Comparative yields showed the air-seeder to be equal to or better than other seeders and that "no-till" was equal to spring plowing or field cultivation. In the fall of 1978 winter wheat and winter rye were seeded in wheat stubble with an air-seeder. Winter wheat planted on adjacent fallow suffered 95 % winter kill but that in the stubble had 70 % survival and yielded 35 bushels/acre. In 1979 the air-seeder was compared with a conventional press drill in planting spring wheat and durum in stubble prepared for planting by spring plowing, field cultivator, and no-till. Yields were greatest from plantings made with the press-drill on spring plowed and/or cultivated land. However, on the no-till treatment the air-seeder yields were about 6 bushels/acre greater than from the press drill. Two years of results suggest the air-seeder is capable of appropriate placement of seed under a wide range of crop residue and soil conditions if land surface is relatively smooth and if depth control is effective.
