Uji Mulsa Organik Terhadap Gulma Dan Produksi Kacang Hijau (Phaseolus radiatus L.)
Abstract: We experimentally studied
the effect of
organic mulches on
weeds and yield
of green beans (Phaseolus radiatus
L.) have been
conducted at green
house and Laboratory
of Plant Ecology, Departement of Biology, Faculty of
Natural Sciences, Andalas University, Padang, from January to May 2014.
The aims of
this study were
to determine the
effect of different
mulches (Mikania micrantha and
Tithonia diversifolia) on
weeds and yield
of green beans.
The experiment used nested design with eight treatments and
three replications. The first factor (factor A) was two kinds of mulch (i.e
Mikania micrantha and Tithonia diversifolia). While the second factor (factor
B) was the given doses of mulch (i.e 0 g/polybag, 300 g/polybag, 600 g/polybag
and 900 g/polybag). The results
showed that Mikania
micrantha mulch gave
the stronger effect
to reduce weed
numbers. Mikania micrantha
mulch on
900 g/polybag increased
plant height and
Mikania micrantha mulch on
300 g/polybag increased
seed yield. Whereas
Tithonia diversifolia mulch
on 600 g/polybag increased plant height and the
number of primary branches and Tithonia diversifolia mulch on 300 g/polybag
increased seed yield.
