Interpretive Summary: Peanut production in Oklahoma is generally located in 3 geographical regions across the state: southwestern, west central, and far west. Each region differs from the others in environmental and biological stressors that affect crop production, so the same peanut cultivar will likely perform differently in each growing region. Therefore, the Oklahoma Peanut Variety Trials are conducted in each region annually and are designed to test the performance of commonly grown cultivars and potential cultivar releases against each other. The 2022 growing season was unusually hot with temperatures above 100 ' F for much of July without any rainfall or relief. Consequently much of the peanut crop in the state arrested in development, resulting in an obvious split crop and delayed maturing. Results of these annual trials can serve as a guide for producers when choosing a cultivar to plant. USDA is an equal opportunity provider and employer.

Technical Abstract: Peanut production in Oklahoma is generally located in 3 geographical regions across the state: southwestern, west central, and far west. Each region differs from the others in environmental and biological stressors that affect crop production, so the same peanut cultivar will likely perform differently in each growing region. Therefore, the Oklahoma Peanut Variety Trials are conducted in each region annually and are designed to test the performance of commonly grown cultivars and potential cultivar releases against each other. The 2022 growing season was unusually hot with temperatures above 100 ' F for much of July without any rainfall or relief. Consequently much of the peanut crop in the state arrested in development, resulting in an obvious split crop and delayed maturing. Performance of runner varieties depended on location, but averages across locations in 2022 indicate that cultivar Lariat was the top entry in value per acre. The small-seeded runner-type cultivars AT98-99 and Span17 were the leaders in value per acre among the spanish trial entries. Significant differences were noted in virginia entry yields across locations and years. Cultivars Contender and Comrade were consistently top performers for value per acre among those currently grown. Results of these annual trials can serve as a guide for producers when choosing a cultivar to plant. USDA is an equal opportunity provider and employer.
