applied: Axial (16.5 oz/acre), Maestro (1 pint/acre), Harmony extra (1/2 oz/acre). In the spring the Verdant field was fertilized with 50 lbs N/acre Urea (46-0-0) and 50 lbs N/acre custom blend (26-7-9-8) and the Alba field was fertilized at rate of 107 lbs N/acre custom blend (46-0-0, 18-46-0, 0-0-22 K-Mag). Fields were mowed one week Conventional Field Harvest and Quality Assessment: following heading for Alba and at heading for Verdant (May 17), raked (May 19), baled and then wrapped (May 21). After harvest, two bales from each field were weighed to estimate wet weight harvested, and multiple cores were taken from three Alba and three Verdant bales to estimate silage quality after ensiling for three months. Dry weight yield was estimated based on the average percent moisture of the silage samples and the wet weight of the bales harvested from each field. Feed acceptability was compared by feeding bales of Verdant and Alba side by side to a herd of beef cattle and noting preference. Results and Discussion When harvested at heading, Alba had a dry forage Organic Forage and Grain Quality: yield and quality comparable to Verdant (Table 1). Alba had significantly higher grain yield (Table 2). In this trial forage quality was superior to reference barley silage values and Alba grain feed quality compared favorably with reference barley feed values, except crude protein, which was about 1% lower (Stanton and LeValley 2010). This trial demonstrated the feasibility of Conventional Field Yield and Quality:
