pyrite was found most profitable.
