A field experiment entitled “Effect of integrated nutrient management on growth and yield of Okra” was conducted at Research cum Instructional farm of College of Horticulture and Research Station Saja, Bemetara (C.G.) during Zaid season of 2024-25. The experiment was laid out in Randomized Block Design with three replications. The treatments consisted of eight nutrient management practices viz., (T₀) Control, (T₁) 100% RDF (100:50:50 kg NPK/ha), (T₂) 70% RDF + 30% Azospirillum, (T₃) 50% RDF + 50% FYM, (T₄) 50% RDF + 50% Vermicompost, (T₅) 40% RDF + 30% Azospirillum + 30% FYM, (T₆) 40% RDF + 30% Azospirillum + 30% Vermicompost and (T₇) 40% RDF + 30% FYM + 30% Vermicompost. Observations on growth parameters viz., plant height, number of branches, number of leaves, leaf area, intermodal length and yield parameters viz., number of flowers, number of fruits, fruit length, fruit diameter and fruit yield of okra crop were recorded at harvest and statistically analyzed were also worked out. The study revealed that integrated nutrient management significantly influenced the vegetative growth of okra. The highest plant height, number of leaves, leaf area, number of branches and internodal length were recorded under (T₁) 100% RDF (100:50:50 kg NPK/ha), which was statistically comparable to (T₂) 70% RDF + 30% Azospirillum. Treatments (T₄) 50% RDF + 50% Vermicompost and (T₃) 50% RDF + 50% FYM showed moderate improvements over the control (T₀). Similarly, reproductive growth and yield traits were maximized under (T₁) 100% RDF (100:50:50 kg NPK/ha) with the highest number of flowers, fruits per plant, fruit length, fruit diameter and fruit yield (320.54 g per plant), followed closely by (T₂) 70% RDF + 30% Azospirillum. Which was statistically significant superior with treatments (T₄) 50% RDF + 50% Vermicompost and (T₃) 50% RDF + 50% FYM, while the lowest yield was observed in the control (T₀).
