The optimun rates of fertilizers were 1.1kg sulphate of ammonia, 0 to 0.83kg sphos phosphate and 1.8kg muriate of potash/palm/yr giving an yield of 12kg copra/palm/yr. aNPK fertilizers aSri Lanka aCoco aCocos Nucifera aFolha aNpk aCoconut aConcentracao de nutriente aFertilizacao aLeaf nutrients1 aBALAKRISHNAMURTI, T.
