Abstract

Abstract This study aimed to assemble a super mini hydroponic from small used plastic bottle and determine the influence of different concentrations of phosphorus for the growth of Ipomoea reptans in super mini hydroponic. The methodology of this research was the Research and Development (R&D) and used a Completely Randomized Design (CRD) with three different concentrations of ABmix pure, ABmix+12.6 g of phosphorus, ABmix+ 16.2 g of phosphorus). The data were analyzed by ANOVA using model of CRD on the growth of Ipomoea reptans . ANOVA results showed that the difference in phosphorus concentration significantly affected root length, plant height, number of leaves, fresh weight and dry weight. However,the different concentrations of phosphorus  didn?t significantly chlorophyll level. Duncan?s mean separation test at ? = 5% indicated that the treatment I (ABmix pure) was significantly higher when compared to treatment II (ABmix+12.6 g of phosphorus) and treatment III (ABmix+16.2 g of phosphorus).   Keywords: Phosphorus, ABmix, Gowth, Ipomoea reptans, Super Mini Hydroponic
