Abstract
An effort to raise the crown production can be done by extend the land of
histosol. The main problem always faces by the farmer in using the land of histosol
is the high of acid (low pH). To make it can be used to farm better is by giving
ameliorant such as dregs. The purpose of research is to get the best dosage to the
growing and the production of com. It is done on April to Agust 2007 at the land
of histosol, Rimbo Panjang Village of Kampar. The research is done by experiement
with random complete methode /Rancangan Acak Lengkap (RAL). It consits of 5
stages with 3 repetition at every stage. They are Do (without giving dregs), Dl
(5 tons ciregs/ha=3^ kg/plot), D2 (10 tons/ha=7 kg/plot) D3 (15 tons/ha=10.5 / plot)
and D4 (20 ton/ha =14 kg/plot) it consist of 15 plots, every plot has 32 trees. The
parameter is about the fastest growing tree, height of the dried structure of tree,
emerging time of male and female flower, length and diameter of com, sum and
height of seed for every com and height every 1000 seeds. The result of research
shows that giving 15 tons dregs/ha can raise the growing and height and* it can
make fast grow to the flower. The length and the sum of seed for every com tend
to raise by giving every dosage of dregs. By giving 5 and 15 tons dregs/ha can raise
the height of seed for every com and height of 1000 seeds.
