Tillplanting units were tested in the field at three speeds and three depths. Crop emergence data were collected on the 7, 14, and 20th days following seeding. Results indicated that the highest values of seedling emergence were obtained with unit two, which was equipped with a Barton angle disc opener, at 3 or 5 km/h speed, and 125 mm depth of operation for pea or corn crops.enAttribution-NonCommercial-NoDerivs 2.5 CanadaPresentation
