Abstract


An experiment was carried out at the Regional Research Sub-Station Sekhampur of Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India for two consecutive years during 2008-09 to 2009-10 on to study the effect of integrated nutrient management on growth and yield of aonla cv. NA-7. Observations on plant morphological characters and yield attributes were recorded at maturity of 3 years old aonla trees. The highest plant height (323.00cm) was recorded in trees supplied with 100: 25:150 g NPK + 10kg FYM+ 50g PSB plant-1. The highest number of branches was noted in 100:25:150 G NPK + 10KG FYM + 50G PSB plant-1 treatment (15.30) and the lowest number of branches could be noted against the 100:50:150 g NPK plant-1 treatment (9.53) consisting of exclusive application of inorganic fertilizers. The highest number of fruits was observed in 100:25:150 g NPK + 5kg vermicompost + 50g PSB plant-1 (73.17) which was closely followed by 100:25:150 g NPK + 10kg FYM + 50g PSB plant-1 treatment (72.73). The highest yield was recorded in 100:25:150 G NPK + 10KG FYM + 50G PSB plant-1 (1781.43 g plant-1) whereas lowest fruit yield was recorded in 100:50:150 g NPK plant-1 (831.96 g/plant). In general, the treatment comprising of integration of inorganics, organics and bio-fertilizers produced 50.92% more yield than the application of inorganic fertilizers only (100:50:150 g NPK plant-1treatment). It appears from the investigation that application of 100: 25:150 g NPK plant-1+ 10kg FYM+ 50g PSB plant-1and 100:25:150 g NPK + 10kg FYM + 50g PSB plant-1) treatments are beneficial for increasing vegetative growth as well as improving yield and yield attributing characters of aonla cv. NA-7 under red and lateritic region of West Bengal
