Pengaruh Pemberian Amelioran Dregs pada Tanah Gambut Terhadap Pertumbuhan dan Akumulasi Logam Berat (Pb, Cr, Se, Ni) dalam Beras
ABSTRACT: This research aims
to determine to the effect of ameliorant dregs the growth of rice plants and
the accumulation of heavy metals Pb, Ni, Cr and Se. This study was conducted at
Agriculture Faculty greenhouses, University of Riau and also Soil Laboratory,
and Campus Bina Widya km 12.5 Kelurahan Simpang Baru, Pekanbaru lasted from

Completely Raandomized Design (CRD), consists of 4 treatment (0, 20, 40, 60
ton/ha). The result shows that the application dregs 20 tons/ha increased plant
height, maximum number of tillers, grain weight and pithy rice. Ameliorant
dregs dosing with doses of 20, 40 and 60 ton/ha reveal small influence on the
accumulation of heavy metals (Se and Cr) even may not be detected at all the
presence of heavy metals (Pb and Ni) the grain so there is poison in rice
plants.
