Penggunaan Mucuna bracteata pada Berbagai Kemiringan Lahan Kelapa Sawit TBM-III dalam Rangka Perbaikan Sifat Fisik Tanah
Abstract: The purpose of this
study was to determine the effect using LCC Mucuna bracteata at various land
slope of palm TBM-III on soil physical properties and plant root growth of palm
oil. This research has been conducted in PTPN V Unit Lubuk Dalam, Siak and the
analysis of soil physical properties at Soil Laboratory, Faculty of
Agriculture, University of Riau. This study lasted from January to April 2016.
The research was conducted by using split plot design. The level of land slope
(K) as the main plot which are: K1 = land slope 0% - 3%, K2 = land slope >3%
- 8%, K3 = land slope >8% - 15%. The using LCC Mucuna bracteata (M) as the
subplot, which are: M0 = land planted with oil palm without LCC Mucuna
bracteata, M1 = land planted with oil palm LCC Mucuna bracteata. Parameters
observed are water content airy, soil temperature, bulk density, particle
density, total of pore space, permeability, soil organic matter, root dry
weight, root volume and root occupy. The results showed: (1) the interaction of
land slope and the using LCC Mucuna bracteata does not affect all of the soil
physical properties and the root growth of oil palm plantations, except for
water content airy in the soil depth 20-30 cm; (2) the land slope only affects
the water content airy in the soil depth 0-10 cm; and (3) the using LCC Mucuna
bracteata effect on water content airy, bulk density, particle density, total
pore space in the soil depth of 0-5 cm, permeability and soil organic matter.
