Abstract: 
An alfalfa variety trial was established in August, 2011 at the Central Oregon Agricultural Research Center, Madras, Oregon. 2014 was the third production year of a four year project to generates yield and quality data under 4-cut management. Ten conventional varieties (including 2 industry standards) and seven Roundup Ready® alfalfa varieties are being evaluated in side by side replicated plots. During 2014 total yield for conventional varieties ranged from 8.5 to 11.8 tons/acre and total yield for Roundup Ready® varieties ranged from 9.7 to 11.7 tons/acre. Average relative feed value (RFV) ratings provide the best indication of overall quality, with all varieties rated Good (126-150) or better for each of the four cuttings. As expected, forth cutting RFV ratings were significantly higher than the three previous cuttings. Comparison of average quality scores across conventional and Roundup Ready® varieties show a similar performance with RFV ratings ranging from 144 to 160 for conventional varieties and 145 to 155 for Roundup Ready®.

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.
