Technical Abstract: Water is the limiting factor in Great Plains agriculture and sustained viability depends on efficient capture and utilization of scarce precipitation. We will examine the efforts to increase precipitation capture and storage during the non-growing season (fallow) as well as water utilization by crops in various cropping systems. The main objective is to review published research reports of current dryland agriculture practices from the southern and central Great Plains as it pertains to precipitation capture and utilization. Most publications report on fallow efficiency and/or crop water use efficiency (WUE). However, there is limited information available on precipitation use efficiency (PUE) for the entire cropping system. We will report on recent and current progress on improving management of limited water in dryland cropping systems.
