Effects of Novel Slow Release Fertilizer on Banana Foliar Nutrients, Photosynthetic Rate, Chlorophyll Content, Yield and Fruit Quality
Abstract: Banana is global important cash crop; in recent years, soil-borne diseases and climate problems have caused its serious reduction in production especially in southern China. This paper described the application of a novel slow release fertilizer and its effects on banana growth and production. The paper studied banana foliar nutrients, photosynthetic rate, chlorophyll content, and yield performance. The results indicated that foliar content of macro-elements nitrogen, phosphate, potassium in Greenfeed® group was 12.5%, 10% and 34.8%, respectively, higher than the conventional compound fertilizers. Photosynthesis rate was found 10.5% - 32% higher and chlorophyll content was measured 9.5% - 10% higher than compound fertilizer treatment. Most importantly, the yield on weight of banana was concluded to be 14% - 20% higher than conven-tional treatment. Quality analysis on the harvested banana did not display much difference on the performance on total soluble solid, total sugar, and noticeably, soluble protein and edible per-centage were found higher in Greenfeed® treatment group. This novel slow release fertilizer is la-bor- saving and cost saving; its performances on banana quality were also found better than con-ventional fertilizer. This novel fertilizer is powered by zeolite, a component with beneficial effects on soil improvement, bringing up the Cations Exchange Capacity (CEC) and utility rate of fertilizers. This novel slow release fertilizer is worth to be further promoted in tropical and subtropical region in China.
