An experiment was conducted during the rabi season of the years 2015–16 and 2016–17 at the Instructional Farm of Uttar Banga Krishi Vishwa Vidyalaya, Pundibari, Cooch Behar to study the performance of eight bush type frnch bean (Phaseolus vulgaris L.) varieties (Shagun, Victoria, Falguni, Falkon Improved, Arka Komal, special Jhati Beans, Nandini and Basuki) regarding growth, fresh pod yieldand quality in thisregion with andwithout Rhizobium inoculation. The experiment was laid out in factorial randomized block design with three replications. In case of inoculation treatment, irrespective of varietal differences, seeds were treated with Rhizobium phaseoli10g/kg of seed. Common fertilizer dose of 80: 40: 40 N: P₂O₅: K₂Okg/ha was applied in each plot. The experimental results revealed that Rhizobium inoculation increased the yield and quality parameters viz, protein %, vitamin-A content and ascorbic acid content in the fresh pods of the frenchbean varieties. However, flowering and harvesting were recorded earlier in without Rhizobium inoculation treatment due to less accumulation of nitrogen content inside the plant bodies. Under Rhizobium inoculation Special Jhati Beans recorded the highest pod yield (23.05 tonnes/ha) followed by Victoria (22.43 tonnes/ha) and Arka Komal (21.95 tonnes/ha). Regarding without inoculation treatment Arka Komal recorded the higher yield (20.05 tonnes/ha) followed by Special Jhhati Beans (20.01tonnes/ha) and Nandini (18.76 tonnes/ha). Considering the benefit: cost ratio, french bean varieties ‘Special Jhhati Beans’ and ‘Victoria’ might be selected for the terai region of West Bengal with a benefit: cost ratio of 2.94 and 2.83 respectively.
