Fig. 3. Grass (closed circles) and legume (open circles) contributions to sward dry matter in May of the postseeding year, 14 mo after frost seeding with six temperate pasture species. Means are over four replicates at each of seven sites. Presence of * or ** indicates significance of linear regressions for grass (G) or legume (L) dry matter on seeding rate, or significance of the difference between linear regression coefficients for grass (ß_G) vs. legume (ß_L) at P = 0.05 or 0.01, respectively
