Three ryegrass variety trials were conducted in Alabama during the winter of 1980-81. Ryegrass entries were planted at 20 pounds per acre in rows 6 inches apart, using plots 4 x 20 feet with four replicates. The
tests were planted October 2 at the Plant Breeding Unit, October 8 at the Sand Mountain Substation, and November 3 at the Gulf Coast Substation. The late planting dates were a result of dry, hot weather in September which continued through October in southern Alabama. Tests were fertilized at planting with 50 pounds nitrogen per acre and adequate rates of phosphorus and potassium. After each harvest, 50 pounds nitrogen per acre were applied. Plots were clipped with a flail-type harvester wherever sufficient forage was
available. A sample of green forage from each plot at each harvest was oven dried for determination of dry matter.
