Abstract: The fertilization experiment with introduced Carica papaya was carried out in Xinping County, Yunnan Province, and some growth indexes such as crown diameter, crown depth, leaf quantity, inflorescence and fruit yield were investigated. It was showed by the results that among the different treatments of fertilization, 100 g and 150 g of fertilizer per plant were the better treatments for the increments of crown diameter and the leaf quantity. There was less effect of fertilization on the increase of crown depth. The better effect on the amount of flowers and fruits was got with 150 g of fertilizer per plant.
