PENGARUH TAKARAN MEDIA BALITHI TERHADAP PERTUMBUHAN DAN PRODUKSI DAUN LEATHERLEAF FERN (Rumohra adiantiformis) (G.Forst.) Ching)

Abstract

Leatherleaf fern (Rumohra adiantiformis) could be the cut leaves of ornamental plants as a filler and
bouquet. Growing media is one of the important factors to produced growth and yields of leatherleaf.
The research aims to study the effects of several dosage Balithi’s media could support to maximizing
growth and yields of leatherleaf. The research was conducted at IOCRI (Indonesia Ornamental Crop
Research Institute) in June 2014 - December 2015. Experiment used a randomized block design
(RBD) two factors with four replications. The size of each plot treatment was 1.2 × 2.1 m. The first
factor was the Balithi’s media, namely: 1 dosage Balithi’s media without gliocompos (M1), 1 dosage
Balithi’s media with gliocompos (M2), and ½ dosage Balithi’s media with ½ dosage gliocompos
(M3). The second factor was the leatherleaf varieties, namely Florida (V1) and Mayfield (V2). The
result showed that treatment variety was significantly affected the parameters of crown height, length
of strands and number of leaves per plot. The varieties Mayfield growth better than Florida. The
Mayfield variety produced 3,961 strands and Florida variety 2,160 strands. M3 was the best media;
M3 produced 1,268 leaves, M2 1,082 leaves and M1 1,067 leaves. The best media for growth and
yields was M3 (½ dosage Balithi’s media + ½ dosage gliocompos).
