Abstract: 
An alfalfa variety trial was established in August, 2011 at the Central Oregon Agricultural Research Center in Madras, Oregon. The trial includes ten conventional varieties and seven Roundup Ready varieties. Yield and quality data were collected under a 4-cut management system over four production seasons from 2012 to 2015. Results indicate average annual hay yields of 8.5 to 11 tons/acre and average Relative Feed Value (RFV) ranging from 145 to 160, largely in the Premium quality rating. Initial stand establishment and stand longevity were 90 percent or better across all varieties.
