Pengaruh penambahan bioaktivator, asam humik dan mikoriza (CMA) terhadap pertumbuhan kaliandra merah (Calliandra calohyrsus)

Abstract

The aim of study are to determined the effect of application by combined bioactivator and humic acid at different level with or without mycorrhiza on growth and production of Caliiandra calothyrsus. A factorial completely randomized design was applied in this study, which consisted of 2 factors (2x5) and replications, many kind of bioactivator that used in this research are bioenzim and bioc-α. The first factor was mycorrhiza additions (0 and 20 g/polibag) and the second factor was humic acid addition (D0=0 g, D1=5g, D3=7.5 g, D4=10 g). The data were analyzed with analysis of Variance (ANOVA). Duncan Range Test were used if there is any significant effect. The experimental result showed that combination by bioc-α, humic acid and mychorrizae effected significantly vertical length gain, number of branch, stem diameter, total production root dry matter and root infection percentage. Interaction between of bioc-α and 10 gram humic acid with mycorrhiza give the best result to increase growth factor Calliandra calothyrsus.
