In the more humid regions of the prairies, increased use of intensive cropping systems with less summerfallow has shown the need for evaluating methods of seeding cereal crops on stubble land. An acceptable method of seeding should protect the soil, conserve moisture, provide weed control and effect good seed placement. The importance of maintaining a trash cover to prevent soil erosion has long been recognized. However, this often interferes with the placement of seed into firm moist soil and frequently farmers plow or burn their fields to remove this obstacle. The conservation of soil moisture in the spring is also necessary to ensure adequate germination and emergence of the crop. Weeds, a major problem on most farm fields, use moisture unless removed by tillage or herbicide applications. In the drier regions of the brown and dark-brown soil zones the discerseeder gave good yields of wheat and control of weeds. In Alberta, Ander son and Smith (1) found the discerseeder was satisfactory when the trash cover varied from 1,500 to 4,000 lb/A (representing residues from wheat crops varying from 15 to 40 bu/A). Also, at Swift Current (5, 7), good results were obtained with the discerseeder when the importance of correct adjustment for depth of seeding was emphasized. There was no ad vantage in using disc and hoe drills which required an additional cultural treatment before seeding. Yields with the wide-blade cultivator-seeder were lower than those from other methods (1).
