Potentiality of three organic manure namely vermicompost, farmyard manure (FYM) and poultry manure (PM) vis-à-vis, 0 per cent to100 per cent recommended dose of fertilizer-NPK in French bean (Variety: Arka Anoop). Field experiment was conducted in cluster form at Sihphir venghlun village, Aizawl district in Mizoram, NEH Region, India during the year 2015-16. Among the various treatments 75 per cent RDF along with 25 per cent RDF met from vermicompost along with bio-fertilizer (T 2) application produced better result in terms of germination per cent (85.34 %), number of pod per plant (20 number), pod yield per plant (300.05 g) and pod yield (14.00 t/ha). And was found to give more remunerative and advantageous in respect of maximum net return (Rs. 254000.00) and cost: benefit ratio (2.64) when compared to other treatments.
