Field studies were conducted between 1997 and 2000 at Epemakinde, Ondo State, Nigeria to evaluate the influence of plant residue management on the physical and chemical properties of soil and the nutrient contents of plantain leaves. The residue management consists of insitu application of organic materials (mulching), parking and burning of trash/residue. The experiment was a randomized complete block design. Thirty six core soil samples were collected from different plots under the different residue management systems before and after the experiment with soil auger. The results showed nitrogen content of the soil was low while the soil organic matter (SOM), phosphorus (P), potassium (K), and Calcium (Ca) increased after two years of cropping irrespective of residue management practices. The nitrogen level in the leaf lamina obtained in this work varied between 2.36% to 2.39% which fell below the critical nitrogen level (2.60%) and hence confirmed the result of the soil analysis indicating that the soil nitrogen (N) was slightly lower or inadequate for plantain. The potassium (K), magnesium (Mg), Calcium (Ca), Manganese (Mn) and iron (Fe), copper (Cu) and Zinc (Zn) contents of the third leaf obtained in the investigation were found to be adequate.
