Title: Frequency and Rate of Irrigation as Factors in Forage Growth and Water Absorption<sup>1</sup>
Abstract: Synopsis Alfalfa irrigated with 3 inches of water whenever available soil moisture to an 18‐inch depth was 60, 40, 20, or 0% produced relative yields of 100, 81, 63, and 37%. Moisture absorption was greatest in upper 6 inches of soil and decreased when available soil moisture dropped to 25 to 30%. Below 15% available soil moisture, plants showed moisture stress and rate of stem elongation dropped almost to nil. Similar water efficiency in production of top growth, decreased production, and rate of stem elongation as soil approached the permanent wilting point indicates that water is not equally available between field capacity and permanent wilting point.
