Soil-conservation effect of intercrops in silage maize

More than 50% of agricultural land is threatened by water erosion in the Czech Republic. With respect to soil erosion, maize (Zea mays L.) belongs most problematic crops; one possibilities increase protection against intercropping. In this study, we attempted find out effects individual intercrops and their mixtures (sown 4–6 weeks after sowing maize) or a mixed culture (maize plus lupine) on losses surface runoff period 2019–2021. The study was realised sugar beet growing region (Haplic Luvisol); field rainfall simulator used. From used variants with Lolium perenne L., Trifolium repens Vicia villosa Roth, multiflorum Lam., Festuca arundinacea Schreb., Triticum aestivum L. mixture (Vicia hybrid diploid), perenne, multiflorum, diploid, established between rows (hybrid maize, cultivar Walterinio) May 27, were efficient case both reductions year 2019. For example, mostly reduced similar (or higher) compared control without any intercrop). variant had higher similar) loss values (compared control); variant, lower control. We proved our hypothesis regards reduction perenne. results from years 2020 (the Secale cereale incarnatum Phacelia tanacetifolia Benth., incarnatum, pannonica Crantz) 2021 – early sowing, cereale, tanacetifolia, = Lupinus albus showed (Lolium incarnatum), (in 2020) incarnatum) albus) (2021) positive effect when > 2 m < 1 m. obtained 2019–2021 grasses decreasing mixtures.
