Summary : One year onservation showed that the growth of pineapple grown as intercrop with coconut was greatly improved by application of NPK fertilizers. On the other hand, NPK fertilizer did not improve the growth condition and yield of coconut. Increased NPK rates resulted in a significant increase in N concentration, a significant decrease in P content and a slight decrease in K percentage in pineapple leaves. The NPK concentrations in pineapple leaves differed significantly with the periods of leaf sampling. N concentrations in coconut leaves and meat were slightly higher in plots fertilized with higher rates of NPK. P and K percentage in all the tissues analyzed were not significantly affected by NPK fertilization. Likewise, the periods of sampling did not consistently affect the NPK concentrations in the tissues.
