Abstract
The study was aimed to assess the effect of a biostimulator (S) and a herbicide (H) on weed infestation as well as qualitative and quantitative yield parameters of Mandaryna variety spring wheat. The experiment was conducted in north-eastern Poland conditions (2017–2018). The research consisted in using the herbicide (H) – sulfosulfuron and the biostimulator based on humic substance (S) in the H, S, H + S configuration. The herbicide was applied in the BBCH 31 phase, and the biostimulator – in BBCH 32, 47 and 69–71 phases. The treatments with the humic biostimulator reduced the effectiveness of herbicidal protection in weed biomass reduction. It was observed that weed biomass increased after using the biostimulator without any herbicide. In 2017, the highest wheat yield (4.5 t/ha) was obtained after herbicide application, and in 2018 after biostimulator application with the herbicide (5.0 t/ha). No significant effect of the biostimulator use on the qualitative parameters of spring wheat grains (protein, starch, Zeleny sedimentation index) was recorded. Celem pracy była ocena wpływu biostymulatora i herbicydu na zachwaszczenie oraz parametry jakościowe i ilościowe plonu pszenicy jarej odmiany Mandaryna. Doświadczenie przeprowadzono w warunkach północno-wschodniej Polski w latach 2017–2018. W badaniach zastosowano: herbicyd (H) – sulfosulfuron oraz biostymulator na bazie kwasów humusowych (S) w układzie: H, S, H + S. Herbicyd zaaplikowano w fazie BBCH 31, a biostymulator w fazach BBCH 32, 47, 69–71. Zabiegi biostymulatorem humusowym zmniejszyły skuteczność herbicydowej ochrony w ograniczaniu biomasy chwastów. W przypadku użycia biostymulatora bez wcześniejszego zastosowania herbicydu zaobserwowano zwiększenie biomasy chwastów. W 2017 roku najwyższy plon pszenicy (4,5 t/ha) uzyskano po zastosowaniu herbicydu, a w 2018 roku po aplikacji biostymulatora z herbicydem (5,0 t/ha). Nie odnotowano istotnego wpływu zastosowania biostymulatora na parametry jakościowe ziarna pszenicy jarej (białko, skrobia, wskaźnik sedymentacyjny Zelenyego).
