Abstract
Abstract Field experiments in North Carolina in 1994 and 1995 determined virginia-type peanut (Arachis hypogaea L.) response to PGR-IV, a commercial hormonal growth regulator consisting of 30 mg/L of gibberellic acid, 27 mg/L of indolebutyric acid, and a proprietary fermentation broth. Treatments included PGR-IV applied once at 438 mL/ha 21, 45, 60, or 75 DAE (days after peanut emergence) or twice at 219 mL/ha at 21 and 45 DAE or 45 and 60 DAE. PGR-IV had no effect on peanut main stem or cotyledonary lateral branch length, yield, maturity, percentage of fancy pods, extra large kernels, or total sound mature kernels, or net returns.
