production to obtain optimum seedling emergence and uniformity requires high-quality seeds. Germination tests are used to evaluate the production of normal seedlings under optimal germination conditions ( Atwater, 1978 ; Geneve, 2008 ). However, these do not

Agriculture (USDA), 2016 ]. Poor crop establishment is a major problem in edamame. Poor seedling emergence and uneven crop stands appear to be the norm in field trials, from North Dakota ( Duppong and Hatterman-Valenti, 2005 ) to Georgia ( Rao et al., 2002

some management techniques might translate from grain-type soybean to edamame, research to confirm or deny their appropriateness is lacking. Poor emergence is a common theme in field research on edamame ( Duppong and Hatterman-Valenti 2005 ; Rao et al
