Pollution from oil spills affects the soil and crops, so this study evaluated the effect of soil contaminated with diesel at different concentrations on the development of Creole corn (Zea mays).Creole corn seeds were placed in soil contaminated with diesel at different concentrations: 0%, 0.5%, 1%, 2%, 4% and 8%, each treatment had four replicates, the experimental units were kept under controlled laboratory conditions.Variables such as germination percentage, plant height, leaf area, mortality rate, aerial and root biomass were evaluated at 7, 10, 14, 21 and 28 days after sowing.The results indicate that germination was delayed and a delay in the appearance of the sprout was also observed at higher concentrations.Plant height, root area, biomass, and taproot were affected at higher concentrations (p < 0.05).Presence of chlorosis and malformations in the leaves were observed on the ninth day after planting, causing the onset of wilting of the leaves in the 4% and 8% treatments.Exposure to diesel significantly reduces the growth of native corn in its early stages of development.
