Increased interest in winter canola (Brassica napus L.) production throughout the Southern Great Plains has brought fourth several issues regarding production management. Recently, producers have observed poor stand establishment when seeding canola into a no-till environment. The objectives of this study were to determine if type and amount of residue affects canola stand establishment in a no-till system, determine if differences exist in seed opener design to successfully seed canola in a no-till environment, and identify the optimal planting depth for winter canola in Oklahoma . Treatments will include four different seed opener designs, seeding into three different residues: wheat (Triticum aestivium L.), grain sorghum (Sorghum bicolor (L.) Moench), and soybean (Glycine max (L.) Merrill) at two planting depths (1.2 and 3.8 cm). A control treatment will consist of seeding into a conventionally tilled seed bed. Data will be collected on emergence, crown height, plant height/seed canopy height, lodge percent, and yield.
