PERBEDAAN KONSENTRASI FOSFOR TERHADAP PERTUMBUHAN BAYAM HIJAU PADA HIDROPONIK SUPER MINI

Abstract This study aimed to determine the influence of different concentrations of phosphorus for the growth of green spinach plants (Amaranthus viridis L) grown in super mini hydroponic. This study used a completely randomized design (CRD) with three different concentrations of phosporus (AB mix, AB mix+12, 6 g SP-36, and AB mix+16,2 g SP-36). The data were analyzed by ANOVA using model of CRD on the growth of green spinach conduted for 4 week. ANOVA results in the super mini hydroponic trial showed that the differences in phosphorus concentrations did not significantly affect the number of leaves, wet and dry weight, but the effect was on root length, plant height and chlorophyll contents. Duncan's mean separation test at α = 5% indicated that the concentration of phosphorus treatment II (12.6 g) in root length, plant height, and chlorophyll levels were significantly higher when compared to the control of phosphorus and phosphorus treatment III (16.2 g).
