PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) PADA MEDIUM GAMBUT YANG TERGENANG SECARA PERIODIK YANG DIPUPUK DENGAN PUPUK PELENGKAP CAIR DENGAN FREKWENSI YANG BERBEDA PADA SAAT BIBIT TIDAK TERGENANG
Abstract: This study aims to
determine the effect of giving PPC interaction with different frequencies when
not flooded in the medium periodically flooded peat on the growth of seedlings
of oil palm (Elaeis guineensis Jacq.). This research has been carried on in the
greenhouse UPT Faculty of Agriculture, University of Riau, Pekanbaru, from
November 2013 to February 2014. This study used a completely randomized
factorial design consisting of two factors and three replications. The first
factor is the concentration of PPC consists of 4 levels K0: no PPC, K1: 0.2%,
K2: 0.4%, K3: 0.6% and the second factor spraying frequency F1 PPC Consist 3
levels: 1 times, F2: 2 times, F3: 3 times. Parameters those observed: change of
plant height, increase the number of leaves, stem diameter, length of the
primary root, root number, root volume, the ratio of the shoot root ratio. The
data mean separation use DMRT at %. The results show that there is interaction
between the concentration and frequency of PPC spraying were the parameters
plant height, primary root length, shoot root ratio. A PPC concentration of
0.4% and 0.6% to add 3.17 to 3.78 of the leaves, concentrations of 0.4% and
0.6% to add 9.05 cm to 9.40 cm in diameter rod, concentrations of 0, 4% and
0.6% to add 15.22 to 16.55 strands strands, number of primary roots, a PPC
concentration of 0.2% to 0.6% shows the root volume amounted to 95.22 ml to
98.88 ml.
