A field experiment was conducted to evaluate the effect of Integrated Nutrient Management on growth, biomass yield and nutrient uptake by buckwheat and nitrogen, phosphorus and potassium status of soil after harvest of crop. The experiment having fifteen treatments including recommended dose of nitrogen, phosphorus and potassium alone and various combinations of  Farm Yard Manure, Azotobacter and Phosphorus  Solubilising Microorganisms with rest of recommended dose of nitrogen, phosphorus and potassium was conducted in Randomised Block Design at Crop Research Center of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar.  Growth parameters, i.e., plant height and numbers of branches were not influenced by various INM  treatments, however, biomass yield and nitrogen uptake were significantly superior over control. Organic carbon and available phosphorus and potassium status were not affected by various INM treatments.
