Researchers find that single-cropping sorghum ideal for ethanol production

In Iowa, researchers at Iowa State University examined 12 varieties of sorghum grass grown in single and double cropping systems and found that using sorghum from a single-cropping system was more effective for the production of ethanol. The project’s lead says that from a production standpoint, growing sorghum as a sole crop is more efficient for ethanol production, however, it remains to be seen whether the favorable long-term environmental benefits, such as reduced erosion potential, of the double-cropping systems merits the reduced total biomass production.
