Agricultural Engineering is the application of engineering and biological principles to develop technologies and solutions to problems in agriculture to remove drudgery, and to increase productivity and efficiency of farmers. The Department of Agricultural Engineering is currently organised into four sections including Agricultural Machinery Engineering, Soil and Water Engineering, Food and Postharvest Engineering and Agro- Environmental Engineering.

The Department has the following Research Groupings

Agricultural Machinery Engineering Research Group
Agricultural Engineers working in this group apply mechanical engineering principles in the design, fabrication and operation of all types of agricultural machinery during research. At the farm operational level, it employs the use of agricultural machinery for the full spectrum of land preparation, seeding, fertilizer application, spraying of agrochemicals for soil and crop protection and harvesting, thus reducing the drudgery in agricultural work.

Agro-environmental Engineering Research Group
The Agro-environmental Engineering involves the use of engineering principles to deal with biological materials in the management of the agro-environment. Topical issues as bioenergy and agricultural waste management have become important. The use of thermodynamic principles in the control of plant and animal environments have become a preoccupation in agricultural systems where the issues of the appropriate design of farm structures to provide suitable environmental conditions for the storage of agricultural materials are considered.

Food and Postharvest Engineering Research Group
Food and Postharvest Engineering involves applying engineering principles to handling crop, livestock and fish products, which are essentially biological materials. It is quite clear that the traditional agricultural engineering, which dealt largely with agricultural machinery, has expanded to handle biological materials. The post-harvest handling of crops, including processing and preservation processes are mechanised, with the primary objective of extending the shelf life and reducing post-harvest losses of agricultural materials.

Soil and Water Engineering Research Group
Soil and Water Engineering involves the application of engineering principles to soil and water management in agriculture resulted in drawing subject matter from civil engineering to apply to issues of irrigation, agricultural land drainage and reclamation and soil conservation. This is known as Soil and Water Engineering.
