RESPON PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq) TERHADAP PEMBERIAN DOLOMIT DAN PUPUK FOSFOR
ABSRACT: The experiment aimed
to identify the growing of palm oil seedling (Elaeis guineensis Jacq) upon the
aplication of Dolomite and Phosporus fertilizer, as well as its interaction,
and to find the proper dosage of dolomite and Phosporus fertilizer for palm oil
seedling. The experiment lasted for four months, from Oktober 2010 to Januari
2011, at the screen house agriculture faculty Widya Gama Mahakam university,
Sempaja Samarinda City. The experiment employed Completely Randomized Block
Design with Factorial 3 x 4 and three replications. The first factor was
Phospor fertilizer (P) : 1,5 g SP-36/polybag (p 1 ); 2,0 g SP-36/polybag (p 2
); 2,5 g SP-36/polybag (p 3 ). And the second factor was dolomite (D): no
dolomite (d 0 ); 10 g dolomite/polybag (d 1 ); 15 10 g dolomite/polybag (d 2 );
20 g dolomite/polybag (d 3 ) . Results
at the experiment showed that: (1) significant responses of phosphorus
fertilizer on the parameters of number of leaf at the stage of 90 old days and
diameter of stem at the stage of 60 old days; (2) significant responses on the application
of Dolomit on diameter of stem at the stage of 30 and 60 old days; (3)
significant responses the interaction between phosporus fertilizer and Dolomit
application on number of leaf at the stage of 60 old days.
