The study conducted at the Fruit research farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalrapatan, Jhalawar. The Integrated Nutrient Management (INM) effect on soil parameters of custard apple cv. Arka Sahan field. The experiment consisted of different treatment combinations comprising recommended dose of fertilizers, vermicompost and biofertilizer (Azotobacter, PSB and VAM). Experimental findings revealed that different treatments of integrated nutrient sources significantly improve the soil parameters. Among these integrated nutrient management treatments, treatment T10 comprising 50 % recommended dose of fertilizers + 50 % N through vermicompost and biofertilizers (Azotobacter 50 g + PSB 50 g + VAM 20 g ) was found significantly superior over other treatments with respect result in improving the water holding capacity (%), organic carbon percentage, N, P, and K content of soil under T10 treatment which was found significantly superior over other treatments. Like-wise, soil pH and electrical conductivity also reduced significantly under T10 treatment over other treatments.
