The weeding duration influencing biomass and carbon content of herbaceaous species. The objective of this study were to analyze biomass and carbon content of three herbaceaous species (Cyclosorus interruptus, Nephrolepis biserrata, and Digitaria didactyla) in terms of different wedding durations. The biomass of Cyclosorus interruptus  that weeded for 2, 3, and 4 weeks were 26.50 gram, 35.50 gram, and 27.00 gram in study plot sized 12 m2. Nephrolepis biserrata had biomass 15.38 gram (weeding period of 2 weeks), 15.28 gram (weeding period of 3 weeks), and 19.90 gram (weeding period of 4 weeks). Biomass content of Digitaria didactyla were 76.67 gram, 74.00 gram, and 190.00 gram for weeding periods 2, 3, and 4 weeks, respectively.  The carbon content of Cyclosorus interruptus with weeding periods of 2, 3, and 4 weeks were 0,062 ton/ha, 0,056 ton/ha, and 0,032 ton/ha, respectively. Nephrolepis biserrata had carbon contents of 0,067 ton/ha, 0,051 ton/ha, and 0,050 ton/ha in weeding periods 2, 3, and 4 weeks. The highest carbon content of Digitaria didactyla were that weeded every 4 weeks (0,223 ton/ha) compared than weeding periods 2 weeks (0,180 ton/ha) and 3 weeks (0,116 ton/ha).
