Abstract

Abstract: Under high soil water levels, an imbalance occurs in the utilization of photosynthate between supporting vegetative growth and storage as starch. This results in a reduction in the density of dry matter in the stem and increased plant size. On the other hand, biomass yield and starch yield are considered to be low. This study examined the response of sago palm ( Metroxylon sagu Rottb.) seedlings to 50 and 80% soil water levels. To determine the response of the plant, several parameters were observed during the experiment: N, P, and K uptake, leaf photosynthesis, plant morphological growth, and sugar content in plants. It was found that the sago palm was able to show good growth performance under both 50 and 80% soil water levels. However, 50% soil water level is preferable due to trends in N, P, and K uptake, leaf photosynthetic rate, morphological growth performance, and also because no loss of starch is evident in the petiole or root. Core Ideas: Sago palm has prospects as a plant cultivated for land conservation and development in peatland. High groundwater levels promote a trend for higher photosynthetic rate of sago palm. Fifty percent soil water level is the most beneficial condition for supporting growth performance.
