Unadjusted (A, B, and C) and adjusted (D, E, and F) CI values for June through December 2004 and May 2005 for the North Appalachian Experimental Watersheds (NAEW), Western Agricultural Experiment Station (WAES), and Northwestern Agricultural Experiment Station (NWAES) in Ohio. The T0, T25, T50, T75, T100, and T200 are the six rates of corn stover at 0, 25, 50, 75, 100, and 200%, respectively. The error bars represent the LSD values by month.
