A weed is a plant that is considered to be nuisance and unwanted plant in human-controlled settings, especially farm field and garden. The weed that grow in surounding of crop could decrease yield due to competition occur between weed and crop on nutrition, sunlight and water. Organic cfarming system which has been developed nowadays is an environmental friendly organic farming system. The objective of this research is to determine weed competition on carrot using several kinds of organic fertilizer. Six treatments were used in this research, i.e., green manure, combination of green maure and EM4, EM alone and control (without manure and EM). The weed was growth together with carrot for three months. The parameters are wet weight and dry weight of carrot per meter square. The results show that manuring could increase weed competition between carrot and weed occured in the treatment of combination between organic manure which combines with EM. The added EM on organic manure could increase weed competition on carrot
