Barley–lentil (left) and barley–pea (right) alternate-row intercropping at the University of Idaho, Aberdeen Research and Extension Center. The seeding rate is 800,000 seeds/ac and 400,000 seeds/ac for monoculture and intercropping barley, 174,089 seeds/ac for intercropping pea, and 263,157 seeds/ac for intercropping lentil. No N fertilizers were applied in 2020 or 2021.
