A test to determine whether rye can be grown for cover crop and whether grass can be established in growing rye. View from the southeast corner of Field No. 7 — 3.1 acres. Rye seeded on 9-25-67. Fertilized 250 pounds of 10-20-10 fertilizer at planting time. Top dressed 250 pounds 33-0-0 February 1968.
