Growers still contemplating planting late-season beans should get them in the ground as soon as possible to avoid reductions in yield potential, according to Clemson University Agronomist Pawel Wiatrak.
Yield reduction has long been an issue for double-crop beans in the Upper Southeast. New varieties and the recent high prices for soybeans have helped growers attack yield drag in a positive way. The stakes are high in terms of increased production costs and reduced plant performance.
Wiatrak tested soybeans from Maturity Group IV through Maturity Group VIII at varying planting dates and says beans planted by May 20 produced the highest yields, regardless of Maturity Group. Not counting Maturity Group IV beans, which have not performed consistently well in the Clemson tests, beans planted from early to late-May consistently produced 55 bushels per acre and frequently topped 60 bushels per acre under dryland conditions.
