Irrigation systems must be capable of supplying the needed amount of water at the critical plant water stress periods, which occur in mid-summer for most crops. Wind power alone normally can not supply all of the energy needed for irrigation during these peak water-use periods. However, with a wind-diesel pumping system as described in this paper, sufficient water was supplied and diesel fuel was saved. The wind-diesel system used a diesel engine and a vertical-axis wind turbine operating together to provide power to the pump. When the windspeed was 6 m/s or greater, wind power reduced the load on the diesel engine and saved fuel. The wind turbine, rated at 40 kW, reduced the load on the diesel engine from 47 to 9 kW and reduced fuel consumption by 50 % in windspeeds above 16 m/s. The reduction in fuel consumption was linear between diesel engine loads of 100 and 20 %, but fuel savings never exceeded 50 %. The wind turbine was capable of providing only 81 % as much power as the diesel engine and could not fully unload it. Seasonal irrigation fuel savings, estimated at 13 %, was not as great as it could have been had the turbine better matched the pumping load.
