The present experiment was carried out during the winter season of 2018-19 and 2019-20 at Regional Research Station (Coastal Saline Zone) under BCKV, Kakdwip, South 24-Parganas. The objective of the study was to find out the ideal combination of mustard genotype and fertilizer (NPK) levels for the coastal region of West Bengal. The field trial was set up in a split-plot design with four mustard genotypes (TBM 143, TBM 204, Kranti and Pusa Bold) in main plots and four fertilizer levels (Control, 100% RDF, 125% RDF and 150% RDF) in the sub-plots, each replicated thrice. Among the tested genotypes, Kranti and TBM 143 were found to be superior in terms of their growth attributes, yield components, seed yield (1.28 and 1.29 t ha-1, respectively), leaf chlorophyll content and nutrient content. Application of 150% RDF (120 kg of N, 60 kg of P2O5, and 60 kg of K2O ha-1) proved to be effective in producing the highest growth attributes, yield components, seed yield, leaf chlorophyll content and nutrient content, in all the tested genotypes. Nutrient-omission treatment (control plots) caused a serious reduction in growth attributes, yield components and seed yields (83% reduction as compared to 100% RDF) in all the mustard genotypes. In the coastal belt of West Bengal cultivation of both genotypes, Kranti and TBM 143 with 150% RDF are recommended for achieving higher yields.
