Abstract
Research was conducted at two locations in North Carolina from 2000 to 2002 to compare yields of peanut, cotton, and corn grown in various rotation sequences in conventional and strip tillage production systems. Peanut yield was similar when comparing conventional and reduced tillage systems within similar rotation sequences at one location on a Norfolk loamy sand soil. At a second location on a Goldsboro sandy loam soil, peanut yield in a short rotation with cotton was lower when peanut was strip tilled into stubble from the previous crop compared with yield in conventional tillage. When a longer rotation between cotton and peanut was established, peanut yield was similar between the two tillage systems. In both trials during the final year of the study, peanut yield was similar between strip tillage in stale seedbeds (beds established during the early spring prior to planting) and conventional tillage. At one location, peanut yield from both of these tillage systems exceeded that of strip tillage into stubble from the previous crop. It is suspected that peanut pod loss during the digging and inverting operation was greater when peanut was strip tilled into crop stubble than when strip tilled into stale seedbeds. The experiment is being continued for an additional cycle to compare long-term response to tillage and rotation. INTRODUCTION Peanut (Arachis hypogaea L.) in North Carolina is typically grown in conventionally tilled systems (Jordan, 2003). Peanut response to reduced tillage has been inconsistent, and on average was reported to be 5% lower than yields in conventional tillage in studies conducted in North Carolina from 1997 through 2001 (Jordan et al., 2002). Although yields were similar in many of the trials, when major differences in yield were noted they often occurred on finer-textured soils and favored conventional tillage. Many of these trials were conducted in short-term or transition (from conventional to reduced tillage) circumstances. It is suspected that response to reduced tillage would be more favorable if peanut and rotation crops are grown in reduced tillage cropping systems for multiple years. Therefore, experiments were established in North Carolina to compare pod yield of peanut and rotation crops grown in conventional tillage and strip tillage systems in various rotation
