Uji Pemberian Kompos Azolla microphylla Pada Pertumbuhan Bibit Karet (Hevea brasiliensis) Stum Mini
Abstract: This study aim to
determine the effect of compost on the growth of Azolla microphylla PB 260 clone rubber
seedlings mini stump. This research has been conducted at Agriculture Faculty,
University of Riau starting from April to July 2013. The research was carried
out experimentally using completely randomized design non factorial consisting
of 4 treat ments and 3 replications,
obtained 12 experimental units and each unit consists of 3 seeds so that total
earned is 36 rubber seedlings and as sample 2 seedlings per unit experiment.
Compost treatment given to the provision of
treatment levels; 0, 15, 30 and 45 g/polybag (0, 10, 20 and 30 ton/ha)
mixed by weighing soil 3 kg. The data were statistically analyzed using
analysis of variance, followed by Duncan's test New Multiple Range Test (DNMRT)
at the level of 5%. Parameters observed are lenght of grafting (cm), stem graft
girth (cm), number of leaves (sheet), leaf area (cm²) and shoot root ratio (g).
Giving Azolla microphylla compost on growing mini stump rubber seedling significantly effect on
extending the graft and number of leaves. Meanwhile, for stem graft girth, leaf
area and shoot root ratio reveal not significant. Compost dosing 30 g/polybag
shows the best results for the growth of rubber seedlings mini stump compared
them 0, 15 and 45 g/polybag.
