Studies have shown that sod-based cropping systems can improve soil quality and field crop productivity in the southeastern USA.  An experiment was conducted at University of Florida, the North Florida Research and Education Center, Quincy, FL to determine corn (Zea mays L. cv. Dekalb 69-72 RR2) growth, physiological, and silage yield responses to different sod-based crop rotation systems. Three rotation systems were: (1) bahiagrass-bahiagrass-cotton-corn (B-B-C-M); (2) bahiagrass-bahiagrass-peanut-corn (B-B-P-M); and (3) bahiagrass-bahiagrass-corn-corn (B-B-M-M). The experimental plots were established in 2001 with a randomized complete block deign and four replications. Corn plant height, the number of nodes, leaf chlorophyll, and LAI were measured in the 2007 growing season. Soil N, P, K, and water contents as well as soil organic matter (OM) were determined. Finally, silage yield and quality were determined. Corn following bahiagrass in the B-B-M-M had a 27% greater LAI and 16% higher leaf chlorophyll than the corn plants following either cotton in the B-B-C-M or peanuts in the B-B-P-M during growth, resulting in a higher silage yield. Soil N, P, and K contents at the planting time did not differ among the three cropping systems, but soil OM and soil water content of the first-year corn plots in the B-B-M-M system were consistently higher than the corn plots in the B-B-C-P and B-B-P-M systems. Therefore, enhanced soil OM and improved soil water content may be major contributors of bahiagrass to improvement of corn growth and silage yield in the sod-based cropping systems.
