PENGARUH TOPOGRAFI LAHAN TERHADAP PRODUKTIVITAS KELAPA SAWIT (Elaeis guineensis Jacq.) DI PT. DHARMA INTISAWIT NUGRAHA MUARA WAHAU KABUPATEN KUTAI TIMUR

Abstract

Oil palm is one of the potential commodities whose cultivation trend began in 2003 in East
Kalimantan which has the characteristics of hilly land. Oil palm itself is preferable to grow at an
altitude of 400 m asl with a slope of up to 23% or at 12°.Therefore, this research is motivated to
determine the yield of oil palm plantations in certain land slope classifications. The study was
conducted on 2 afdeling which have different land classifications with an area of ± 14,000 ha.Then
for comparison, it was taken through production data in 2019 with 2 treatments and 12 replications,
which were processed using Analysis Of Variance (ANOVA) Two Way Anova. Primary data were
obtained through field observations, as well as soil sampling, which were analyzed directly for soil
physical properties and laboratory for chemical properties including pH H2O, Nitrogen (N),
Phosphorus (P), Potassium (K) and Magnesium (Mg.). The results of the research on the effect of
slope on oil palm production by various methods indicate that the land slope factor does not have a
significant effect on oil palm productivity.
