Remediation technology is a promising technique decrease pollutant like hydrocarbons from the environment. An experimental work was made at green house of University of Technology in order to study the effect of crude oil on the vegetate growth and to measure the decrement which happened on shoot height, germination rate and the reduction of total petroleum hydrocarbon (TPH), which result, by this phytoremediation technique. The samples of soil were measured for TPH reduction and removal by Horiba model (oil content analyzer) OCMA–350. Five doses were used in this experiment (0 control, 10x103, 30 x103, 50 x103, 75 x103) (mg crude oil / kg soil). The polluted soil used in this study appeared to be a harmful environment for alfalfa plants, leading to serious adverse effects on alfalfa germination and growth. Seed germination is known to be a sensitive process affected by environmental factors like the presence of soil pollutants.
