abstract
An experiment was carried out in the field of vegetable science experimental block at college of horticulture, Bagalkot, India during the year 2022-23 to study the influence of integrated nutrient management (INM) on growth, yield and quality of brinjal (Solanum melongena L.). Ten treatments of integrated nutrient management viz., T₁- 100% RDF [125(N) : 100(P₂O₅) : 50(K₂O)], T₂- 100% RDF + Azotobacter + AM + PSB, T₃- 75% RDN supplied through inorganic fertilizer + 25% RDN through FYM, T₄- 75% RDN supplied through inorganic fertilizer + 25% RDN through vermicompost, T₅- 75% RDN supplied through inorganic fertilizer + 25% RDN through FYM and vermicompost + azotobacter + AM + PSB, T₆- 50% RDN supplied through inorganic fertilizer + 50% RDN through FYM, T₇- 50% RDN supplied through inorganic fertilizer + 50% RDN through vermicompost, T₈- 50% RDN supplied through inorganic fertilizer + 50% RDN through FYM and vermicompost + azotobacter + AM + PSB, T₉- 75% RDN supplied through inorganic fertilizer + micro nutrients Fe, Mn, Cu & Zn, T₁₀- 50% RDN supplied through inorganic fertilizer + micro nutrients Fe, Mn, Cu & Zn were evaluated in Randomized Completely Block Design with three replications with plot sizes of 4.0 m × 3.6 m with the spacing of 120 cm X 60 cm. Significantly higher values of growth parameters like plant height, number of primary branches, stem girth and plant spread and yield attributes like fruit length, fruit diameter, fruit volume, average fruit weight, number of fruits per plant, fruit yield/plant, fruit yield/plot and fruit yield/ha were observed under treatment T₅ (75% RDN supplied through inorganic fertilizer + 25% RDN through FYM and vermicompost + azotobacter + AM + PSB). However, significantly minimum values of growth and yield attributes were observed under treatment T₁₀ (50% RDN supplied through inorganic fertilizer + micro nutrients Fe, Mn, Cu & Zn).
