Abstract

Oklahoma growers have increased their adoption of strip tillage (strip-till) and no tillage (no-till) systems as a means of reducing production costs and conserving soil resources. An experiment was conducted over three years to study the effects of three tillage systems [(conventional till (CT), no-till (NT), and strip-till (ST)] on pod yield, peanut grade, pest pressure, and economic profitability. Insect, disease, and weed incidence were determined in each year of the study. Peanut yield and grade were determined by mechanically harvesting the plot. No consistent differences were detected between NT and CT in peanut grade or yield when tillage systems were combined across years. In addition, no consistent differences were observed in disease incidence and insect populations. Economic analysis indicated that the NT system saved $93 ha−1 and generated $179 ha−1 more revenue compared to the CT system. Reduced tillage practices, especially NT, seem to be a good fit for SW peanut production areas.
