Item Open Access Protein and chlorophyll contents of solanum melongena on diesel oil polluted soil amended with nutrient supplements(Maxwell Scientific Organization, 2011-09-10) Akujobi, C. O.; Onyeagba, R. A.; Nwaugo, V. O.; Odu, N. N.The study investigated the remediation effect of nutrient amendments of diesel oil polluted soil on protein and chlorophyll contents of eggplant (Solanum melongena). Soil samples were polluted and amended separately with different weights of poultry waste, pig waste, cow dung and inorganic fertilizer. Soil samples were also polluted with diesel oil without amendment to achieve 2, 4, 6, 8 and 10% pollution. Samples were analyzed at two weeks interval for sixteen weeks. The plant protein and chlorophyll were affected adversely by the diesel oil pollution and the higher the level of pollution, the more the effect. The nutrient amendments were able to remedy the effect of the diesel oil pollution. The remediation effect was nutrient weight dependent and the best remediation effect was observed in poultry waste amended samples. This study has shown that diesel oil contaminated soil may have adverse effect on the protein and chlorophyll contents of plants, but this can be remedied by addition of organic nutrient supplements especially poultry waste.
