An experiment was conducted to find out the effect of organic and inorganic sources of fertilizers along with bioinoculants on growth, yield and quality of aonla cv. NA-7 during 2016 and 2017. Maximum increment in vegetative parameters viz., increment in plant height (10.92%), plant spread (13.91% NS and 13.88% EW) and canopy volume (40.32%) was recorded with the application of cent per cent nitrogen through urea and Azotobacter with recommended dosage of SSP and MOP. Yield parameters viz., fruit length (4.52 cm), fruit diameter (5.24 cm), fruit weight (48.56 g), fruit volume (47.80 cc), pulp weight (40.49 g) number of fruits per tree (2389.57) were recorded maximum when 25 per cent of nitrogen was applied as FYM and 75 per cent was applied as urea along with Azotobacter application. Maximum yield per tree (116.05) was also recorded under the same treatment combination. All the fruit quality parameters improved with the integrated application of FYM along with inorganic fertilizers and biofertilizers. The total soluble solids (11.26 0Brix), total sugars (6.72 per cent) and reducing sugars (3.42 per cent) were found maximum in fruits receiving 50 per cent nitrogen in the form of FYM and 50 percent through urea augmented with Azotobacter, whereas the ascorbic acid content was found maximum (625.23 mg/100g of pulp) with cent per cent nitrogen through application of FYM augmented with Azotobacter. The results suggested that 25 per cent nitrogen can be replaced through chemical fertilization along with FYM on N-equivalent basis plus Azotobacter inoculation.
