  • By: Jared Whitaker The 2018 Georgia cotton season has started off as a tale of two extremes.  Rainfall during April and the first two weeks of May was almost non-existent, which delayed planting in some dryland situations and even made stand establishment with irrigation challenging.  Since then, rainfall has been plentiful if not excessive across…
