Abstract
ABSTRACT Objective This experiment was designed to determine the effect of wheat establishment method [conventional clean tillage (CT) vs. no-till (NT)] and planting date on forage and animal production over 3 yr. Materials and Methods No-till pastures (each 1.6 ha) were planted on 3 planting dates: early, August 15 (n = 8, ER); mid, September 1 (n = 8, MD); and late, September 15 (n = 8, LT). Clean-till pastures (each 1.6 ha) were established on MD (n = 3) and LT (n = 3) planting dates. Steers (n = 360, BW = 249 ± 24.7 kg) were placed on wheat pasture for the fall and winter grazing season and replaced with a new set of steers (n = 720, BW = 280 ± 44.9 kg) for spring grazing. Results and Discussion Although CT MD had the greatest (P ≤ 0.04) forage mass in November, ADG did not differ (P = 0.81) in the fall. Spring ADG of CT MD was least (P Implications and Applications Planting NT ER did not result in improved forage or animal production versus CT MD or NT MD. Clean tillage had advantages over NT if planting is delayed until mid-September, but performance in spring and total productivity were better for NT.
