Our robust sorghum testing program consists of separate dryland and irrigated forage and grain sorghum hybrid performance trials.  Trials mainly consist of varieties and hybrids entered and paid for by commercial seed companies.  Sometimes hybrids that are widely grown in our region are added as commercial checks.  Our sorghum trials are partially funded by the Colorado Sorghum Producers Association.
