Interpretive Summary:

Technical Abstract: Maintaining surface residue combined with higher production costs have renewed interest in conservation tillage systems for peanut (Arachis hypogaea L.) production. Our study was designed to compare surface residue cover, yields, and sound mature kernels (SMK) following two strip tillage systems (narrow vs wide) with three peanut cultivars (Anorden, AP-3, and GA 02-C) across each strip tillage system with two row spacings (single vs twin), and evaluate soil moisture between these treatments. Two sites were established on a Malbis fine sandy loam (Fine-loamy, siliceous, subactive, thermic Plinthic Paleudults) in Fairhope, AL and a Dothan loamy sand (Fine-loamy, kaolinitic, thermic Plinthic, Kandiudults) in Headland, AL during the 2004 growing season. Preliminary results indicated that surface residue cover was higher following the narrow strip tillage system at the Fairhope location. Peanut cultivars exhibited the only yield difference, initially, at Fairhope, while no yield differences were observed at Headland. GA 02-C and AP-3 tended to yield higher than Anorden at both locations. GA 02-C produced higher SMK at both locations. Neither strip tillage system or row pattern had any effect on yield or SMK at either location. Although not significant, soil moisture contents measured at Headland corresponded to observed peanut yields, while row spacing had no effect on soil moisture contents. Preliminary results indicated that peanut conservation tillage practices may not require a wide tillage strip regardless of row pattern.
