Cover Story: Irrigation management practices that reduce water use with acceptable impacts on yield are important strategies to cope with diminished water supplies and generate new sources of water. This study was intended to assess the effects of moderate water deficits, to maintain robust alfalfa yields, while conserving on-farm water. Data collection and analysis were conducted at four commercial fields over an 18-month period in the Palo Verde Valley, California. A range of summer deficit irrigation strategies was evaluated including 12.5–33% less irrigation water than farmers’ normal irrigation practices. The findings indicate that the proposed deficit irrigation strategies could provide a reliable amount of water and sustain the economic viability of alfalfa production, while data from multiple irrigation seasons are required to fully certify this conclusion.
