Sulphur Nutrition on Productivity of Kharif Sorghum (Sorghum bicolar)

The field experiment was conducted at UAS, Dharwad, India. Among the sources of sulphur, the application of bentonite recorded significantly higher grain yield (44.67 q ha-1), dry fodder yield (9.06 t ha-1), crude protein content (8.3 %) and sulphur uptake (20.73 kg ha-1) when compared to the application of gypsum and single super phosphate. It also recorded significantly higher gross returns (Rs.84990 ha-1), net returns (Rs.42270 ha-1) and B:C ratio (1.99). Among levels of sulphur, the application of 30 kg S ha-1 recorded significantly higher grain yield (44.91 q ha-1), dry fodder yield (9.29 t ha-1), crude protein content (8.3%) and sulphur uptake (20.14 kg ha-1). It also recorded significantly higher gross returns (Rs. 85640 ha-1), net returns (Rs. 43440 ha-1) and B:C ratio (2.03) when compared to application of 10 and 20 kg S ha-1.
