Pengaruh Mulsa Serbuk Gergaji dan Pupuk Npk Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis Jacq.) Pada Fase Main Nursery
ABSTRACT: This study aimed to
determine the effect of sawdust mulch and NPK fertilizer giving on the growth
of oil palm seedlings and to get the appropriate dose for the growth of oil
palm seedlings. This study has been conducted at the Experimental Garden
Faculty of Agriculture, University of Riau began in December 2012 until March
2013. The research was conducted in the experiment form with Completely Randomized
Design ( CRD ) which is arranged in factorial consisting of 2 factors, they
are: First factor is the standard dose of NPK Sigifertilizer which is
consisting P0=Without NPK fertilizer/polybag, P1=NPK dose 2 tablets/polybag,
P2=NPKdose 4 tablets/polybag, and P3=NPK dose 6 tablets/polybag. Second factor
is the giving of sawdust mulch consisting of M0=Without sawdust /polybag,
M1=dose giving sawdust 100 g/polybag, M2=dose giving 200g/polibag sawdust and
repeated 3 times, so it can be 36 units in the trial. Each experimental unit
consisting of 2 oil palm seedlings, so it takes 72 seeds. The parameters were
observed are the plants gain height, increasing number of leaves, increasing
tuber diameter, root volume, dry weight seedling and relative growth rate. NPK
fertilizer giving gave significantly different effect on seedling height
parameter and the number of leaves but did not give significant effect on tuber
diameter, root volume, dry weight seedlings and relative growth rate. The
combination of sawdust mulch giving 200 g/polybag with NPK fertilizer 4
tablets/polybag give the best seedling growth on the parameters of seedling
height, leaf number, root volume and dry weight.
