An experiment was conducted at Horticultural Research Station, Mondouri, BCKV, WB during pre-kharif season of two consecutive years (2019-2020 and 2020-2021) to observe the role of organic amendments on yield and quality of mint (Mentha arvensis L.) under New Alluvial Zone of West Bengal. Twelve treatments viz. T₁-100% farmyard manure (30 t ha^-1), T₂-100% vermicompost (15 t ha^-1), T₃-100% poultry manure (7.5 t ha^-1), T4-100% neem cake (2.5 t ha^-1), T5-50% FYM+ 50% VC, T6-50% FYM + 50% PM, T7-50% VC+50% PM, T₈-25% FYM+25% VC +25% PM + 25% NC, T9-50% FYM+ 50% NC, T10-50% VC+ 50% NC, T11- 50% PM+ 50% NC and T₁₂-Control (150:60:60 NPK kg ha^-1) were evaluated in RBD with three replicates. The mean maximum plant height (23.98 cm), number of primary branches plant^-1 (5.52), secondary branches plant^-1 (16.84), leaf length (3.14 cm), leaf width (1.95 cm), spread in North-South (29.33 cm), East-West (29.49 cm), fresh herbage yield (3.38 kg plot^-1), projected fresh herbage yield (125.06 q ha^-1), essential oil content (1.61 ml 100 g^-1 dry leaves), net profit (Rs. 224077 ha^-1) and B:C ratio (2.53:1) were obtained under T8 (25% of FYM + 25% of VC +25% of PM + 25% of NC ) which proved to be the best performing treatment combination with respect to higher production, profit and reduction in environmental hazards due to use of chemical fertilizers.
