AbstractSupplemental irrigation generally increased seedling density the seeding year; however, this response was not maintained the year following seeding. Above-average precipitation minimized the importance of irrigation the seeding year. Seeding mixture appeared important with a 6- and 4-species mixture providing better establishment than a 2-species mixture. This was apparently due to the relatively large proportion of switchgrass (Panicum virgatum L.) in the 2-species mixture and its generally poor establishment. The reduced seeding rate resulted in better stand establishment than the recommended rate on a tilled seedbed (1.1 and 0.7 seedlings/0.1 m2, respectively), while neither seeding rate provided an acceptable stand (>0.5 seedlings/0.1 m2) with the no-till treatment in small plot evaluations. Seedbed tillage also resulted in a higher seedling density than no-tillage (1.3 and 0.5 seedlings/0.1 m2, respectively) for the production-level field trial. Seedling density was doubled with depth bands (1.2 vs. 0.6 seedlings/0.1 m2). These results suggested that a tilled seedbed on sandy cropland with adequate moisture results in successful stands. A native, warm-season grass mixture (4 or more species) is recommended with a seeding rate of 15 PLS/0.1 m2 using equipment with depth bands.
