Todd Baughman, Texas AgriLife Extension peanut specialist, said variety trials have identified top performers for Texas conditions. In 2010 tests, Flavorunner 458, Tamrun OL07, and ACI 149 were among the top performers.
ACI 149 is being touted for its high yields and early maturity. “We need more tests on disease tolerance,” he said. “Until we see it on more acres we will not have a good feel on disease tolerance.”
TX055307 and TX055308 had good yield and high grades in Baughman’s variety trials. “Grades were improved compared to recent Tamrun releases,” he said.
TXL061816 and TXL071606 are early maturing lines developed from Burow’s program. Baughman also looked at a Florida variety, UF09303, for the first time last year.
“All the varieties we’re testing are high oleic,” Baughman said. “We haven’t tested any non- high oleic varieties for several years. The current market demands high oleic peanuts from Texas, so that is why we are only testing those lines.”
Baughman said Virginia trials included Gregory, Perry, Bradley, Bailey, AT07V, Champs, Suggs and Florida Fancy, to name a few. “We also had one experimental variety from Virginia and three high oleic lines from North Carolina.”
Baughman also commented on the effect of plant stands on yield. “We planted peanut on spacings of 1, 2, 3, 4, 5 and 6 seed per foot of row.
“We started this study with a cotton project,” Baughman said. “With lower populations, we get 80 percent or more of the seed up. At the higher rate, we get from 60 percent to 70 percent. We think the first seed takes much of the moisture from the soil and the second seed doesn’t germinate.
“We have found that we can lower our seeding rate and that higher seeding rates do not necessarily give us more plants.”
They’re also testing various seeding rates under several irrigation schemes. “We will continue to work on the potential to lower seeding rates. In West Texas’ cool planting conditions, we thought we needed more seed to get a stand.”
That may not be the case and peanut farmers may be able to save money without sacrificing yield potential.
