Enhancing Fruit Yield in 'Ney Poovan' Banana (Musa paradisiaca L.) by De-Navelling and Feeding N, K and S through Distal Stalk-End of the Bunch
De-navelling and feeding ammonium sulphate (AS) (5-25 g/plant) with or without potassium sulphate (2.5-12.5 g/ plant) blended in 500 g of fresh cow-dung and applied to the distal stalk-end of the bunch of 'Ney Poovan' banana (Musa sp. L., AB) showed that the nutrients moved from the blend...

| Sumario: | De-navelling and feeding ammonium sulphate (AS) (5-25 g/plant) with or without potassium sulphate (2.5-12.5 g/ plant) blended in 500 g of fresh cow-dung and applied to the distal stalk-end of the bunch of 'Ney Poovan' banana (Musa sp. L., AB) showed that the nutrients moved from the blend into the bunch and significantly enhanced weight of the fruits and of the bunch, compared to retention of flower, de-navelling (removal of male inflorescence) and application of 500 g cow-dung only to the excised distal stalk- end of the bunch. De-navelling caused 7.1% (5623 g) higher bunch yield, which increased to 13.9% (5980 g) when cow dung alone was applied after de-navelling. When cow dung was blended with 5 g of AS and 2.5 g of Sulphate of Potash, the response was 66.5% (9362 g) over de-navelling and application of cow dung alone and 78.3% (9362 g) over retention of male bud throughout (5250 g). A significantly higher N content, N uptake, Ndff (nitrogen derived from fertilizer), fertilizer N uptake, utilization of fertilizer and K and S content were observed when cow-dung enriched with AS and SOP was applied. Nitrogen content and all the parameters of N use were distinctly higher in the basal portion of the bunch indicating the flow of the applied nutrients upward from the de-navelled end. Results showed that application of 5 g ammonium sulphate and 2.5 g sulphate of potash blended in 500 g of fresh cow dung to the distal stalk-end of the bunch of 'Ney Poovan' banana was the most promising in boosting the yield, improving the nutritional composition in respect of N, K and S without adversely affecting the fruit quality. |
