The effect of organic and inorganic fertilizers supplemented with bio-fertilizers on growth parameters of custard apple cv. Arka Sahan during growth period (September 2010 to March 2011) were studied. The experiment consisted of different treatment combinations comprising recommended dose of fertilizers, vermicompost and bio-fertilizer (Azotobacter, PSB and VAM). Experimental findings revealed that different treatments of integrated nutrient sources significantly increased the plant parameters. Among these integrated nutrient management treatments, treatment T10 comprising 50% recommended dose of fertilizers + 50% N through vermicompost and bio fertilizers (Azotobacter 50 g + PSB 50 g + VAM 20 g) was found significantly superior over other treatments including control with respect to growth parameters such as per cent increase in plant height, rootstock girth, scion girth, plant spread, and number of primary branches per plant etc. in custard apple cv. Arka Sahan.
