Between-row treatments for weed management in day-neutral strawberry plantings in the northern United States
Locally grown strawberries are a high value crop, and the potential for a longer production season is possible with day-neutral cultivars. Weed control is ranked as a top concern for specialty crop farmers in the northern US. During 2019, we conducted a trial to determine if cover crops controlled weeds between rows as effectively as landscape fabric. We planted two strawberry cultivars, Albion and Cabrillo, with four between-row treatments at West Central Research and Outreach Center (WCROC), and an observational trial at Twin Cities Berry Company (TCBC). The four between-row treatments included winter canola (Brassica napus Torrington), winter camelina (Camelina sativa Joelle), winter ryegrass (Secale cereale Ryman), and landscape fabric. There were significant differences in yield among between-row treatments. Yield was equivalent between fabric and annual ryegrass. Canola produced significantly lower yield plant‑1 than either fabric or rye. There was no significant interaction with cultivar and between-row treatment, concluding between-row treatments operated similarly across cultivars. Cabrillo had a higher average yield plant‑1 than Albion regardless of between-row treatment. Our farmer-collaborator concluded he will continue using fabric on a commercial scale due to reduced time inputs for weed control compared with cover crops.
