Estimating Alfalfa Yield: 0.20 to 0.25 tons of alfalfa production for each inch of water use. Estimate the water use based on location, experience, and weather. Assume approximately 1/4″ of water use per day under hot/dry conditions. This means 3.5 – 4.0 inches every two weeks in mid-summer. This means that the crop is producing 0.8 to 1.0 tons of dry matter every two weeks in mid-summer.
