Abstract:
Objective: The objective of this research was to study the growth and yield of Atlantic Potato cultivar grown in medium altitude areas with different amount of watering. Methodology: This study was conducted in search station of Agriculture Faculty of Padjadjaran University located in Jatinangor at the altitude of 685 m.a.s.l., at D3 rainfall rate in Inseptisol soil. A split plot design was used during the experiment. The main plot factor was using paclobutrazol at 3 different levels of concentrations (0, 50 and 100 ppm) and the second factor was watered at 4 different levels (100, 85, 70 and 55% water of field capacity). Results: The experiment result showed that applying 100 ppm of paclobutrazol could increase the tubers weight per plant, the starch content (12.50%) and reduce the sugar content (0.45%) for growing atlantic cultivar potato in medium altitude, however, it showed low height of the plants. The potato plants which were watered by 85% of field capacity showed the same height as ones watered by 100% while in other parameters low percentage of watering inhibited potato growth and its yield. Conclusion: Applying 100 ppm of paclobutrazol could increase the tubers weight per plant, starch content (12.50%) and reduced its sugar content (0.45%) other than that low percentage of watering inhibited potato yield for growing atlantic cultivar potato in medium altitude.
