摘要

Peanut cultivar ‘GA 03L’ was planted on 24 May in a field with a history of peanut production at the Wiregrass Research and Extension Center in Headland, AL. Seed were sown at a rate of approximately five seed per ft of row, and recommendations of the Alabama Cooperative Extension System for tillage, fertility, weed, and nematode control were followed. The soil type was a Dothan sandy loam (OM<=1%). Plots, which consisted of four 30-ft rows spaced 3-ft apart, were arranged in a randomized completeblock with six replications. Plots were located under a central pivot irrigation system and watered as needed. Fungicides were applied on a 14-d schedule using a four row tractor mounted boom sprayer with three TX8 nozzles per row calibrated to deliver 15 gal/A. Early and late leaf spot were visually rated on 2 Oct using the Florida leaf spot scoring system. Counts of stem rot (SR) loci (1 locus was defined as <= 1 ft of consecutive symptoms and signs of the disease) were made on 16 Oct immediately after plot inversion. Plots were harvested on 26 Oct and yields were reported at 10.1% moisture.
