Résumé : Fertilization is one of the most important factors that affect growth and yield of rubber tree. It takes a high rate of capital investment for plantation. Regulation on fertilizer quantity or/and ratio among fertilizer nutrients results in remarkable economical and technical impacts on the rubber plantation during the immature period. During the mature period, data are still controversial. This experimental study aimed to evaluate the effects of fertilizer on the rubber growth in immature stage. After seven years of experimentation, results showed that fertilization had a positive effect on the cumulative girth increment (cm) by 6% whereas the tapped rubber trees at opening increased by 7 to 13%.
