Technical Abstract: Interstate litigation regarding water rights has focused much attention on agricultural water use in the Southeast. Moratoria on agricultural withdrawal permits in certain watersheds and voluntary auctioning of agricultural water rights have occurred, thus the future expansion of irrigated acreage may be limited unless alternative methods of irrigation are adopted or current practices are made more efficient. The interaction between reduced irrigation capacity and tillage, including the possible conservation of water with reduced tillage systems, is of vital interest to peanut growers. A factorial arrangement of three tillage systems (conventional, wide-strip, and narrow-strip) and four supplemental irrigation levels (100%, 66%, 33%, and 0% of a recommended amount, based on Irrigator Pro®) with three replications is being monitored for yield and overall economic viability in a corn-peanut-cotton rotation.
