Abstract
Glyphosate is used in plant production as a non-selective herbicide and harvest aid. Laboratory and field experiments were performed, which aimed at determining the effect of pre-harvest desiccation on grain quality and volunteer winter wheat. We investigated an effect of glyphosate applied at the dose of 1.0 kg ha -1 and 2.0 kg ha -1 at maturity stage (BBCH 85-87) on physical characteristics of grain, germination energy, germination capacity, seedling emergence capacity from various depths and on the density and weight of volunteer wheat seedlings in cultivated field. It was found that glyphosate applied at the dose of 2.0 kg ha -1 decreased the thousand grain weight and already at the dose of 1.0 kg ha -1 decreased the grain germination energy, length and weight of primary roots. Wheat desiccation with the use of glyphosate at the lower dose also limited emergence and the weight of seedlings with deep (10 cm) placement of grain in soil, and after the application of 2.0 kg ha -1 the seedling weight decreased by sowing of grain already in depth 4 cm. The pre-harvest desiccation limited the density of volunteer and weight of shoot winter wheat seedlings in the field.
