PERTUMBUHAN Aquilaria spp DENGAN PEMBERIAN PUPUK KANDANG DAN MULSA DI TANAH ULTISOL PADA LAHAN TERBUKA
ABSTRACT: In the first phase
of planting, Aquilaria spp. can only grow in the shade because these plants have
semitoleren properties. This condition makes the Aquilaria spp difficult to
grow in openfields. Thus, this research was conducted with the treatment of
manure and mulch. Thisresearch aims to investigate the influence of manure and
mulch on the growth of Aquilaria spp.which is planted on ultisol soil in open
fields. The research was carried out in an experimentfields of Tanjungpura
University in Desa Pak Laheng, Toho sub district, Mempawah region.The research
was done until the plant reached the age of 3 months, using a factorial
experimentwith randomised block design. The treatment started from plants
treated without fertilizer (P0), plants with 500-gram fertilizer (P1), and
plants treated with 1000-gram fertilizer (P2), as well aswith the second factor
on plants without mulch (M1) and plants treated with mulch (M2). Theresults
showed that manure gave a clear influence towards height accretion, leaf
accretion, and the increase in diameter. Meanwhile, mulch only gave influences
towards the increase of diameter. The interaction of both treatments did not
give any influence on the growth ofAquilaria spp.
