Abstract

The purpose of this research was to determine the structure, composition and level of weed species diversity in immature oil palm plantations (TBM) and producing palm oil (TM) in Manggaraya village, Tanjung Lago sub-district, Banyuasin district. The research was conducted from February to April 2018. Observation method, with sample sampling technique using purposive sampling with the quadratic method. Observation parameters were Density, frequency, Important Value Index (INP), and species diversity index. Research results were obtained. The composition of weeds in immature oil palm plantations (TBM) was found in 5 families, 12 species and 709 individuals. The oil palm weeds produced (TM) found 4 families, 9 species, and 537 individuals. The dominant weed structures in immature oil palm plantations (TBM) were Panicum repen, and Eleusine indica with INP values: 23.43, and the oil palm plantations produced were Mikania micrantha, with INP value: 31.57, and weed diversity index. on immature oil palm (TBM) 2.14, and the weed species diversity index for producing crops was 2.07. The level of diversity of gullma types of TBM and TM is categorized as moderate.
