Crude oil affecting growth of plants (castor: Ricinus communis, and bean: Vicia faba) and some soil properties

Crude oil is extracted from the ground and has many benefits, but it has other side that make it a pollutant to environment, as it needs a long time to decompose in the water as well as the soil, and if it spills over the soil surface it can cause harm to different plants in varying degrees; it also affects the properties of soil and levels of elements in. The current study examined the effect of crude oil on some soil properties, as well as the growth of studied plants, namely castor and beans (Ricinus communis, Vicia faba). Results after crude oil show increased in all measured samples of beans soil Cho, Hum, K, P, N, EC, pH (44.3, 44.3, 4.6, 10.3, 2.8, 5, 7.6) continuously. The bean plant showed decreased in the results of Length, Dry W, K, P, N, Cho, Chl as (20, 9.2, 8, 6.4, 1.7, 10.8, 11.6). while the castor was Resistant to pollution which were recorded (26, 9.2, 8.5, 4.3, 1.8, 10.3, 12.4) for Length, Dry W, K, P, N, Cho, Chl; the castor soil Not affected by crude oil.
