“Spanco is an anomaly,” Godsey said. “It is not available in 2011. Better varieties are available.”
Virginia yield average in Caddo County tests was 3,839 pounds per acre with a 64 percent grade. “Yield and grade were hurt by pod rot,” Godsey said. “GA-08V was clearly the best variety in the 2010 Virginia test.”
The Custer/Blaine County test, located in Hydro, produced an average of 6,787 pounds in the runner trials. Grade averaged 68 percent. “Tamrun OL07 performed very well at this location and graded similar to other top yielding varieties,” Godsey said.
“Yields for the Spanish varieties were excellent,” he said, “approaching yields for the runner varieties.” Average yield and grade were 5,940 pounds per acre and 65 percent. AT 98-99-14 and Spanco were top yielding varieties.
“AT 98-99-14 has a runner growth habit but is typically graded as Spanish. It has consistently yielded well in this region.”
For Virginia type peanuts, average yield at Hydro was 6,128 pounds per acre. Grade averaged 67 percent. “Pod rot incidence was high but yields were still good,” Godsey said. That pod rot infestation prevented identification of significant difference in varieties. “But GA-08V performed well.”
The test in Love County was the first trial for the location. Average runner yield was 4,569 pounds per acre. Grade averaged 71 percent. Top varieties included Red River Runner, Tamrun OL02 ARSOK-35-1 and GA-09B. “Red River Runner also had an exceptionally high grade, making it by far the most profitable variety in 2010.
“Yields for Spanish varieties were also good.” Average yield for Spanish varieties was 3,985 pounds per acre with a 63 percent grade. Spanco was the highest-yielding Spanish variety.
Virginia types averaged 3,474 pounds per acre and 63 percent TSMK. “Pod rot incidence was not as high as other locations but still present,” Godsey said. “GA-08V was by far the best performing variety in both yield and grade.”
Godsey said both of the Georgia varieties, GA-09B (runner) and GA-08V (Virginia) performed well in 2010 trials but he cautioned growers that they have been tested in Oklahoma for only one year.
He encouraged growers to diversify varieties and to pay close attention to planting date and conditions. “Set a yield goal and stay with your plan,” he said. “That’s the recipe for success in 2011.”
