In an effort to remain profitable, many cash grain farmers have shortened rotations or have changed cropping systems to include more frequent planting of high-value but nutrient demanding and pest-vulnerable crops. This increase in cropping intensity has led to yield declines, compacted and poor quality soil, and increased pest problems. Cover crops in the Brassica (mustard) family offer benefits in soil conservation, improvement in soil quality, and suppression of certain pests and soil borne fungal diseases. The objective of this work was to compare stand establishment and biomass yield of Oilseed Radish and Oriental Mustard established with conventional no-till drilling, and a new process whereby aeration tillage, manure application and cover crop seeding were done in a single, efficient operation. Based on the results in 2004, the biomass yield of Oilseed Radish and Oriental Mustard established as a late summer seeding in untilled wheat stubble with the experimental process was equal to or better than conventional no-till seeding.
