[Objective] To study the effect of different formula fertilization on the growth and yield component of Moringa oleifera. [Methods] Orthogonal design L9 (34) with 3 factors 3 levels fertilization experiment was carried out. [Results] The results showed that fertilization treatment significantly promoted the growth in each period, and N fertilizer and K fertilizer dominated role in the vegetative growth. The optimal combination suitable for the growth of plant height and ground diameter was N150P40K100, while that for the crown and the number of branch growth was N85P85K100. The reproductive growth increased obviously compared to control. Low concentration of nitrogen and high concentration of phosphate and potash fertilizer contributed to M. oleifera flowering and fruit setting, and improved the pod and seed yields, and significantly increased the ordinal numbers, the numbers of mature fruit, hundred kernel weight and fruit-set rate. [Conclusion] Reasonable proportion of formula fertilization could significantly promote growth and increase production of M. oleifera. The optimal combination is N40P150K100 regarding the pod and seed yields.
