Technical Abstract: Currently, most Valencia peanuts are grown in single rows on 36 to 40 inch beds. Because Valencia peanut plants have an erect growth habit, they do not spread over the whole bed like runner market type peanuts. This allows the possibility that multiple row planting arrangements could improve canopy coverage and row closure with Valencia market type peanuts. The purpose of this study was to identify which of three different planting patterns provided the most agronomic benefit in Valencia peanut and determine an optimum plant population for the diamond pattern. In 2008, a new set of experiments with the variety ‘Georgia Valencia’ was initiated. This experiment included single row, twin row, and the diamond planting pattern at the same target populations of 6 seed per linear foot of row. In 2008, the plants had less response to planting patterns when compared to the responses observed in 2006 and 2007. Yield potential has consistently been higher near Brownfield, TX compared to other locations in Texas and New Mexico for ‘Valencia C’, however the best yield with ‘Georgia Valencia’ was achieved near Farwell in the single row planting pattern. In Farwell, ‘Valencia C’ planted in a diamond pattern at 60% of the single row population produced an average of 25-30% more leaf area per plant compared to all other planting patterns. Variety ‘Georgia Valencia’ planted in single rows grew 2 and 4 inches taller in Farwell and Brownfield, respectively when compared to twin row and diamond configurations. Yield for ‘Valencia C’ was much lower in 2008 compared to 2006 and 2007 at both locations. In Farwell, ‘Georgia Valencia’ planted in single rows produced 2,300 lb/A which was 35% greater than the yield produced by comparative twin row and diamond planting patterns. It was noted that ‘Georgia Valencia’ was 10 to 14 days less mature than ‘Valencia C’.
