Field performance of Nineteen Runner-Type Peanut Cultivars/Genotypes in Mississippi County, Arkansas, 2024

by Michael Emerson, Brandon Baker, Nicole Emerson, and Travis Faske - February 17, 2025

National Peanut Board logo and Division of Agriculture logo Field performance of nineteen runner-type peanut (Arachis hypogea L.) cultivars/genotypes were evaluated in an on-farm peanut trial near Leachville, AR. Seeds were either foundation or breeder seed. Cultivars and/or genotypes were arranged in a randomized complete block design with four replications. Plots consisted of two row, 25-ft long rows spaced 38 inches apart, and separated by an 8 ft fallow alley. Seed were planted on 9 May at a rate of 6 seed/ft of row in a field previously cropped to cotton (2022 and 2023). Admire Pro (imidacloprid at 7.0 fl oz/A) and Primo CL (peanut inoculant at 7 fl oz/A) were applied in-furrow at planting at 9.4 gal/ac. Fungicides were applied as per farmers disease management program with at least three applications in the 2024 cropping season. Peanut plants were dug on Oct 10 (154 DAP) and thrashed on Oct 16 with a KMC 3020 two row thrasher equipment with a bagging system for small plots.

Data was subject to ANOVA using Agricultural Research Manager Software (version 2024.2) and means were separated using Tukey’s honest significant difference test (P = 0.05).

No foliar diseases were observed and only one or two small spots of southern blight caused by Athelia rolfsii were observed in the study. The southern blight incidence was minor and not included in these results. Root-knot nematode density at planting averaged 5 J2/100 cm³ of soil and decreased by the end of the season to 0 J2/100 cm³ of soil.

^aStand count is total number of plants per 10 row ft.

^bGrade (total SMK) was based on USDA standard for peanut and conducted by USDA graders at Birdsong Peanut in Portia, AR.

^cMoisture at harvest averaged 6 percent moisture across cultivars.

^dData are averages of four replications. Averages followed by a different letter within each column are significantly different at α = 0.05 according to Tukey’s HSD.
