Technical Abstract: Cotton and poultry production, and adoption of no-tillage practices are increasing in the Southeast. We investigated impacts of tillage and nutrient management on cotton (Gossypium hirsutum L.) yield from a Cecil sandy loam (clayey, kaolinitic, thermic Typic Kanhapludults) near Watkinsville, GA. Factorial treatments were: conventional tillage (CT) and no-till (NT); conventional fertilizer (CF) and poultry litter (PL). In two years of experiment, we found the lowest and highest average lint yields to be 0.90 Mg/ha (CT,CF) and 1.32 Mg/ha (NT,PL), respectively. Average lint yield ratios were: NT/CT 1.27, PL/CF 1.18, CTPL/CTCF 1.16, NTCF/CTCF 1.25, NTCF/CTPL 1.08, NTPL/NTCF 1.20, NTPL/CTPL 1.29 and NTPL/CTCF 1.49. Although most cotton in the Southeast is still produced with conventional tillage and chemical fertilizer, production could be improved with NT and PL management.
