| dc.description.abstract | This study aims to determine the effect of fertilization and land slope on oil
palm productivity at PT Perkebunan Nusantara IV Pabatu unit in Serdang
Berdagai Regency, North Sumatra, conducted from May 2023 to June 2023. This
study uses secondary data available in the plantation administration, including
productivity data in 2015, 2016, 2017, 2018, 2019, 2020, 2021, and 2022, NPK and
Mg fertilization data in 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, and land
slope data taken directly. The analytical methods used were multiple linear
regression analysis and correlation analysis. The model was tested for feasibility
with classical assumption tests including normality, heteroscedasticity test,
multicollinearity test, and autocorrelation test using SPSS.v.22 for windows
statistical tools. The results showed that NPK and Mg fertilization had no
significant effect on increasing oil palm productivity. Land slope has a real effect
on increasing the productivity of oil palm productivity with the more land
approaching flat conditions (0°) the higher the productivity of oil palm produced.
The correlation of NPK and Mg fertilization has a weak influence in achieving oil
palm productivity. The correlation of land slope has a significant effect on oil palm
productivity. | en_US |
