APLIKASI KOMPOS YANG DIPERKAYA DENGAN BERBAGAI BAHAN UNTUK TANAMAN KEDELAI (Glycine max L. Merril) DIANTARA TANAMAN SAWIT MUDA DI LAHAN GAMBUT
Abstract: The total area of
oil palm plantations in Indonesia about 7 million in Riau which is about 3
million ha. Land has not been optimally covered by oil palm crop of young (aged
approtimately three years), so that they can be planted with soybean as
intercrops in oil palm plantation . The research was conducted in the village
of Kualu Nenas, District of Kampar, Riau Province. The research aims to study
to the effeet of the application of mixture of compost of oil palm empty fruit
bunches, boiler ash, liquid waste of palm oil mill and trichoderma growth and yields of soybean in oil palm plantations on peatland. The
study was conducted through an experimen using randomized block dising (RBD),
which consists of 8 treatment A : Without treatment, B : 5 tons of compost of
OPEFB/ha, C : 5 tons of compost of OPEFB + 0.5 tons of boiler ash/ha, D : 5
tons of compost of OPEFB + 1 boiler ash/ha, E : 5 tons of compost of OPEFB +
1,5 boiler ash/ha, F : 5 tons of compost of OPEFB + 0.5 tons of boiler ash + 10
kg trichoderma + 30 L liquid waste of palm oil mill/ha, G : 5 tons of compost
of OPEFB + 1 ton boiler ash + 10 kg trichoderma + 30 L liquid waste of palm oil
mill/ha, H : 5 tons of compost of OPEFB + 1.5 tons boiler ash + 10 kg
trichoderma + 30 L liquid waste of palm oil mill/ha, each repeated three times.
The parameters observed were plant height, number of primary branches number of
pods, pod percentage pithy. The results showed that treatment G : 5 tons of
compost of OPEFB + 1 ton boiler ash + 10 kg trichoderma + 30 L liquid waste of
palm oil mill/ha, increased plant height and number of pods significantly
compared with without treatment, but not significantly different to the
parameter number of primary branches, days to flowering and pod percentage
pithy.
