Abstract:
The present investigations entitled “Effect of integrated nutrient management and foliar spray of humic acid on growth, yield and quality of brinjal” was undertaken at Instructional Farm, Department of Vegetable Science, Dr. PDKV, Akola during Rabi season of 2021-2022. The experiment was laid out in Randomized Block Design with 10 treatments and 3 replications. The Treatments includes: T₁- 100% RDF, T₂- 100% RDF+ FYM @ 5 t ha^-1, T₃- 100% RDF+ NPS compost @ 2.5 t ha^-1, T₄, T₅ and T₆- 100% RDF+ FYM @ 5 t ha^-1+ 4 sprays of humic acid @ 0.5, 1 and 1.5% respectively, T₇, T₈ and T₉- 100% RDF+ NPS compost @ 2.5 t ha^-1+ 4 sprays of humic acid @0.5,1 and 1.5% respectively, T₁₀- Absolute control. Among all treatments T₈ (100% RDF+ NPS compost @ 2.5 t ha^-1+ 4 sprays of humic acid @1%) treatment was recorded significantly maximum plant height (80.03 cm), Number of branches (11.2), plant spread (57.06 cm), leaf area (186.8 cm²), stem girth (3.07 cm) at 90 DAT, chlorophyll index (37.90) at 60 DAT and yield parameters viz. fruits plant^-1 (52.82), fruit girth (3.18 cm), fruit length (11.46 cm), average fruit weight (31.30 g), fruit yield per plant (1.65 kg), fruit yield per plot (33.07 kg) and fruit yield (408.38 q ha^-1).
