Abstract

This experiment has an object to study the response of four potato cultivars to paclobutrazol and paranet shade application in medium plain. Land height is about 700 m about sea level and experimental design in use is Split-Split Plot Design. Three factors used as treatment in this experiment are paranet shade of without shade (0%), shade of 30%, and 50%, four cultivars potato (Granola, Atlantic, Spunta, dan Raja) and regulator, Paclobutrazol (0 ppm, 50 ppm, and 100 ppm). The result shows interaction between paranet shade, cultivar, and paclobutrazol are affecting to height of plants. Interaction between paranet shade and paclobutrazol is affecting to tuber amount. Cultivar Atlantic with 50% paranet shade without application paclobutrazol shows tallest plants that is 69,33 cm and the shortest is 33,83 cm at cultivar raja without paranet shade and application paclobutrazol 100 ppm. The results of this research proved that the growth of potato affects by cultivar, paranet shade, and paclobutrazol application. The best observed plant height of potato was Atlantic cultivar attempted with 50% density of shade without paclobutrazol application. Moreover, Atlantic cultivar showed higher Leaf Surface Area Index (LAI) and Net Assimilation Rate (NAR) value. Otherwise, the best yield was showed by Granola cultivar, so Granola can be counted as adaptable cultivar in medium plain.
