A study was conducted on French bean (Phaseolus vulgaris) at the coastal saline zone of West Bengal during winter 2017-18 and 2018-19. The soil texture was clay loam with pH 7.03. A location specific trial was done to standardize the combination dose for French bean towards productivity enhancement. The experiment was laid out in randomized bock design having 3 replications with 12 different treatments. The investigation was conducted with two strains of Rhizobium species -R (Rhizobium V1B/Bean-15 & Rhizobium V1B/F.bean-21) interacting on three applied levels of nitrogen-N (75%, 50%, 25% of the recommended dose @ 40kg/ha), and two levels of ammonium molybdate-Mo (50%, 100% of the recommended dose @30kg/ha) in variety “Arka Arjun” of French bean. The study generated information on the combined effects of biofertilizer and chemical fertilizer on several morphological attributes, protein content, nodulation and their final culmination on the yield. Studies on changing soil profile with respect to available nitrogen and population count of nitrogen fixers were also worked out to support the results. The mean sum of squares for all the traits were found statistically significant. The conclusive study suggests that the following treatment combinations viz. Rhizobium V1B/bean-15 +Nitrogen 50 % +Molybdenum 100 % and Rhizobium V1B/bean-15 +Nitrogen 25 % + Molybdenum 50 % applied to the French bean cv. Arka Arjun may be advised to the farmers of Coastal Saline Zone of West Bengal for productivity enhancement and maintaining soil sustainability.
