Effect of Integrated Nutrient Management on Biometric Parameters, Yield Parameters and Economics of Baby Corn (Zea mays L.)

A field experiment was conducted during the kharif season of 2009 at the Agricultural farm of Palli Siksha Bhavana (Institute of Agriculture), Visva–Bharati, Sriniketan, Birbhum, West Bengal. The soil at experimental site was analyzed to be low in available N, medium in available P₂O₅ and medium in available K₂O. The soil texture was sandy loam in texture and it was slightly acidic (pH 5.8) in reaction. The experiment consisting of 8 treatments such as T₁=100% RD, T₂=75% RD, T₃=50% RD, T₄=75% RD + 25% N (FYM), T₅=50% RD + 50% N (FYM), T₆=100% RD + Azotobacter, T₇=75% RD + 25% N (FYM) + Azotobacter and T₈=50% RD + 50% N (FYM) + Azotobacter were laid out in Randomized Block Design with three replications. Observations on biometric parameters like leaf area, chlorophyll-a, chlorophyll-b and total chlorophyll; yield parameters like average length of cobs, average girth of cobs, % barrenness, number of baby corn per ha and yield of total husked baby corn were recorded and analyzed statistically.
