1. Evaluation of Nitrogen Fertilizer and Rhizobium Inoculation to Improve Grain Yield and Quality of Soybean and Dry Bean in Eastern Montana

Interest in production of irrigated soybean and dry bean in eastern Montana’s Lower Yellowstone River Valley increased substantially following the closure of a sugar beet processing facility in Sidney, MT resulting in the need for a replacement crop(s) on 30,000 to 40,000 acres annually. Yields of soybean and dry bean in this region varied significantly from 20 to 80 bu ac-1 in recent growing seasons, indicating a need for improved management practices. However, research-based... B.
