The trial from which these results were obtained was sown in February 1930. Plots of eighteen kinds of grasses and clovers were sown in triplicate, each plot being 11 yards by 18 inches. The plots were cut with a lawn mower at different periods when the growth was 1½" - 3” high. Air dry weights were secured. It will be noticed from the graph that nine cuts were taken in the first year, four cuts in the second year, and three cuts in the third year. In only two instances, in the spring of the first season, was the interval between successive cuttings less that one month. The plots were not grazed except for one short period when a mob of sheep was put on for twenty-four hours to get some information on the palatability of the different species. Superphosphate at the rate of l½ cwt. per acre was applied in the winters of 1931 and 1932.
