Effect of crop species, tillage, and rye (Secale cereale) mulch on sicklepod (Senna obtusifolia)
1996
Brecke, B.J. | Shilling, D.G.
Field studies were conducted to determine the effect of crop species, tillage, and rye mulch on sicklepod growth. Competition from soybean and sunflower reduced sicklepod biomass by 19 and 77%, respectively. Sicklepod height was reduced by rye mulch. Rye root residue caused 49% reduction in sicklepod biomass, while whole plant rye mulch reduced weed growth an additional 12%. Crop competition reduced sicklepod shoot biomass to a greater extent when rye residue was present. Crop seed yield was 32% lower in tilled plots compared with no-tillage due to more weed competition in the tilled plots. In the presence of rye root residue, soybean yield showed a two-fold increase over no mulch or whole plant rye mulch. Sunflower yield increased by 30% in the presence of rye residue compared with no mulch.
