Abstract: In averting the menace of the adverse effects caused by the application of inorganic fertilizer to agricultural crops, there is the need to adopt the use of organic yield enhancers. One of such is the use of Moringa oleifera leaves, known to be in abundant supply especially in the South west, Nigeria. This study was conducted in the screen house of the Department of Sustainable Forest Management (SFM), Forestry Research Institute of Nigeria (FRIN), Jericho, Ibadan, located on the latitude 07023N and longitude 03051E. The objective was to evaluate the potential of Moringa leaf extract (MLE) and frequency of application on increased maize productivity.
