Fig. 2. Yield of fresh green forage from 93 grass–legume mixtures grown in three different experiments under irrigation at Logan, UT, during 1944 to 1951. The soil type was a Millville silt loam (Coarse-silty, carbonatic, mesic Typic Haploxerolls). Manure and P fertilizer had been applied to maintain high soil fertility. Plots were grazed three or four times per year with milking cows and yields measured before grazing. Data points are averages of 6 yr in Experiment A, 4 yr in Experiment B, and 5 yr in Experiment D. Adapted from Tables 5, 8, and 11 from Bateman and Keller (1956).
