Slesareva, T.N.
The article presents the results of determining the optimal timing of application and effective substances with non-biocidal activity to overcome herbicide stress from the use of herbicide Aktion with application rate of 2.0 liters/ha on vegetative plants in the cultivation of white lupine. The effect of substances with non-biocidal activity on linear growth, accumulation of organic mass, mass of nodule bacteria, productivity and quality of obtained products was evaluated. It was found that the application of substances with non-biocidal activity Bioterra Antistress, Izagri Vita, Epin extra in the phase of stemming provided the greatest reduction in toxicity from the use of herbicide Action on vegetative plants of white lupine. Significant seed yield increases averaged 0.53- 0.60 t/ha over the years of research in relation to the variant of herbicide Aktion application. Application of fertilizer with organic acids and microelements in chelate form enriched with microorganisms Bioterra Antistress; growth regulator Epin Extra; humic fertilizer with growth regulator Lignohumate mark B potassium in the phase of stemming reduced the content of alkaloids in lupine seeds by 12.5 - 25.0 % compared to the variant of herbicide application only. According to the data of chemical analysis of white lupine seeds on the variant of Bioterra Antistress fertilizer application, in the phase of stemming there was an increase in protein content by 1.2 % in comparison with the variant of Action herbicide application.
