Leaf nutrient concentrations of different clones of rubber (Hevea brasiliensis) were compared under two separate studies to find out variations among the clones. In the first study, comparisons were made for two years from the leaf analytical values of different clones from two field experiments. In one experiment significant variation was observed for N, P, K, Ca and Mg during the fifth year from planting. During the seventh year from planting, micronutrients Fe, Mn and Zn were also compared and variation was observed only for N and Fe. In the other experiment, significant variation for N, P, K, Ca and Mg were observed for both the years. Among the micronutrients significant difference was observed for Fe. In a separate study leaf nutrient values for N, P, K, Ca and Mg of five popular clones from a large data base were compared and significant difference was observed among the clones.
