Abstract:
A field experiment was carried out to study the “Effect of integrated nutrient management on growth and yield of onion (Allium cepa L.) under Malwa Plateau of Madhya Pradesh” during Rabi seasons of 2020 and Rabi seasons of 2021 under irrigated conditions at Village–Ratadiya, Block – Ghattiya, Dist. – Ujjain Madhya Pradesh. The experiment consist has 12 treatments with control such as T₁-Control, T₂-100% inorganic RDF (N:P:K:S:Zn 120:60:80:40:05), T₃-Soil Test Based Fertilizer Recommendation (STV), T₄-75% RDF inorganic + 25% N through Vermicompost, T₅-75% RDF inorganic + 25% N through Poultry manure, T₆-75% RDF inorganic + 25% N through Neem cake, T₇-50% RDF inorganic + 50 N through Vermicompost, T₈-50% RDF inorganic + 50% N through Poultry manure, T₉-50% RDF inorganic + 50% N through Neem cake, T₁₀-100% N through vermicompost (VC) (7.0 t/ha), T₁₁-100% N through poultry manure (PM) (5.0 t/ha), T₁₂-100% N through Neem cake (NC) (3 t/ha) with three replications, three replications. The experiments has randomized block design with pooled data analysis. The observation to be recorded for plant growth parameters such as Plant height cm) at 45 DAT and at harvest and Length of leaf 45 DAT. Yield parameters like Length of bulb, Neck thickness and Diameter of bulb and Yield of bulb. The result revealed that the maximum Plant height (49.20 and 55.77 cm) at 45 DAT and at harvest and Length of leaf 45 DAT (49.85 cm). Yield parameters like, Length of bulb (8.53 cm), Neck thickness (2.44 cm) and Diameter of bulb (6.32 cm) and Yield of bulb 382.85q/ha, while the minimum was found under the treatments T₁ Control.
