Synopsis Yields of orchardgrass were increased significantly by NH 4 NO 3 and NH 3 in 1956 in southern Iowa. First cutting yields from NH 3 were reduced because of applicator tillage effects under drouth conditions. Nitrogen carryover was significant. Plots first cut on May 10, 1957, produced lower yields than those cut for the first time on May 1, 20, or 30. Plots cut first time on May 30 yielded highest; nitrogen content was highest on those cut first May 1.
