Interpretive Summary: Large amounts of cover crop residue can create problems with any tillage practice that must be conducted in the spring, prior to planting operations. Thus, crops must be managed appropriately to prevent planting problems. The most common problem is “hair-pinning”, where residue is pushed into the soil rather than being cleanly sheared. Hair-pinning creates a condition where the seeds are unable to have good seed-soil contact. Another major problem is accumulation of cover crop residue on planting units, which causes frequent stops to clean the equipment. In this study we determined the effect of different cover crop rolling directions (relative to the planting rows) and different commercially available row-cleaner attachments on cotton emergence and yield at two location in Alabama. Based on preliminary results in 2004, the greatest cotton plant emergence and the highest yield were found with parallel rolling pattern and Yetter row cleaner at E.V. Smith and TVS. The worst results came with the perpendicular and 45 degree rolling patterns, and no–row cleaner, also at these two locations.
