Abstract

Numerous variations of conservation tillage (CT) systems have been
adopted for soybean, corn and double-crop wheat grown on Coastal
Plain Ultisols. A systematic investigation of the effect of these variations
in cultural practices on yields was needed. A long term tillage study was
established in Florence, SC to study these variations in conservation
tillage systems. Soybean yields were favored by CT but were reduced by
drilling. Burning of double-crop residues showed no yield advantage.
Corn yields were slightly reduced by conservation tillage systems in
which residues were left standing at planting. Double-crop yields were
greatly increased by deep primary tillage. Double-cropped wheat and
reduced operations with CT in soybean increased cash returns. However,
caution is still in order when considering CT for corn in the Coastal
Plain.
