Reported dry matter yields of currently existing sorghums with
biomass potential range from 15.6Mg/ha to 40.3Mg/ha across
many environments(Habyarimana et al.,2004;McCollumetal.,
2005; Rooneyetal.,2007;VenutoandKindiger,2008). For comparison, average US maize grain yields have been reported at9.3Mg/ha
(Egli, 2008) and in 2008 a switchgrass cultivar was released with superior dry matter yields of 15.7Mg/ha across two locations in North Carolina after a two year establishment period (Burns etal.,
2008).
