Abstract:
Present experiment entitled “Effect of Integrated Nutrient Management on growth & yield of rabi maize (Zea mays L.)” was conducted during the Rabi season of 202223 at Agriculture Research Farm, Rama university, Mandhana, Kanpur. The experiment was laid out in Randomized Block Design (RBD) with three replications and 10 treatments viz. T₁ = Control T₂ = 100% NPK (180:60:40), T₃ = Seed treatment with Azotobacter @200 g/10 Kg seeds T₄ = Seed treatment with Azospirillum @200 g/10 Kg seeds T₅ = Seed treatment with Azospirillum + Azotobacter, T₆ = 50% NPK + Seed treatment with Azotobacter, T₇ = 50% NPK + Seed treatment with Azospirillum, T₈ = 50% NPK+ Seed treatment with Azospirillum + Azotobacter and T₉ = 75% NPK+ seed treatment with Azospirillum + Azotobacter and T₁₀ = 100% NPK+seed treatment with Azospirillum + Azotobacter. The result of the study revealed that the maximum plant height (225.08) cm, dry matter (467.00 gm), Leaf area Index (0.17), Cob Length (17.33), Number of cobs per plant (17.33), number of cob per plant (2.09), number of grain per cobs (15.56) yield per hectare (141.59 q) and C:B ratio (2.11) was reported in treatment T₁₀ = 100% NPK+seed treatment with Azospirillum + Azotobacter followed by treatment T9 = 75% NPK+ seed treatment with Azospirillum + Azotobacter Basis on these results treatment T₁₀ can be suggested to the local farmer of Kanpur regions to obtain 15 higher yield and net return in rabi maize.
