If you’re expecting a seed price of about $1.10 per pound, you’d be planting $123 per acre at five seed per foot, says Tubbs. But if you’re expecting to pay $1.45 per pound, at seven seed per foot, that’s $227 to plant an acre of peanuts, he adds.

“To change your seeding rate by one seed per foot, you’ll have to change your budget by $24.60 per acre. If you went from six seed per foot to five seed per foot, you’d be reducing your input cost by $24.60 per acre,” he says.

At a contract price of $600 per ton, a grower would need to make an extra 82 pounds of peanuts to pay for the extra seed cost.

Going from six seed up to seven seed per foot, at $1.45 per pound, and at a contract of $600 per ton, a producer will need 108 pounds of peanuts to make up for the extra cost.

Row pattern is a consideration on seeding rate, says Tubbs.

“For single-row peanuts, you’re planting a seed at 12 inches or 1 foot of row. You’ve got six seed per foot being planted — that’s a seed every 2 inches from an adjacent seed being planted. In a twin-row pattern, we’re taking out half of those seed and moving them over to an adjacent row.

“Looking at data from 2011 trials, 85 percent of our twin-row peanuts had survived by the end of the season. Seventy-three percent of the peanut seed in single rows survived. We used the same seeding rate and the same management.”

Part of the decrease in single-row plant stands is due to plant competition, and part of it is due to the speed of the seed plate as it’s spinning, says Tubbs, adding that there will be skips whenever you plant at too rapid a speed.

“We’ve typically seen twin rows yield better than single rows,” he says. “This isn’t true in every single case, but the vast majority of the time, we’ve seen from a 200 to a 500-pounds-per-acre increase in twin rows.”

Another seeding rate test, says Tubbs, looked at plant stand versus yield, regardless of the seeding rate.

“With the single-row pattern, there’s very little difference, on average, whether we’re looking at three plants per foot or five plants per foot. But with twin rows, we see that curve leveling off at about the four and a half to five-plants-per-foot range.
