The influence of herbicides on the spring wheat production capacity in the forest-steppe zone of Krasnoyarsk krai

In modern conditions, the lack of human and material resources in the agricultural production has become an unavoidable reality, requiring essential transition to energy and resource-saving technologies. These condi- tions require the rethink of approaches to modelling of crop rotation schemes. Being the basis of the agriculture system, crop rotations define all other elements, tillage systems, fertilizers, erosion-preventive and land reclama- tion activities, their phytosanitary importance increases, including the plant protection from pests, diseases and weeds. The assessment of the influence of the energy and resource-saving technology elements of high ecologi- cal and economic efficiency based on the use of modern chemical means of plant protection in the field crop rotation on the effective soil fertility under the conditions of Middle Siberia forest-steppe zone, gives a possibil- ity to create real conditions for enhancing crop productivity, while reducing economic, labor and energy costs. The purpose of the research is the assessment of the influence of opposite-dicotyledons herbicides on the produc- tion capacity of spring wheat “Novosibirskaya 29” variety. The research confirmed the influence of herbicides Magnum, Puma Super 100, Zinger on the background of the fungicidal protectant, Tebu 60, on the agrophytoce- nosis and productivity of wheat “Novosibirskaya 29” variety in the experimental fields of СJSC “Iskra”. The farm is located in the area of Achinsk-Bogotol forest-steppe in Yelnichnaya village, Uzhursky district of Kras- noyarsk Krai. The research results can be applied in the cultivation of wheat in the Krasnoyarsk Territory forest- steppe conditions.
