Estimating Dig Date – Getting the Sample.
To pull a sample from a field, pick at least 3 – 4 representative locations in a field. Pull up about 4 adjacent plants (clump of 4-5 tap roots) from each location; keep the plants (clumps) from each location separate. Take one plant from one location and pull off all peanuts from that plant; then pull another plant from the next location and pull off all peanuts – continue to do this until you have at least 180 pods but no more than 220 (32 oz cup = about 200 peanuts). When you reach 180, continue pulling peanuts off that plant then stop. Call me (Tucker) 507-8862 to do peanut maturity checks.
