Abstract

A field experiment was conducted during rabi 2020–21 and 2021–22 at the Agricultural College Farm, Bheemarayanagudi, Karnataka, to evaluate different agronomic practices for enhancing mustard productivity. The experiment was laid out in a split–split plot design with three replications. The treatments consisted of four varieties (V₁: PM 25, V₂: PM 30, V₃: NRCPHBB-101 and V₄: Banarasi local), three seed rates (S₁: 5 kg ha⁻¹, S₂: 7.5 kg ha⁻¹ and S₃: 10 kg ha⁻¹) and two nutrient levels (F₁: 67.5:45:45 kg N:P₂O₅:K₂O ha⁻¹ and F₂: 90:60:60 kg N:P₂O₅:K₂O ha⁻¹). Pooled analysis of two years indicated that variety NRCPHBB-101 recorded significantly higher grain yield (986 kg ha⁻¹) compared to the other varieties. Among the seed rates, 5 kg ha⁻¹ proved superior in enhancing yield. Application of 90:60:60 kg N:P₂O₅:K₂O ha⁻¹ significantly improved grain yield compared to the lower nutrient level. The interaction effects revealed that NRCPHBB-101 sown at 5 kg ha⁻¹ seed rate and fertilized with 90:60:60 kg N:P₂O₅:K₂O ha⁻¹ recorded significantly higher grain yield (1044 kg ha⁻¹), net returns (Rs. 24,666 ha⁻¹) and benefit–cost ratio (3.47) compared to all other treatment combinations. The study concluded that adoption of high yielding variety NRCPHBB-101 with optimum seed rate and higher nutrient level is essential for maximizing productivity and profitability of mustard under rabi conditions in the region.
