A Field experiment was carried out during the rabi seasons of 2021-22 and 2022-23 at the Krishi Vigyan Kendra Balrampur of Indira Gandhi Krish Vishwavidyalaya, Raipur (C.G) to evaluate the effect of INM on yield and yield parameters of cauliflower in relation to different organic and inorganic fertilizer levels in inceptisol of Northern Hills Zone of Chhattisgarh. The experiment was laid down in Randomized Block Design (RBD) with eight treatments which replicated three. The treatments in the T₁ (Control), T₂ RDF (180:120: 100, N:P₂0₅:K₂0), T₃ (75% RDF), T₄ (50% RDF), T₅ (75% RDF + 2.5 t/ha vermicompost), T₆(75% RDF + 5 t/ha FYM), T₇ (50% RDF + 5 t/ha vermicompost) and T₈ (50% RDF + 10 t/ha FYM).

The application of recommended dose of fertilizer along with FYM or vermicompost found significantly superior to produced maximum growth and yield of cauliflower. The results on plant height of cauliflower measured at 20, 40 and 60 days after transplanting, indicated that the positive impact of integrated nutrient management. The highest plant height by application of recommended doses of NPK through RDF or integrated use of organic and inorganic fertilizer ie. (75% of the RDF along with vermicompost) or (75% RDF + 5 t/ha FYM) or (50% RDF + 10 t/ha FYM). The highest curd length was observed in integrated treatments (75% RDF + 2.5 t/ha Vermicompost) (12.65 cm) followed by (75% RDF + 5 t/ha FYM) (11.42 cm). The highest curd breadth was observed in the treatments, (75% RDF + 2.5 t/ha Vermicompost) (14.90 cm), (75% RDF + 5 t/ha FYM) (14.62 cm), (50% RDF + 5 t/ha Vermicompost) (13.42 cm) and (50% RDF + 10 t/ha FYM) (13.27) showed at par curd breath with RDF (180:120:100, N: P₂O₅:K₂O) (15.40 cm). the pooled data for curd yield revealed that treatment (75% RDF + 2.5 t/ha Vermicompost) (270.84 qt/ha) , (75% RDF + 5 t/ha FYM) (268.65 qt/ha), (50% RDF + 5 t/ha Vermicompost) (263.11 qt/ha) and (50% RDF + 10 t/ha FYM) (259.24 qt/ha) which were statistically at par with each other and also with RDF (180:120:100, N:P₂O₅:K₂O) (278.42 qt/ha). The lowest yield was observed in control (125.05 qt/ha).
