Abstract
Alfalfa production is basically a linear function of plant transpiration and stomatal conductance that drives carbon dioxide uptake to build plant carbohydrates and biomass. Cutting schedules, irrigation non-uniformity and poor scheduling can result in lost yield and water use efficiency. Improved uniformity and scheduling of pivot and subsurface drip irrigation (SDI) can result in significant yield and water use efficiency (tons hay/inch of water) increases, but the additional capital and operational costs of these systems can equal as much as 2 to 3 tons per acre additional yield over the cost of border strip/flood irrigation.
