| Abstract | ||
| This study aim to show the effect of soil contamination with crude oil and its derivatives on the dry weight and Nutrient minerals on flax (Linum usitatissimum L.) and safflower (Carthamus tinctorius L.). This experiment was carried out in plastic pots and under Plastic house conditions, the treatment was carried out with crude oil, used car's engine oil and used generator's engine oil at three concentrations 1-2-3% for each treatment ,in addition to the comparison treatment. The results showed a significant decrease in the dry weight of the shoot systems of flax and safflower when treated with crude oil at a concentration of 3% amounted to 0.043-0.124 g, respectively, and the dry weight of the root systems amounted to 0.022-0.015 g, respectively. There was also a significant decrease in the concentration of calcium in the shoot system of flax and safflower plants when treated with crude oil and used generator oil at a concentration of 3% amounted to (1,900-1.950) mg\g, respectively. The calcium concentration has also decreased in the root system of flax and safflower plants when treated with used generator and car oil at the concentration 3% amounted to 1.500-1.600 mg\g, respectively. Potassium concentration decreased in the shoot and root systems of flax and safflower plants when treated with generator engine oil and crude oil at a concentration of 3% and reached 6.900-10.45 and 4.150-8.800 mg\g, respectively, compared to the control treatment and other treatments | ||
