The research showed that the aqueous extracts of decomposed of root plant and root exudates that (they have escaped to the associated soil of crabgrass) depressive seed germination to 70% and 80% to seedling growth depressive in miotic index and showed high efficiency in cell division in root tip of bladygrass plant. The undecomposed and decomposed treatment of crabgrass containen phenolic, steroid,tanin,coumarin,and essensial terpenes it is found in un decomposed treatments and not found in the decomposed treatments, and glycoside found in undecomposed treatments and not found in decomposed treatments.
