Abstract

The objective of this research was to determine the effect of two kinds and dosages of herbisides on growth of weeds on immature rubber {Hevea brasiliensis Muell. Arg) crops. The research was carried out in Research Station of Agriculture Faculty, University of Sriwijaya. The research started from March 2013 until June 2013. The method of this research Randomized Block Design (RBD) which was arranged in factorial 2 x 3 so that there are 6 treatments with 4 replications. The first factor were herbicides (H): Isopropilamina Glyphosate (Hl) and Metsulfuron Methyl (H2). The second factor were dosages (D) of Isopropilamina Glyphosate and Methyl Metsulfuron: 1 liter of formulation ha’1 (DI) and 50 grams ha’1 (DI), 2 liters of formulations ha'1 (D2) and 100 grams ha'1 (D2), 3 liters of formulations ha'1 (D3) and 150 grams ha’l(D3). The results showed that herbicide factors have the significantly effect to the variable of weed cover percentage on 60 days after application, the dose factors significantly affect the percentage cover of weeds variables 75 days after application, dry weight o f weeds 60 days after application and dry weight of weeds 75 day after application. The aplication of Isopropilamina Glyphosate 2 1/ha dosages and Methyl Metsulfuron 100 grams dosages have more influence to the percentage of weed coverages.
