Rhode Island colonial bent grown for seed was fertilized with various proportions of nitrogen, phosphoric acid, and potash. The ratios included in the test varied in the amounts of each fertilizer element applied. The yield of seed produced was influenced chiefly by the amount of nitrogen applied. Phosphorus and potash had little effect. There was an indication that with high applications of the minerals without a corresponding application of nitrogen the yield were depressed. There was some difficulty with lodging with the highest application of nitrogen. There was little difference in time of maturity between plats receiving different fertilizer ratios. The weight per bushel of seed produced did not vary to any appreciable extent between the various treatments. Liming had only a small tendency to increase the seed yields.
