Introduction of Dwarf Elephant Grass (Pennisetum purpureum cv. Mott) and Annual Legumes in the Disused Limestone Mining in Karst Gombong Area, Central Java, Indonesia
Abstract: The aim of this
research was to revegetate the disused limestone quarry by introducing dwarf
elephant grass (Pennisetum purpureum cv. Mott) and annual legumes such as
peanuts (Arachis hypogaea L.), soybeans (Glycine max), cowpeas (Vigna
unguiculata) and mung beans (Vigna
radiata). The study was conducted experimentally in a disused limestone quarry
applying Completely Randomized Design. The research method used was
experimental in disused limestone mining in karst Gombong area applying
Completely Randomized Design (CRD). Treatment consisted of 6 planting methods
with 4 replicates. The 6 treatments research were the followings: RO: Single
planting of dwarf elephant grass, R1:
Single planting of dwarf elephant grass + 1.5 kg/m2 goat compost, R2: Mixture Planting of dwarf elephant grass
+ legume peanuts + 1.5 kg/m2 goat compost,
R3: Mixture planting of dwarf elephant grass + legume soybeans + 1.5
kg/m2 goat compost, R4: Mixture planting
of dwarf elephant grass + legume cowpeas + 1.5 kg/m2 goat compost and R5:
Mixture planting of dwarf elephant grass + legume mung beans + 1.5 kg/m2 goat
compost. The measured response variables were plant’s height, fresh yield, dry
matter yield and crude protein content of dwarf elephant grass aged 8 weeks.
The result showed that the addition of goat compost and the planting method of
annual legumes on the disused limestone quarry had highly significant influence
(P<0.01) on the increase productivity and quality of dwarf elephant grass.
The best method of planting dwarf elephant grass (Pennisetum purpureum cv.
Mott) on disused limestone mining in karst Gombong area is mixture planting with
soybean legumes (Glycine max) and adding the 1.5 kg/m2 goat compost.
