Potential of Drip Irrigation in Row Crops for Agriculture Water Conservation in California

摘要

Results are presented of a two year study comparing the evapotranspiration (ET), yields and the microclimate under drip and furrow irrigated processing tomatoes. Results from a water conservation standpoint were not encouraging with approximately equal values of evapotranspiration found for the two methods of irrigation. This was true in replicated field pilot studies as well as the lysimeter studies. The latter studies indicate that ET under furrow irrigation was considerably higher than under drip irrigation.
