A study aimed at evaluating the economics of cultivation of Kinnow mandarin (Citrus nobilis x Citrus deliciosa) using different integrated nutrient management treatments. Three organic manures (FYM, poultry manure and vermicompost) under three different experiments were used along with inorganic fertilizers and Azotobacter. Total cost of cultivation was maximum ( 98905.00) with the application of cent per cent application of nitrogen as vermicompost augmented with Azotobacter. The net returns on investment were highest ( 186968.00) under treatment where plants were applied with 25 per cent nitrogen as vermicompost and 75 per cent nitrogen as urea augmented with Azotobacter. Maximum benefit cost ratio of (1:3.28) was obtained under treatment comprising 50 per cent nitrogen as poultry manure and 50 per cent nitrogen as urea augmented with Azotobacter. A comparison between the three integrated nutrient management experiments in Kinnow mandarin revealed that maximum returns on investments can be achieved when half of the recommended dose of nitrogen through inorganic fertilizers is replaced with organic source (vermicompost) along with the application of biofertilizer.
