The analysis was carried out by using a Randomized Block Design (RBD) with 3 replications and 7 treatments, namely, T₁ [Farmers' Fertilizer Practice (120:60:40 kg N:P₂O₅:K₂O ha^-1)], T₂ [Recommended Dose of Fertilizer (RDF) (150:60:40 kg N:P₂O₅:K₂O ha^-1)], T₃ [RDF + Green Manuring (Dhaincha)], T₄ (RDF + 5 t ha^-1 FYM), T₅ (RDF + 10 t ha^-1 FYM), T₆ (RDF + 15 t ha^-1 FYM), and T₇ (RDF + 20 t ha^-1 FYM). Other cultivation practices were kept according to standard recommendations.

Plant height (cm), leaf area index (LAI), dry matter accumulation, and crop growth rate (g.m^-2.day^-1) were all recorded under the T₇ treatment, which was statistically at par with T₆ at all stages of crop growth. The T₇ treatment had a 50.4% higher average cob yield without husk than the T₁ treatment (Farmers' Fertilizer Practice) as well as the highest gross return (Rs. 3,78,938.52 ha^-1) and net return (Rs. 2,77,588.52 ha^-1),but the T₆ treatment had the highest benefit-cost ratio (4.02).

As a result, from the findings it can be concluded that cultivating baby corn in the new alluvial zone of West Bengal with RDF + 15 t ha^-1 FYM is a suitable option for increasing yield, income and nutrients absorption during the rabi season.
