Abstract
The op timum N and K2O application rate and the effects on banana quality were studied by ield experiments in Zhangzhou banana gardens. The results showed that there were significant effect on increasing yield after applicating a suitable amount of N fertilizer in high yield or middle-lower yield banana gardens. But in middle-lower yield banana gardens, significant increased yield was achieved after K fertilizer application combined middle or high amount of N fertilizer. It was beneficial to improving the banana agronomic traits, quality such as fruit solids, soluble sugar and vitamin C content applying N and K fertilizers in suitable amount and the proportion. In high yield banana gardens, economic application rate was N 691 kg/hm2 and K2O 1 154 kg/hm2, and the proportion of N and K2O was 1∶1.67.But, in the middle-lower yield banana gardens, the optimum amount was N 631 kg/hm2 and K2O 877 kg/hm2, and the proportion was 1∶1.39. The results indicated that the potash demand rate in high yield banana gardens was significantly higher than that of the middle-lower yield banana gardens.
