摘　　要：A field study was conducted to investigate the effect of Aquasap, a commercially manufactured biostimulant from seaweed Kappapphycus alvarezii on some hills and foothills banana varieties namely Robusta （AAA）, Njali poovan （AB）, Red banana （AAA） and Nendran （AAB） by applying at 5% through foliar spray at the 3rd, 5th and 7th month of plantation. Both quantitative and quality data of fruits were analyzed along with vegetative growth of the plants. The seaweed biostimulant was found very effective on increasing the weight and nutritional contents of all four banana varieties tested. The highest yield was found in Robusta with 56.58% over control followed by Njali poovan, Red banana and Nendran with 19.08%, 39.35% and 11.46%, respectively. Yield of fruits per hectare of four varieties treated were 76.96, 19.23, 29.68 and 23.37 metric ton （mt）, respectively. Fruits of treated plants also showed less moisture level as compared to control with 240.61%, 62.30%, 61.68% and 37.18% more carbohydrate, 283.71%, 94.07%, 62.87% and 38.93% higher proteins and 153.02%, 47.37%, 58.73% and 31.48% higher minerals respectively as compare to control plants. Therefore, the simple practice of application of eco-friendly seaweed based biostimulant would benefit small and marginal farmers of banana.
