Abstract
To achieve the goal of safe and sustainable food, the only realistic option now-a-days lies with the introduction of a low input farming system concept i.e. organic and integrated agriculture. Keeping in view the present scenario, a study was undertaken in Satyapole village, Haringhata block of Nadia district, West Bengal on integrated nutrient management in potatoes during rabi 2018 and 2019. The efficacy of different composts, in terms of their quality, easiness of preparation along with yield and economic attributes were accessed for the high nutrient loving crop, potato. The experiment was planned out in randomized block design (RBD) with 5 treatments and 4 replications. High yield with a marginal difference was found among all the treatments with integrated management. But, the treatment with 50% of recommended inorganic fertilizer dose (recommended dose N:P: K @ 200:150:150 kg/ha, 1/3 N, full P and 1/3 K as basal; 1st and 2nd top dressing with 1/3 N and 1/3 K) and vermicompost @ 5 ton/ha showed the best result. According to the B: C ratio composting with NOVCOM showed the best result whereas, in terms of the bio-degradation process with respect to its end-product quality, easiness of procedure, and cost, compost made through waste decomposer and NOVCOM has better results in comparison with vermicompost.
