Abstract
Oil Palm (Elaeis guinensis Jacq) is a plantation crop which playing an
important part for Indonesia, as a reliable commodity to export and also for the
commodity which expected can raise the farmer earnings. Oil palm has an
important meaning to increase the state's stock exchange and also can create a
work opportunity for the society. This can be seen from the oil palm plantation
area width which progressively increases especially in Riau Province, as noted
from 2001. This research is executed experimentally using the factorial group
random device (GRD) which consists of 2 factors. The first factor is a
Trichoderma SP dose and the second factor is Dregs dose, in each treatment
factor there's 4 levels so obtained 16 treatments combination with 3 repetitions, so
obtained 48 attempt units. Each attempt unit consists with 2 plants so the amounts
of all plant seeds are 96 poly bags. The parameter which observed are the C/N
analysis after the incubation of Trichoderma SP, the pH analysis, the absorption
of N, P, and K at the plant net, the accretion of seed height (cm), the accretion of
bar hump diameter (cm), the accretion of leaves stem amount (sheet), the plant dry
weight, and the root protrude ratio. The data which obtained is analyzed using the
Various Examination and then is continued with DNMRT test at the level of 5%.
According to the research result is obtained that the giving of Dregs is
significantly influence to the ground pH and the plant dry weight but Dregs were
not able to improve the plant growth. Dregs is also effecting to the availability of
N, P, and K element both in the medium and the absorption of N, P, and K to the
plant. The best giving of Dregs is on 10 g/kg peat doses. The giving of
Trichoderma SP is effecting to the parameter of the plant height accretion and the
bar hump diameter accretion. The best giving of Trichoderma SP is on 25 g/kg
peat doses.
