Nutrient management for enhancing the productivity of Indian mustard (Brassica juncea)

A field experiment was conducted on clay loam soil in rabi seasons of 2011, 2012 and 2013 with 5 nutrient management practices in Indian mustard for sustained crop and soil productivity in vertisols of irrigated condition at farmer's field in Kota, Rajasthan. Production (17.75 kg ha⁻¹ d⁻¹) and economics efficiency (Rs. 429 ha⁻¹ d⁻¹) was significantly higher in treatment T₂ (RDF + 40 kg S ha⁻¹ by bentonite sulphur) over T (RDF + without sulphur) and farmer practices and at par with T₅ (RDF + 40 kg S ha⁻¹ by elemental sulphur) and T₁ (RDF + 40 kg S ha⁻¹ by gypsum)
