Abstract
The sago palm is known for its ability to accumulate starch in its stem and can grow in peat and mineral soils. However in the Philippines, the sago palm is mainly utilized as roofing material as a source of income. A study was conducted in Alubijid, Misamis Oriental, Mindanao, Philippines, to evaluate data on biomass, plant population density and to conduct income analysis derived from sago thatch production. Studies have shown that sago palm biomass resulted to measurements of leaf parameters since there was no trunk formation due to the cutting of 3 leaves every three months to produce the thatch and to remain 3-4 leaves per palm. The population density of palms per hectare was extremely high ranging from 3025 to 4600 palms. This further supports the fact that sago growing areas in Alubijid were flooded throughout the year and that farmers need to grow more palms to harvest more leaves thus controlling newly grown suckers has not been practiced. Recently, the prevailing market price of sago roofing material per 100 pieces is US $6.24. Based on the population density, sago farmers can roughly gain an annual net income of US $3,591.71 per hectare, which is higher compared with the net income of a local farmer.
