The study was carried out with the objectives evaluating the technical performance of the pumps used in smallholder irrigated agriculture, studying the energy uses during pumping and identifying the possible causes of inefficient energy use, and evaluating the costs of pumping used during irrigation. A study to identify the occurrence of pumped irrigation systems in Thika and Yatta District, Kenya was done. The results imply that without proper selection of the irrigation equipment, poor designs as well as lack of operational and management skills, the farming enterprises can be rendered uneconomical. This calls for embracing of the engineering, agronomic as well as management techniques at the farm level to ensure sustainability of irrigated agriculture as well as enhance its economic viability.
