The study aimed to assess the impact of irrigation with water contaminated by oil waste on certain growth traits of two field plant species, namely pea (Pisum sativum) and broad bean (Vicia faba). The traits examined included germination rate, plant height, leaf count, and number of lateral branches.
Seeds were planted in plastic pots under suitable growing conditions, including temperature and light, and were irrigated with water contaminated by petroleum derivatives. A pot of each species was also planted for comparison and irrigated with clean water under the same conditions to highlight differences in plant growth.
The results indicated a slight negative effect on pea plants, as irrigation with contaminated water reduced plant height to an average of approximately 24.1 cm. However, the number of leaves increased to an average of 211 leaves, despite the smaller size of the leaves compared to those of the control plants. The number of lateral branches in pea plants decreased, averaging 24.1 branches, and flowering and fruiting occurred in limited quantities.
In contrast, broad bean plants were significantly affected by the contaminated water, failing to withstand the polluted conditions, with a maximum average height of only 12 cm. The plants began to reduce leaf size and exhibited wilting and mortality by the 50th day of germination.
