The experiment was arranged in a completely randomized block design with one factor. There are two treatments: urea fertilizer not thawed (P1) and urea fertilizer thawed (P2). Each treatments were two replications, and each replications consisted of 2 sample plants so the total unit of experiments were 8 plants. Data were analized with analysis of variance with α 5 %, If there is a significant treatment effect, the further analysis using LSD (Least Significant Differences). The result showed that the fertilization of solid and liquid urea through biopories did not significantly affect for all variabels from the beginning to the end of the research and the application of solid and liquid urea fertilizer showed the same effectiveness for growth of five years old mature oil palm.]]>
