Response of growth, yield and postharvest qualities of Taiwan banana to Tai-Fei compound fertilizers.

The effects of Tai-Fei compound fertilizers on the growth, yield and postharvest quality of GCTCV-217 (Cavendish, AAA), a Fusarium wilt-resistant banana clone, were investigated. Application of Tai-Fei compound fertilizer No. 4 with 22% K resulted in earlier fruit production; however, the same was true in ratoon crops with Tai-Fei compound fertilizers No. 1 and 5, which have a higher N but a lower K content than the Tai-Fei compound fertilizer No. 4. The use of various compound fertilizers did not make a significant difference to the N content of banana leaves, but a significantly higher K content was found in either the treatment of single Tai-Fei compound fertilizer No. 4 or the treatments of double compound fertilizers including Tai-Fei compound fertilizer No. 4. Fertilizer management of banana plantations using Tai-Fei compound fertilizers No. 1 or 5 had the following physiologically adverse effects: a faster yellowing and curling of older leaves (K deficiency symptom), inferior vegetative g

rowth and yield potential, a higher frequency of uneven degreening in banana peel, a lower banana mass, and a shorter shelf life of ripened bananas. Thereafter, in a general banana plantation, it is advisory to place an emphasis on the application of compound fertilizers with a higher grade of potassium for the fertilization management, and Tai-Fei compound fertilizer No. 4 is of a preferable option, the annual rate no more than 1.5 Kg per plant is recommended. Alternatively, an acceptable yield and fruit quality could also be obtained if banana plants are first fertilized with Tai-Fei compound fertilizer No. 1 or 5, and then switched to Tai-Fei compound fertilizer No. 4 during the stage of floral bud differentiation. For soils low in potassium, a suitable amount of potassium chloride based upon soil and leaf analysis should be applied as a dresser fertilizer.
