The effect of different methods of latex extraction (T) and stimulation (S) on the status of nutrient present in the latex, bark and leaf of clone RRIM 901, Panel BO-1 was studied to establish a relationship between the status of nutrient in tissue and tree productivity. The results showed no consistent pattern on the influence of the interaction effect of T X S on the drainage of elements from the latex and removal of nutrient from the bark. The influence of T X S interaction on N and Mg was observed both in the latex and the bark, while for P and K, the influence was confined solely in the latex or the bark. The study indicated that nutritional stress possibly caused the declining yield response as obtained from gaseous stimulation on young Hevea trees of clone RRIM 901, Panel BO-1. Therefore, to achieve sustainable crop production, it is essential to have a balanced situation between the amount of crop harvested and the ability of the tree to replenish, not only the crop harvested but also the amount of elements lost in the latex and bark after completion of tapping.
