Pengaruh Mucuna bracteata dan Kemiringan Lahan Terhadap Keragaman Makrofauna Tanah serta Pertumbuhan Akar Tanaman Kelapa Sawit Belum Menghasilkan
Abstract: The aimresearchof
determine the influence of M. bracteata and the slope of land to the diversity
of soil macrofauna and root growth of oil palmsimmature. This research was
conducted in PTPN V Unit LubukDalam, Siak and analysis of soil macrofauna in
the Soil Laboratory Faculty of Agriculture, University of Riau. This research
has been carried out from January to April 2016. The study was conducted using
Split Plot Design. The level of the slope (K) as the main plot consists of: K0
= 0-3%,K1 =>3-8%, K2 = >8-15%. Employing Mucunabracteata (M) as the
subplot consisting of: M0 = land clearning, M1 = land that is overgrown. The
parameters measured were the number of population density, relative density,
diversity index (H’) soil macrofauna, root dry weight, root volume and root
occupy. The research showed: (1) land overgrown palm M. bracteata has a
population density number, relative density and the diversity of the soil
macrofauna higher and better root growth compared with that land clearning; and
(2) The higher the slope (%) resulting in a population density, relative
density and the diversity of soil macrofauna are getting lower and root growth
decreases.
