  • The overall goal of this experiment was to establish a technology for growing potato at the lowelevation. There were three groups of experiment with its own separate objective. The first experiment was to determine the best time (1, 2, 3, and 4 week after emergence) for applying retardant at their effective concentration (4 ppm ANZ, 1200 ppm CCC, 50 ppm COU, and 4000 ppm PBZ) for. promoting potato tuber formation. The second experiment was to determine the best combination of time for watering potato crops and time for applying retardant (Coumarin) to promote tuber formation. The third experiment was to find out the best mulch type in reducing soil temperatures. Results showed that each retardant had its own best timing for application, 12:00 WIB was the best time for watering potato crops, irrigation significantly reduce maximum soil- temperatures, and silver mulch along with organic mulches were the best mulches for reducing maximum soil temperature.
