In recent years, non-conventional planting configurations in corn (Zea mays L.) and peanut (Arachis hypogaea L.) have received renewed interest, thus an evaluation of multiple planting scenarios using current cultivars, cultural practices, and technologies were conducted. Based on the results of studies conducted in 2012–2014 in corn and 2008-2010 and 2014 in peanut, Georgia farmers have greater flexibility in selecting between row spacings and row patterns (76- and 91-cm single-row and 91-cm twin-row) for production without major concern for yield decline or pest increase. In peanut, producers may not observe yield or TSWV reducing benefits from twin-row patterns using high-yielding TSWV-resistant cultivars as they once had with previous cultivars in current TSWV conditions. Based on this research, 91-cm single-row patterns are the most economical for production of corn and peanut in Georgia overall.
