The results obtained proved that winter rye grown on black earth, which belongs to the IIa valuation class, produced a high yield regardless of cultivar, and that the herbicides applied did not have any phytotoxic effect on the growth or development of plants. Neither the yield nor the weight of 1000 grains were significantly affected by the use of herbicides or the date of their application. Their effect varied depending on the course of weather in the growing season. The herbicides tested did not significantly affect such characteristics as protein content, falling number, seed grading and bulk density, flour efficiency, volume and overbake of bread and porosity of crumb. Rye production in Poland occupies a significant acreage – 2350000 ha. It is assumed that more than a half of the rye plantations require herbicide treatment. Therefore the proper selection of an effective and selective herbicide for a specific rye variety is of paramount importance.application/pdfenryeherbicidesquality graincultivarsinfo:eu-repo/semantics/article
