The purpose of this site is to provide information on the comparative performance of corn hybrids based on the data from replicated hybrid trials in various regions of North Dakota and adjoining areas in Minnesota.  Research has demonstrated the value of using data from multiple locations and years in selecting a hybrid. The primary focus of this site to provide information for the hybrid testing program conducted by researchers located on the main campus of NDSU. Links will be provided to all corn hybrid trials conducted by the Research Extension Centers and the NDSU Extension publication "North Dakota Corn Hybrid Performance Results", which summarizes the corn hybrid trial results for all of the state.
