Abstract

A research about change of weed composition on ground peanut was conducted at the lndralaya farmer field Kabupaten Ogan llir from April to Agust 2001. Effects of fosfat fertilizer and plant number per hote were studied on change of weeds composition .. The experiments set up in a Randomized Completely Block Design. The treatment of fosfat fertilizer were 0, 45, 90, and 135 kg TSP and plant number were 1 and 2 per hole. Vegetation analysis was conducted to get varians of weed composition. At early of research before treatment, the dominant of weeds are Cylindrica, B. aiata and C. compressus. At early age of plant wich the dominant weeds was revealed that B. alata arai C.compres $U$, PY harvest of crop was dominated by I. Cylindrica and C. compressus.
