Pengujian LCC Mucuna bracteata di Berbagai Kemiringan Lahan Terhadap Perkembangan Mesofauna Tanah dan Akar Kelapa Sawit TBM - III
Abstract: The purpose of this
study was to determine the effect of LCC Mucuna bracteata in various slope on
the development of soil mesofauna and growth of oil palm TBM - III. This
research has been conducted in PTPN V Unit Lubuk Dalam, Siak and analysis
mesofauna soil in Soil Laboratory, Faculty of Agriculture, University of Riau.
The study lasted from January to April 2016. The study was conducted by using
split plot design. The level of slope (K) as the main plot, which are: K1 =
land slope of 0% - 3%, K2 = land slope >3% - 8%, K3 = land slope >8% -
15%. Testing 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. The parameters measured were the number of family,
total individual, population density (K), relative density (KR), diversity index
(H ') of soil mesofauna, root dry weight, root volume and root occupy. The
results showed: (1) land planted with oil palm with LCC Mucuna bracteata has a
number of families, total individuals and diversity soil mesofauna higher in
than those without LCC Mucuna bracteata both at the level of land slope 0% - 3%
>3% - 8% , and >8% - 15%; (2) The higher the slope (%), the total
individual and population density (K) soil mesofauna lower; and (3) root dry
weight, root volume and root occupy a tendency to increase the area planted
with Mucuna bracteata LCC compared to land without LCC Mucuna bracteata.
