AB  - The aim of this work was to determine the photosynthetically active radiation interception (iPAR) during the cover crop (CC) growth cycle, the number and aerial dry matter (ADM) of weeds, and productivity in the following soybean and maize rotation crop. To do this, experiments with CC were performed in 2015-2016 using Hordeum vulgare L., Lolium multiflorum L., Avena sativa L., Bromus unioloides L., Vicia villosa L., Brassica campestris L., Raphanus sativus L., and Avena sativa/Vicia villosa. The iPAR at the vegetative and reproductive stage of CC and the number and ADM of weeds were determined. In Bromus unioloides L., iPAR in tillering was lower than in the other CC grasses (45% and 65%, respectively). In Vicia villosa and Avena sativa/Vicia villosa, iPAR was close to 100%. In cruciferous CC, iPAR percentages during 2015 were 77% in Raphanus sativus and 61% in Brassica campestris, whereas they reached 35% in 2016. No significant differences were recorded in soybean grain productivity, but in maize, productivity was maximum in Avena sativa/Vicia villlosa and Vicia villosa. All CC decreased weed number and ADM regardless of iPAR, thus showing that CC use leads to no productivity losses in the following soybean and corn crops and decreased the use of herbicides.
