A number of independent Corn Silage Hybrid Testing Programs are conducted across the country. Over the past two years the hybrid evaluation trials conducted in New York, Pennsylvania and Vermont have come together to develop a unified testing network. These efforts have involved Cornell University, Penn State University, the University of Vermont, the Professional Dairy Managers of Pennsylvania (PDMP), and the Western New York Crop Management Association. All of these programs were offering valuable information on hybrid performance, and this new unified collaboration further enhances these programs by allowing for the evaluation of hybrids across more growing conditions, as well as consistent analysis and reporting across sites.
