Malt barley properties for three cultivars (Harrington, Klagas, and Robust) were evaluated in response to agronomic treatments: cover crops, fungicide, or nitrogen treatments. In the fungicide study, the cultivar significantly influenced protein content, β-glucan, α-amylase activity, kernel weight, and germination energy. In the nitrogen study, all the measured properties were significantly affected by the barley cultivar. The moisture range of all the barley in this study was relatively low and within the acceptable range for malting. The plots not treated with nitrogen had a lower protein content under beans-wheat (b/w) cover crop. These low protein levels suggested an acceptability for malting. Robust had the highest germination energy. Harrington and Klagas grown under b/w cover crop yielded a heavier kernel weight in the fungicide study.
