Abstract

A field experiment was carried out at Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal during kharif season of 2019 and 2020, following three times replicated split plot design with 3 soybean varieties (V1: PS 1225; V2: YEZIN 15; V3: PS 24) in main plot and 5 nutrient management options (N1: 100% recommended dose of fertilizer (RDF) i.e. N: P2O5: K2O-20:60:40 kg/ha; N2: 75% RDF + 3 t/ha farm yard manure (FYM); N3: 75% RDF+ 1.5 t/ha vermicompost; N4: 75% RDF + 3 t/ha FYM + 25 kg/ha ZnSO4; N5: 75% RDF + 1.5 t/ha vermicompost + 25 kg/ha ZnSO4) in subplot. Results revealed that soybean variety PS 24 grown under application of 75% RDF + 1.5 t/ha vermicompost + 25 kg/ha ZnSO4 recorded highest plant height (73.81 cm at harvest), leaf area index (5.39 at 90 days after sowing i.e. DAS), number of branches/plant (11.40), dry matter accumulation (767.09 g/m2) and crop growth rate (14.02 g/m2/day). Application of 75% RDF+ 1.5 t/ha vermicompost also ensured high growth attributes soybean varieties specially in PS 24. Conversely, Myanmar variety YEZIN 24 grown under 100% RDF did not perform well due to its non-adaptability in West Bengal condition.
