Yield and quality of forages grown on mine spoil
Pasture or hayland is a potential use for much of the reclaimed mined land in Kentucky. To determine the usefulness of several species for forage production, two study areas were established, one in the eastern coal fields, the second in the western coal fields. Eight species were seeded in eight different mixtures at each location. Each plot was harvested twice each year to determine yield, and samples were analyzed to determine percent protein, DMD, and sugar. Analysis of variance of the data show that there are significant differences in yield, stand, percent protein and percent DMD among the different species. There is also a significant difference in the yield of the same species between the two study areas. In eastern Kentucky, two mixtures, switchgrass-Interstate sericea lespedeza and Caucasian bluestem-Appalow sericea lespedeza yielded more hay than tall fescue-Interstate sericea, the standard of comparison. In western Kentucky, all seeding mixtures yielded more than the tall fescue Interstate mixture. There is no difference in stand among the species in eastern Kentucky. In western Kentucky, Caucasian bluestem, tall fescue, and switchgrass have better stands than other species.
