339 Water Conservation in Irrigated Cropping Systems

Oral Session
S06 Soil & Water Management & Conservation
The objective of this is to address key elements in the soil, plant, water relationship for conservation of water in irrigated cropping systems. One emphasis will be limited irrigation cropping systems for enhancing water use efficiency and water conservation. Other topic areas are water production functions, irrigation management, and the environmental and economic considerations of deficit irrigation.
