Technical Abstract: Tillage options for winter wheat (Triticum aestivum L.) production on the sandy Coastal Plain were evaluated in 1994 and 1995. Treatments examined were surface residue management (double disked and no surface tillage) and deep tillage (paratilled and no deep tillage). Plant populations were lower in the no surface tillage (NT) plots than in the disked (DT) plots. When combined with deep tillage, the NT wheat produced more heads per plant than the DT wheat. Deep tillage increased plant dry weight, kernel number per unit area, and grain yield more for the NT wheat than for the DT wheat. When deep tilled, yields of the NT and DT wheat were similar in 1994 but were 25% higher for the NT wheat in the drier year of 1995. These results indicate there may be no need to incorporate surface residues if the proper equipment is used to plant winter wheat on the southeastern Coastal Plain. Benefits from deep tillage appear to be greater for NT wheat than for DT wheat.
