Abstract
Three prototypes of a single till-planting unit system suitable for Egyptian agriculture
were evaluated in clay soil by determining seedling emergence with three crops. 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.
