A field experiment was carried out at Research farm, Department of Horticulture, School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema campus, Nagaland during 2018-2019 to evaluate the effect of integrated nutrient management on growth, yield, quality and economics of French bean (Phaseolus vulgaris L) under foothill condition of Nagaland. The experiment was laid out in randomized block design with eleven treatments and three replications. Results revealed that the application of different levels of fertilizes, organic manures and biofertilizers either alone or in combination significantly increased the growth, yield and quality of French bean as compared to control. Application of 50% NPK as inorganics + 50% vermicompost exhibited maximum plant height (34.3 cm), branches plant-1 (9.4), leaves plant-1 (27.3), pods plant-1 (26.3), length of pod (14.9 cm), width of pod (1.04 cm), seeds pod-1 (7.1), fresh weight of pod (7.1 g), pod yield (246.99 q ha-1) and crude protein content (28.8%). There was a significant build up of organic carbon and available nutrients except available nitrogen in post harvest soil with INM practices and maximum values of organic carbon (16.8g kg-1), available P (26.8 kg ha-1) and available K (126.8 kg ha-1) were recorded with 50% NPK as inorganics + 50% vermicompost. While maximum value of available nitrogen (297.6 kg ha-1) in post harvest soil was recorded with 100% NPK as inorganics. The highest net return of Rs 3, 45,388 ha-1along with cost benefit ratio of 3.04 was recorded in the treatment having50% NPK as inorganics + 50% FYM.
