$aThe stemflow, throughfall and interception patterns of coconut plantations in La Union at various age classes (0.1-5.0, 5.1-10.0, and 10-15 years old) were evaluated to develop appropriate predictive models for the hydrologic processes considered of the age-classes selected. The total rainfal collected from the study area for a 1 1/2-year period amounted to 3,112.40 mm. For 1981, September had the highest rainfall and number of days (455.60 mm and 17 days) and July 1982 with 831.10 mm and 28 days, followed by August with 714.90 mm and 25 days. Most of these rainfall occurences were due to the intensification of the southwest monsoon and several tropical cyclones. Age class 0.1-5.0 years old produced the highest throughfall with 74% total rainfall, followed by 10-15 years old age class with 0.069% total rainfall. The throughfall catch variation among coconut tree age classes was not significant. There was a linear relationship between throughfall and total rainfall. Stemflow was highest in age-class 0.1-5 years old with 75.48% of the total rainfall. No significant variation in stemflow catch by the coconut trees was apparent. The relationship of total rainfall to stemflow in all the treatments showed a direct trend. Net rainfall did not vary considerably among the coconut trees of various age-classes with the youngest classes producing the highest net rainfall (1,773.94 mm) and the oldest class the least net rainfall (614.42 mm). There was no significant difference in interception loss produced by the various coconuts at various age classes. The older and taller coconut trees with greater number of spirally drooping leaves intercepted greater amount of rainfall that later evaporated, while younger trees intercepted less amount of rainfall, of which a greater amount reached the ground for soil moisture recharge. Linear regression models to predict each parameter have been derived. Future studies should be done in at least four years to complete one-climatic cycle, and should use improved instrumentation techniques for accurate and better results.
