Background: Zea mays L. is one of the important economic and stable food crops cultivated in the Niger Delta region of Nigeria, where crude oil pollution occurs. The pollution of agricultural lands in this region becomes a major concern to the inhabitants. Objectives: This study was designed to evaluate the pH, and mineral nutrients contents of the experimental soils as well as examine the growth response of Zea mays in mycoremediated crude oil polluted soil using Lentinus squarrosulus. Methods: Fresh cultures of Lentinus squarrosulus were cultured on potato dextrose agar. A basal medium of sawdust in bottle was inoculated with four 0.5mm mycelial disc of the mushroom species under aseptic condition. Crude oil contamination levels of 5, 10, 15, 20, 25 and 30mls were used. The experimental set up consisted of control, pollution, and bioremediation treatments. Viable seeds of Zea mays were sown based on treatment, and plant growth parameters were examined. The physico-chemical parameters of crude oil polluted and unpolluted soils were determined before and after harvest using standard methods. Results: The contents of calcium, sodium, magnesium, nitrogen, phosphorus and potassium increased (P < 0.05) with increase in the concentration of crude oil in soil remediated with Lentinus squarrosulus, while the contents of nitrogen and phosphorus decreased with increase in the concentration of crude oil in pollution treatment. At harvest, the pH values of experimental soil in the crude oil pollution treatment were lower than those recorded before harvest, while the pH values of treatments with L. squarrosulus were higher during harvest than those recorded before harvest. The plant height, stem diameter, leaf number, moisture content and grain yield of the crop in bioremediation treatment with L squarrosulus were higher than those of pollution treatment at all levels of concentration of crude oil, but lower than those of the control treatment. Conclusions: The L. squarrosulus remediated soil improved the mineral nutrient contents and pH values of crude oil polluted soil as well as enhanced the growth performance of Zea mays. This study suggests that L. squarrosulus can be used in remediating the adverse effect of crude oil contaminated sites.
