Abstract

This paper aims to find an optimal combination of gibberellic acid concentration (C) and soaking duration time (T) in order to speed up and to improve the productivity of konjac (Amorphophallus muelleri Blume) germination process. For this purpose, a laboratory experiment was carried out with five levels of C and four levels of T. For each combination of C and T, 300 seeds were planted in three germination trays. And by using completely randomized design, in each tray, 100 seeds were planted. On the day right after a number of days after planting (D) which consists of seven levels, the germination rate is then recorded. By using data analytics method, we conclude that the optimal combination of C, D and T is C = 200 ppm, D = 7 days and T = 6 jam. Meanwhile, for a given T and D, concentration has no effect on germination rate. It is worth noting that (i) the experiment was conducted at room temperature under controlled humidity level, and (ii) according to the knowledge of the authors, this is an unprecedented study where Gibberellic acid is applied on konjac.
