Online published on 15 December, 2016. Abstract Potato (Solanum tuberosum L.) has emerged as one of the most important food crops in India. It is highly input efficient and responsive crop. Nutrient management hasplayed an important role in achieving self-sufficiency in food grain production. Integrated use of biofertilizers, organic manures in combination with the chemical fertilizers and their proper management for better growth and productivity is very essential. Keeping these facts in perspective, this field experiment was conducted during rabi season of 201314 at the farmer's field in Bahadurpur, Birbhum, the sub-humid sub-tropical lateritic belt of West Bengal to study the yield variation in potato at different fertility level. The results showed that the crop receiving 80% RDN(N: P: K=200: 150: 150 kg/ha) through chemical fertilizer+20% RDN through vermicompost recorded greater plant height, dry matter accumulation, crop growth rate tuber growth rate and tuber bulking rate at different growth stages than 100% RDN through chemical fertilizer and this treatment ultimately produced the highest tuber yield. Biofertilizer exerted significant effect on growth attributes like dry matter accumulation, tuber bulking rate and tuber yield of potato.
