Most peanut (Arahcis hypogeae L.) production occurs under conventional tillage. Reducing tillage trips can reduce production costs. Growers switching to strip-tillage peanut can experience a decrease in yield on certain soil types. This study compared strip-till utilizing fall prepared raised beds and rip and beds to standard flat strip-till on a sandy soil at Tifton, GA and a clay soil at Plains, GA. At Plains, the rip and bed and raised bed reduced digging losses by 62 and 47 %, respectively. Soil compaction decreased by 3.3 and 4.7 times for the raised bed and rip and bed, respectively. The rip and bed increased yield by 465 kg/ha over flat bed. At Tifton, no differences in yield or digging losses were found. Soil compaction decreased by only 1.9 and 2.5 times for raised bed and rip and bed, respectively. Results suggest bedding can minimize yield loss on finer textured soils.
