TUMPANGSARI TANAMAN KELAPA SAWIT (Elaeis guineensis Jacq.) dengan TANAMAN KARET (Hevea brassiliensis L.)

Abstract: Monoculture cultivation system has impact on various biotic  surrounding in it.  Palm oil cultivation with intercropping system started  to be popular to avoid environment damaged. Intercropping cultivation between palm oil and other plant was possible in existing both intraspecific and interspecific competation. Various form of this competation was needed to be learned. The compatible variables to measure these competation forms is Land Equal Ratio (LER) that able to compare the benefit between monoculture an… Show more

“…Luas areal perkebunan yang dimiliki petani sawit swadaya di Desa Upe, Kecamatan Bonti, Kabupaten Sanggau secara keseluruhan kurang dari 5 Ha dengan status kepemilikan lahan sertifikat hak milik serta ditanam dengan pola monokultur dengan hasil produksi 1-5 ton dan tumpang sari dengan hasil produksi ≤1 ton. Menurut Nengsih (2016) produksi tanaman kelapa sawit sistem monokultur lebih tinggi dari sistem polikultur (tumpang sari) karena tanaman sawit yang ditanam dengan polikultur akan menyebabkan pertumbuhan lingkar batang kecil, populasi tanaman lebih banyak (melebihi populasi optimum) sehingga akan terjadi persaingan dalam hal penyerapan unsur hara dan air dalam tanah dan persaingan mendapatkan sinar matahari yang dibutuhkan untuk proses fotosintesis.…”
