Impact of sulphur on Indian mustard (brassica Juncea L.) with different doses and sources

The experiment was laid out during Rabi season of 2013 and 2014 in open field at research farm, Baba Raghav Das Post Graduate College, Deoria (U.P.) with the main objective of experiment to know the impact of sulphur on Indian mustard (Brassica juncea L.) with different doses and sources. Results showed that most of the yield attributes were significantly influenced by different doses of sulphur. All these attributes were estimated during the entire period of maturity and harvest. The yield and yield contributing characters were found to increase with the increasing levels of sulphur up to 45kg sulphur per hectare. Yield attributes, such as number of siliquae per plant, seeds per sthqua, 1000-seed weight and seed yield per plant were found maximum under 45kg sulphur per hectare. Similarly, increasing the sulphur dose up to 45kg per hectare improved seed yield, straw yield, harvest index and oil content in mustard. Also sulphur application enhanced seed oil content at this dose. Application of sulphur through gypsum increase in yield attributes, seed and straw yield as well as biological yield. All the sources of sulphur did not found significant effect on yield attributes and yield of mustard. Among sources of sulphur through gypsum gave significant superiority over others.
