One of the obstacles faced in oil palm cultivation, especially in the immature plant phase, is weeds, weeds can inhibit oil palm growth. So that weeds require special attention during cultivation, the presence of these weeds will become competitors for oil palm plants in fulfilling nutrients, light and water. This study aims to determine the composition of the types and vegetation structure of weeds in immature oil palm plants in large plantations so that the dose of herbicide with active ingredient Methyl Metsulfuron 20% is effective in controlling weeds in immature oil palm plantations in large plantations and studying the phytotoxicity of herbicides made from 20% active Methyl Metsulfuron in immature oil palm trees in large plantations. This study used a randomized block design (RBD), which consisted of 7 levels of treatment, 5 of which used the herbicide methyl metsulfuron 20% at a dose of 87.50 g / ha, 75.00 g / ha, 62.50 g / ha, 50.00 g / ha, 37.50 g / ha. ha and 2 including mechanical and control weeding which is repeated 4 times. Data analysis was performed with the F test, followed by the DMRT test at 5% level. The results showed that there were two species of weeds that dominated the research area, namely B. mutica and A. gangetica weeds with SDR values of 33.13% and 24.73%. The application of herbicides made from 20% methyl metsulfuron as active ingredients in controlling weeds in immature oil palm plantations is able to control 2 types of weeds, namely weeds including Melastoma malabathricum, Clidemia hirta with the best dose of 50.00 g / ha and 37.50 g / ha from the first 4 weeks up to 12 Weeks After Application (MSA).

“…Gliricidea sepium merupakan jenis pohon legum cepat tumbuh, banyak kegunaannya seperti pakan ternak (Winata et al, 2012), kayu bakar (Atapattu et al, 2017), sebagai pohon penaung dapat memberikan naungan antara 66 -80 % (Sobari et al, 2012;Kumalasari et al, 2019), sifat yang adaptif terhadap berbagai jenis tanah maupun suhu, sehingga jenis ini sesuai untuk dijadikan sebagai tanaman penaung dalam revegetasi tambang (Mansur, 2013;Ghosh et al, 2017). Gliricidea sepium dilaporkan telah digunakan untuk reklamasi lahan bekas tambang emas (Wijayanti et al, 2020), pasir (Putra et al, 2014), timah (Narendra & Pratiwi, 2016), dan batubara (Setyowati et al, 2017).…”

Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.
