Abstract
An irrigated monoculture corn and soybean-corn cropping systems study with cropping system as the first split, corn hybrid as the second split, and N fertilizer rate as the final split in four replications was used. Four commercially available Pioneer brand corn hybrids (3162, 3379, 3394, and 3417) were evaluated in both cropping systems. Nitrogen fertilizer as ammonium nitrate was broadcast at rates of 0, 45, 90, 135, and 180 lb N/acre in 1991 and 1992 and 0, 56, 112, 168, and 224 lb N/acre in the 1993 and 1994 growing seasons.
