Effect of Controlled Release Fertilizer on the Yield and Quality of Banana and Nutrient Use Efficiency

A field experiment was conducted to study the effect of controlled release fertilizer CRF on banana in Zhangzhou of Fujian province.The results showed that the yield of banana after application of CRF was increased by 6.18%(2 204.7 kg·hm-2) and the total soluble solids and edible part ratio were also increased compared with the normal NPK fertilizers at medium soil fertility.Meanwhile,the uptakes of N,P and K were 277.44,33.43 and 974.51 kg·hm-2,respectively,and the utilization efficiency of N,P and K were 15.1%,17.4% and 34.7%.Our results suggest that,compared with the normal N,P and K fertilizers,the use efficiency of CRF were increased by 42.7%,1.2% and 10.4%,respectively.
