Abstract
A field experiment was conducted to evaluate the interactive effects of sulphur, boron, and organic manure on the growth, yield, and soil fertility of mustard (Brassica juncea L.) under Inceptisol. The experiment comprised eleven treatments with varied combinations of RDF, sulphur, boron, and FYM. Results revealed that the combined application of 75% RDF + FYM @ 6 t ha{¹ + B @ 3 kg ha{¹ + S @ 30 kg ha{¹ (T10) significantly enhanced plant height, seed yield (18.05 and 18.94 q ha{¹), and harvest index (29.07 and 31.02%) over control and RDF alone. The improvement was attributed to synergistic nutrient interaction and improved soil fertility status. The study concludes that integrated nutrient management involving organic manure with balanced sulphur and boron supplementation optimizes mustard productivity and sustains soil health in Inceptisol soils.
