Sulphur plays an important role in the plant’s metabolism, and required for amino acids, proteins and photosynthesis. The intensification of agriculture with high yielding crop varieties and multiple cropping coupled with the use of high analysis sulphur free fertilisers along with restricted use of organic manures have accrued in depletion of the soil sulphur reserve. The crops which produce higher biomass and the quality such as sugarcane removes higher amount of sulphur from soil which necessitates the replenishment. Therefore, A field experiment was conducted at sugarcane Research Station, Vuyyuru to know the optimum dose and proper source of sulphur for sugarcane plant crop. Three levels of sulphur viz; 30, 60 and 90 kg/ha along with recommended doses of nitrogen, phosphorus and potassium were applied through two sources such as gypsum and elemental sulphur. These were tested against no sulphur treatment. Thus seven treatments were replicated thrice in RBD design with the sugarc

Sulphur, gypsum, elemental sulphur, sugarcane, cane yield, CCS yield, juice sucrose, nutrient uptake.

Finally to summarise, the shoot population at different stages of crop growth, cane yield, CCS yield, quality, nutrient uptake and nutrient availability in post harvest soils were increased with increase in the dose of sulphur application from no sulphur to 90 kg/ha. Among the sources, gypsum recorded highest yields, quality and nutrient uptake and elemental sulphur was on par with it. However, gypsum is economical in use than elemental sulphur. Hence, it can be concluded that 90 kg sulphur per hectare is the optimum dose and gypsum is the better source for sugarcane plant crop for getting the improved cane, CCS yields, quality, nutrient uptake and nutrient availability of nitrogen, phosphorus and potassium in post harvest soils
