Abstract

This research was conducted in Aek Nabara village, Marancar district, South Tapanuli regency. This study aims to determine the production based on panicle level. Plant samples were taken from panicle level 1, panicle level 2, panicle level 3, panicle level 4, panicle level 5, panicle level 6, panicle level 7, panicle level 8, panicle level 9, and panicle level 11. From the results of the linear regression equation that the panicle level has a negative effect on the production, meaning that the higher the panicle level, the lower the production of juice and sugar . The highest sap production was found at the 6 panicle level (4,48 liters) and the lowest sap production was found at the 2 panicle level (1,04 liters). While the highest sugar production was found at the 6 panicle level (0,54 kilograms) and the lowest sugar production was found at the 11 panicle level (0,14 kilograms).

Keywords: sugar palm, panicle level, productivity.
