Abstract

The growth and productivity of two Water Spinach varieties (Kankung Unggul BikaR and Kangkung Bangkok LP-1R) had already been experiment on two different Hydroponic culture subsystems (Floating Raft and Pumice Bed) of an Aquaponic system, where mineral nutrients of the Water Spinach vegetables were absorbed from bio-chemical processes in solid wastes of fish and excess feeds. Consequently, this study showed individual functions of these two different Hydroponic subsystems from new established dates no significant differences on the 7 date of testing. Until increasingly significant difference for the Hydroponic subsystem of Floating Raft is less effective than Hydroponic subsystem of Pumice Bed based on the length of shoot, length of petiole, width of leaf on the 14 test date and the length of shoot, length of petiole, length of leaf, the number of leaves and length of root on the 21 test date. Nonetheless, Hydroponic subsystem did not support the growth and productivity of the Water Spinach varieties in all stages of testing about statistical significance. In addition, in term of productivity and growth criteria on the 7, 14 and 21 dates of testing, no significant difference was observed between two Water Spinach varieties. Finally, the advice of this study does not reassess the treatment (Floating Raft Hydroponic subsystem and Kangkung Unggu BikaR variety) because of the poor result of length of shoot, length of petiole and reality of yield for this Kangkung Unggul BikaR variety are probably at the 21 date.
