        Abstract

        The objective of this research was know the effectivity of glyphosate combined with methyl metsolfuron and to determine mixturing rate dosage for controlling weeds growth on mature oil palm at Melania Plantation. Research was conducted during August until November 2006 at PT Melania Indonesia, banyuasin site. G1 = 480 g a.i ; G2 = 720 g.a.i ; G3 - 960 g.a.i. glyphosate ha-1. the second factors are rate dosage methyl metsulfuron M0 = 0 h.a.i M1 = 10 g.a.i; M2 = 15 g.a.i. and M3 = 20 g.a.i methyl metsulfuron ha-1 respectively. The result of research showed that combination of glyphosate and methyl metsulfuron may increase herbicides effetivity on controlling weeds on oil palm plantation. Mixturing of glyphosate (480 g a.i. ha-1) with methyl metsulfuron (10 g a.i. ha-1) reduced dry weight of Clidemia hirta and Nephrolepis bisserata. Application glyphosaet on rate dosage 960 g. a.i. ha-1 gave result with the lowest dry weight of Ottochloa nodosa. The other side application methyl metsulfuron 10 g.a.ki ha-1 have suppressed dry weight of Clidemia hirta and Nephrolepis bisserata. Weed density assessment was done before herbicide application research area there were dominant weeds such as Ottochloa nodosa, Clidemia hirta and Nephrolepis biserrata with summed dominant ratio (SDR) value 45,24%, 15.84% and 10.95% respectively.
