Abstract
Selenium (Se) is identified as an antioxidant and anti-carcinogenic and increasing Se the peanut (Arachis hypogaea L.) plant could benefit human and animal health. In 2006, Se was applied to soil at two locations and four concentrations to determine Se concentration in the peanut plant. Selenium (Sodium Selenite) was applied at rates of 0.5, 1.0, 5.0 and 10 mg Se/kg soil. Prior to harvest, plant samples were collected, washed, partitioned, dried, and ground to pass through a 2 mm sieve and analyzed for Se. Composite soil samples were taken prior to peanut digging, air dried, and analyzed for Se. In general, the higher the concentration of Se applied to the soil the higher the concentration of Se in peanut leaf, stem, root, peg, kernel, and hull. There was no difference in Se concentration between sites for leaf, stem, root, or pegs. There was a difference of Se with hulls and kernels between sites possibly attributed to soil series. Pooled data over both sites showed the untreated areas had an average 0.495 mg Se/kg kernel. The 0.5Se and 1Se treatment had an average Se concentration of 3.97 mg Se/kg kernel which could decrease the quantity of peanuts a person would need to consume from 760 to 14 g/day to get the needed requirement of Se. The treatments 5Se and 10Se averaged 16.1 mg Se/kg kernel. Adding Se to the soil can increase Se in the peanut kernel and plant which could be beneficial to human and/or animal health. However, application of high grade Se to peanut land at 0.5 mg Se/kg would cost about $526/ha which may not be economical for the grower.
