Growth characteristics and starch productivities of the sago palms growing in Pontianak, West Kalimantan, Indonesia were investigated. Sago palms were growing along the tributaries of the Kapuas River in semi-cultivated/cultivated states. There were two folk varieties, Bemban and Buntal (hereafter referred to as varieties), both of which are non-spiny types; the characteristics of the varieties were distinguished in features such as their suckering ability, crown angles, and trunk length and diameter. Both varieties were estimated to be 10-12 years from harvest. As a result of a sampling survey at the appropriate harvest stage (bolting to flowering stage), Bemban was significantly superior to Buntal in trunk length, leaflet length, width and area, and leaf area. There were no significant differences between the varieties in dry matter, total sugar, and starch percentages in the pith. Moreover, a varietal difference was also not observed in the pith dry weight; therefore, there was no significant difference in starch content (yield), although the starch content of Bemban (326kg) was slightly higher than that of Buntal (278kg). There were no differences between the two varieties in the macronutrient contents in the leaflet and pith except for the Mg content in the leaflet. We concluded from these results that the two varieties of sago palms growing in Pontianak were not significantly different in starch and macronutrient contents in pith, although some growth characteristics were significantly different.
