Winter wheat (Triticum aestivum) is the most important crop in Latvia. The aim of this research was to compare winter wheat yields: when it is grown in two diversified crop rotations versus continuous wheat sowings, and to compare influence of the traditional and reduced soil tillage system on wheat yield. Research was conducted at the Research and Study farm “Peterlauki” in 2016/2017–2019/2020. Crop rotations used were: (1) continuous wheat, (2) three-year rotation (oilseed rape (Brassica napus) – wheat – wheat), and (3) four-crop rotation: faba bean (Vicia faba) – wheat – oilseed rape – spring barley (Hordeum vulgare). The results showed that significantly higher (p is less than 0.001) wheat grain yield was obtained in four-crop rotation with fore-crop faba bean, and also significantly higher yields were gained in three-year rotation with oilseed rape if compared to continuous wheat sowings. The soil tillage system did not influence the wheat yield.
