Influence of predecessors, mineral fertilizers and humate on the infestation of crops with weeds and the yield of chicory roots

Relevance. For the cultivation of environmentally friendly products, the preservation of soil fertility and environmental protection, the question of the prospects for longterm use of various fertilizer systems is very important. With an acute shortage of manure, a mineral-biological fertilizer system is promising, when an estimated dose of mineral fertilizers is applied against the background of annually sown siderates. Such a system of fertilizer application makes it possible to increase yields, product quality, significantly reduce the shortage of organic matter in the soil, improve its structure and biological activity. The inclusion of the employed steam with the most effective precursors, doses of mineral macro and micro fertilizers and humic acids in the rowed link of crop rotation can reduce the contamination of crops and significantly increase the yield of root chicory root crops. Materials and methods. The research was carried out in 2017-2021 located in the Rostov district of the Yaroslavl region. Results. As a result of the conducted research, it was found that on turf-podzolic medium-loamy soils of the Non-Chernozem zone of the Russian Federation, it is economically feasible to use technology for the cultivation of root chicory using an oat-pea mixture as a precursor in combination with the introduction of mineral fertilizers into the soil at a dose of N60P60K120 and the treatment of vegetative plants with boron and humate. When using this technology, the contamination of crops decreases, their photosynthetic potential and the yield of root crops increases, the cost of production decreases, and the profitability exceeds 104%.
