Abstract

The research aimed to know the species weeds of rice, weed dominance, biomass production, and nutrition, on sawah ecosystem around pesisir was conducted at Kecamatan Sungai Serut Kota Bengkulu from May 2009 until July 2009. Fifty plots 1 m x lm were used in the research. The weeds were harvested, than determine species of weed, the number of species and the number of individually of species, biomass production, nutritive value, dominance of each species, and its distribution. The result of research indicate that there are twenty three species of weed rice. Fymbristilis milliaceae, Lindernia anagalis, Cyperus halpan, Ludwigia perennis are weed of rice have high value of SDR that as 18.30 %, 11.92%, 10.82%, 8.94%, 7.55%, and biomass production 495.96 kg/ha or 27.87 %, 206.2 kg/ha or 11.15 %, 127.9 kg/ha or 7.19 %, and 94.08 kg/ha or 5.29 %. The value of calcium are 0.02%, 0.09, %, 0.13%, 0.08 %, 0.06 % and the value of crude protein are 5.28%, 6.89%, 5.97%, 6.01%, and 7.39% weeds are potentially as animal feed.
