Okunade David Adebimpe Profile



Dept of Agricultural and Biosystems Engineering


Dr. David A. Okunade is a Senior Lecturer with the Department of Agricultural Engineering, Obafemi Awolowo University, Ile-Ife but currently a Faculty on Sabbatical Leave with the Dept. of Agric. and Biosystems Engineering, Landmark University, Omu-Aran Kwara State. His primary research interest is in modelling crop yield and water-use under rainfed and rainwater harvesting conditions with research focus on crop yield, machinery traffic and soil compaction, and organic matter effect on properties of some Nigerian soils. Some other works include pond water and sewage effluent treatment, and wastewater irrigation and the effect of cassava wastewater on agricultural soils and nearby water resources in the processing environment. He has many academic publications to his credit and has attended many conferences locally and internationally. He is a Registered Engineer with COREN since 2002 and Members of both the Nigerian Institution of Agric. Engineers and the Nigerian Society of Engineers. He is happily maried with children.
