Abstract
Department of Soil Science and Agricultural Chemistry, Orissa University of Agriculture and Technology, Bhubaneswar-751 003, Odisha, India E-mail: saren.soil@yahoo.co.in Department of Agricultural Chemistry and Soil Science, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur-741 252, Nadia, West Bengal, India Manuscript received 09 January 2018, revised 06 March 2018, accepted 21 March 2018 A field experiment was conducted to study the changes in different fractions of sulphur in soils grown with rapeseed (cv. Binay) crop. Sulphur was added in two levels along with recommended doses of NPK, farm yard manure (FYM) and sulphur oxidising bacteria (SOB) (Thiobacillus ferroxidans) as different treatment combinations to study the changes in different fractions of sulphur at various growth stages of rapeseed. Results show that the stover yield of rapeseed was increased with higher dose of FYM but lower dose of S, while the highest seed yield was obtained with higher dose of S and lower dose of FYM along with the SOB and recommended doses of N, P and K. Sulphate sulphur, adsorbed sulphur, organic sulphur and total sulphur were found to be decreased with increase in the period of crop growth maintaining a dynamic equilibrium. The decrease in different fractions of sulphur is due to its utilization by the growing crop. Different fractions of sulphur in soil showed an interrelationship within themselves
