Abstract
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 surrounding of crop could decrease yield due to competition
occur between weed and crop on nutrition, sunlight and water. Organic farming 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 manure and EM, EM alone and control (without manure and EM). The weed was
growth together with carrot for 3 months. The parameters are wet weight and dry weight of carrot per meter square.
The results show that manuring could increase weed competition which in turn wet weight and dry weight of carrot
are decreasing. The highest competition between carrot and weed occurred in the treatment of combination between
organic manure which combines with EM. The added EM on organic manure could increase weed competition on
carrot.
