บทคัดย่อ (EN): Hevea brasiliensis is a tree crop with a life span of more than thirty years. A study was conducted at the Rubber Research Institute of India for two years to measure nutrient content and nutrient drainage from some of the promising Hevea clones through latex. Thirteen clones of 13 year old were selected for the study. Latex samples of middle 5 trees in each clone under normal tapping were pooled together to form a composite sample and replicated 4 times. Latex samples were collected on bimonthly basis for two years and analyzed for N, P, K, Mg, Fe, Mn, Cu and Zn. Also collected monthly yield and calculated the actual drainage of nutrients from different clones through latex. Significant clonal difference in latex nutrient content was observed for N, P, K and Mg. Among the micronutrients significant difference was observed only for Zn and Cu. The clonal differences in nutrient removal through latex were significant through the analysis of variance test. The removal of N, P, K and Mg from different clones through latex vary from 6.37 to 19.14; 2.72 to 8.65; 6.30 to 18.82 kg and 2.57 to 7.69 kgs per hectare per year respectively. Similarly removal of Fe, Mn, Zn and Cu from different clones vary from 39.00 to 88.02 g; 1.20 to 2.39 g; 5.72 to 20.11 g and 5.63 to 18.50 g per hectare per year respectively. It was also noted that the actual removal of N, P, K and Mg from high yielding clones is well above the values reported earlier. Also the micronutrients in latex and its removal through latex exhibited more clone variation than macronutrients. Hence the depletion of soil nutrient reserves and consequent fertilizer requirements can vary considerably depending on the clones.
