Abstract:
The field experiment was directed at Agricultural Research Farm, Baruipur, South 24 – Parganas, West Bengal under University of Calcutta during the Rabi season of 2018–2019 & 2019-2020 to find out the “Effect of Integrated Nutrient Management on Growth, Productivity and Quality of Quality Protein Maize (QPM) (Zea mays L.) in Lower Gangetic Alluvial Zone of West Bengal”.The examination was spread out in a Randomized Block Design with three replications and twelve distinct treatments blends organic & inorganic sources of nutrients under well irrigated alluvial soil. VMH-53 (Vivek Maize Hybrid) was the selected cultivar with prolific high yielding characteristics and disease resistant capabilities. Two continuous rabi season trails uncover that mix of various natural and inorganic wellsprings of supplements expanded the growth, productivity and quality of QPM hybrid (Zea mays L.) without deteriorating the soil qualities. Treatment combination of (75% RDF @140:70:70 kg ha^-1) N:P:K + FYM 5 t ha^-1 + Azotobactor @7.5kg ha^-1 +PSB @7.5kg ha^-1) exhibited most efficient and economic than other treatment variables in terms of growth, quality, yield & yield ascribing characters net return and B: C proportion over other treatments. This was likewise liable for expanding the supplement status of the soil in respect of organic carbon, available N, P, K respectively over introductory status of the soil. These result suggest that in maize organic composts like FYM, Vermicompost, Azotobactor + PSB, could be effectively used in combination with chemical fertilizers to benefit the crop and improve soil health and soil fertility status there by increasing productivity, quality ensuring nutrition and food security.
