A 3-year study compared rye (Secale cereale L.) grain and ‘Coastal’ bermudagrass (Cynodon dactylon L.) forage yields with cropping systems of Coastal only, rye only (conventional seedbed), and Coastal-rye (rye seeded in Coastal). Five rates of N were added for rye and two rates of N were added for Coastal.

Sod-seeded rye yielded as well as conventionally seeded rye. First-harvest Coastal yields were lower with Coastalrye than with Coastal only. This reduction in Coastal yield increased as the rates of N added for rye increased. Annual Coastal yields, averaged over all rates of N added for rye, were as high with Coastal-rye as with Coastal only for 2 of the 3 years.

Light intensity, soil water, and soil temperature were lower with a high rate of N added for rye than with a low rate. All of these factors probably contributed to the low first-harvest Coastal yield, but shading of Coastal by the rye grain crop is suggested as the dominant factor.
