Technical Abstract: Most Valencia peanuts are grown in single rows on 36 to 40 inch beds. Because of their bunch-type and erect growth habit, Valencia peanuts do not spread over the whole bed and have the opportunity to benefit from multiple row planting arrangements. This study was conducted at locations near Portales, NM and Brownfield, TX to compare single row, twin row, and diamond planting patterns in Valencia peanut on 36 inch beds. The diamond pattern is established by planting 4 rows on a bed and placing seed equidistant from each other to optimize individual plant growing space. Planting populations for single and twin row patterns were based on sowing 6 seed per linear foot of row (~87,000 seed per acre) to establish comparative populations to current single row planting methods. This study included six planting treatments, including single row, twin row, and four diamond planting patterns. The diamond planting patterns included populations to represent, 60%, 80%, 100%, and 133% of 87,000 plants per acre. At mid-season, each plot was sampled by pulling all plants in a 0.5 meter by 3 foot area for biomass partitioning. This was done to document mid-season plant productivity and growth stage on an area basis to compare the five planting arrangements. Two weeks prior to harvest, another sample was pulled from the plots for pod blasting to estimate maturity differences between planting treatments. The two research locations had different yield potential. At mid-season, plants in the diamond 133% planting populations had significantly lower leaf area per plant than some of the lower seeding rates at Brownfield. Plants in lower populations initiated more total fruit at mid-season compared to plants in higher populations at both locations. At harvest, plants in lower populations tended to have more pegs and pods per plant than plants in higher populations at both locations. Yield near Portales ranged between 2480 and 3530 lb/A and the range of yield near Brownfield was between 3150 and 4720 lb/A. Diamond and twin row planting patterns with high populations produced significantly greater yield compared to single row planted peanuts near Portales. Peanut grade was consistent among planting pattern treatments ranging between 68 and 72 for both locations.
