[Objective] To study the major element demand of Moringa oleifera.[Method] The effects of formulated fertilization of N, P and K on the growth, leaf pigment content and leaf water content of Moringa oleifera young individuals were tested in Yuanyang dry-hot valley by using fertilizer experiment design "3414".[Result] The results showed that fertilization significantly promoted the growth of M. oleifera young trees. Fertilizer N significantly affected all indexes; Fertilizer P significantly affected all indexes except the ground diameter and leaf water content; Fertilizer K significantly affected the crown height, percentage of crown height, and leaf water content. Comprehensive results of variance analysis, range analysis, multiple comparison and correlation analysis showed that medium to high amount of fertilizer could significantly promote the growth of height, ground diameter, crown diameter, and accumulation of leaf pigments.[Conclusion] Among those treatments, N3P2K3 is the superiorly effective. The results also suggested that M. oleifera trees need a great amount of NPK fertilizer to maintain rapid growth in young stage.
