Five cultivars and two experimental lines of alfalfa (Medicago sativa L.) displayed significant differences in the grams of water required to produce a gram of dry matter under controlled environmental conditions. Stem and petiole weight, leaflet weight, total forage dry weight, and leaf area were all significantly associated with the water requirement of alfalfa. Leaf thickness and palisade cell density were not associated with water requirement or total transpired water, but did differ significantly among cultivars.
