Substantiation of the weed control system when placing grain production in microzones of the Central Chernozem region

Abstract

The most important link in modern farming systems is the protection of crops from weeds. Only by taking effective measures to reduce the weediness of crops one can get a high yield of cultivated crops and high-quality products. On a field or plot with high weediness all other agricultural activities aimed at increasing crop yields will be ineffective. When planning for weed control, the grower must give priority to preventive and organizational measures. It is much easier to prevent weeding of agricultural land than to try to weed an already weeded area. Preventive measures include: seed cleaning; preparation of feed for feeding, allowing them to be cleaned of viable weed seeds; preparation of organic fertilizers (manure, composts) before applying them to the fields. An important measure that reduces the weediness of fields is the destruction of weeds on lands adjacent to fields: on unused plots, field edges, roadsides, edges of forest belts. Cleaning of weed seeds from wastes is necessary by means of agricultural machines and vehicles, as well as by means of containers.
