The interaction effect of different dose of sulphur and zinc with optimum dose of N, P and different dose of organic manure on growth and productivity of mustard (Brassica compestris) were studied during October 2006 to March 2008. The level of S and Zn were employed at 0, 20, 40 and 60 kg S/ha⁻¹, 0.50, 1.0, 2.0 kg Zn/ha⁻¹ and 0, 10, 15, 20 Q/ha⁻¹ organic manure respectively. The result indicated that growth and productivity increase with increasing level of S and Zn. Application of the S and Zn were highly influenced with the application of 60 kg S/ha⁻¹ in the combination. The root length, shoot length, number of leaf/plant, number of branch/plant and crop growth rate was much influenced on these combination. The productivity such as biomass production, number of capsule, seed output and reproductive capacity with grain biological yield also increased with increasing level of S and Zn at S₃ and Zn₃ levels.
