SIFAT FISIK TANAH DAN PERTUMBUHAN TANAMAN KARET (Hevea brasiliensis Muell. Arg) PADA BEBERAPA KONDISI PENUTUPAN LAHAN DENGAN Mucuna bracteata
Abstract: The objectives of
this research was to know the physical properties of peat soil and growth of
rubber plant on several ground cover condition by Mucuna bracteata at social
plantation area of PT. RAPP, Teluk
Meranti Subdistrict, Pelalawan Regency, Riau Province. Soil analysis was
carried out the laboratory of soil science Faculty of Agriculture, University
of Riau. This research was carried out from January to March 2016 and the
determination of the area of sampling arranged using purposive sampling methods
thats are sampling of rubber plant contained living mucuna, passed of mucuna,
and without mucuna. Variables observed in this research include of the soil
physical properties and observation of rubber plant. Observation of the soil
physical properties were soil colour, soil temperature, soil moisture, bulk
density, soil particle density, total pore space, soil permeability, and water
holding capacity. Parameter observed of rubber plant is circular stem. The
result showed that peat soil covered by living mucuna have soil physical
properties (soil moisture, soil temperature, and water holding capacity) higher
than passed of mucuna and without mucuna. At the rubber plant covered by living
mucuna also showed circular stem higher than rubber plant on the passed of
mucuna but on the passed of mucuna have circular stem higher than without
mucuna.
