Potato Productivity (Solanum tuberosum L.) of G0 Granola L. Varieties at Different Planting Distance and Temperature Grown in Aeroponics

Abstract

Purpose : Both quantity and quality potato seed production in Indonesia is relatively low, because it is still cultivated conventionally. Aeroponic cultivation can produce seeds in large quantities and quality with environmental control through setting the spacing and temperature regulation of the rooting area (room box). This research was to study the increase in productivity of G0 type potatoes at planting distance and the room temperature of the box. Research Method : The research to study the productivity of G0 type potatoes at different planting distance (j0: 20 cm x 20 cm, j1: 20 cm x 25 cm, and j3: 20 cm x 30 cm), and the room temperature of the box (t0: room temperature (control) and t1: 150C. The experiment was set up as randomized block design and repeated 4 times. Data were analyzed for variance and Duncans’ further test. Findings : The results showed no interaction between planting distance and temperature. The planting space of 20 cm x 20 cm gave a significant effect on plant height at the age of 45 DAP. The temperature treatment of 150C has a significant effect on plant height at 15, 30, 45 and 60 days after planting (DAP), a number of leaves at 15 and 45 DAP, and the number of potential tubers. Limitations : Limititations in this research was that harvest time was not optimal because due to the plants inability to continue their lives due to wilting disease and high air temperatures. Value : Information from this research is very important for potato seed farmers in increasing crop productivity by managing temperatures to cool down at night in the rooting area.
