Abstract:
A field experiment was conducted to arrive the optimum dose of sulphur for sugarcane ratoon crop at sugarcane Research Station, Vuyyuru. Sulphur in the form of gypsum and elemental sulphur was applied in three levels viz; 30, 60 and 90 kg/ha along with recommended doses of nitrogen, phosphorus and potassium and were tested against no sulphur applied treatment. Thus seven treatments were replicated thrice in RBD design with the sugarcane variety 99 V 30. The treatments include T1: Recommended doses of NPK only (RDF), T2: RDF + 30 kg of ‘S’ per ha. Through elemental Sulphur, T3: RDF + 60 kg of ‘S’ per ha. Through elemental Sulphur, T4: RDF + 90 kg of ‘S’ per ha. Through elemental Sulphur, T5: RDF + 30 kg of ‘S’ per ha. Through Gypsum, T6: RDF + 60 kg of ‘S’ per ha. Through Gypsum and T7: RDF + 90 kg of ‘S’ per ha. Through Gypsum. Application of sulphur resulted with the increase in shoot population at different stages of crop growth, cane yield, commercial cane sugar yield and nutrient uptake of nitrogen, phosphorus and potassium by sugarcane ratoon crop and were more at 90 kg sulphur per hectare. Among the sources tried, gypsum recorded highest cane and CCS yields and nutrient uptake and elemental sulphur was also significantly on par with gypsum. As the gypsum is economical in use than elemental sulphur, application of sulphur @ 90 kg/ha in the form of gypsum along with the recommended doses of nitrogen, phosphorus and potassium can be recommended for getting highest cane and CCS yields and nutrients uptake for ratoon crop of sugarcane.
