Abstract
Some Dominance Ratio (SDR) is the quadrant method that is one of the vegetation analysis used to find out the weeds that dominate the oil palm planting area which is the determinant in the implementation of control. The research objectives were to find out of the types of weeds that had grown dominantly in the oil palm plantation at collecting point area, the pathway, and on the circle area on peat soil based on SDR values and compare those values. The method in this study is the quadrant method for analysis of weed vegetation and t test. The research was carried out in the oil palm and mineral soil areas of PT Sampoerna Agro in North Sumatra. The results showed that the types of weeds that had grown dominantly in the oil palm plantation on block 16 C were Kentosan, Axonophus compressus, Cyrtococcum accrescens, and Borreria alata. Kentosan and Axonopus compressus had grown dominantly in collecting point area with SDR values of 30%, and 70%. Borrearia latifolia and Borreria alata had grown dominantly in the circle area with SDR value of 24%. Axonopus compressus and Cyrtococcum accrescens had grown dominantly in the path area with SDR value of 29%. The results of the t test carried out on the SDR of all types of weeds on the circle, on the path and in collecting point showed significantly different results
