The subject of the study is doses of mineral fertilizers, growth stimulants, microfertilizer, low-humus light loam chernozem. The purpose of the work is to develop innovative agrotechnical measures for the cultivation of winter rapeseed, which involve the use of complex fertilizers, microfertilizers and growth stimulants, which will ensure the realization of the genetic potential of winter rapeseed in the conditions of Western Polissia. Research methods. The research is based on field experiments using the following methods: counting and weighing - to determine the parameters of the crop structure and seed yield; chemical - to determine the content of nutrients in the soil, oil content; mathematical and statistical - to assess the reliability of research results; calculation and comparative - to determine the economic efficiency of cultivation technologies. As a result of the conducted research, the cultivation technology for winter rape in the conditions of the Western Polissia has been improved. Research in 2023 it was established that the best degree of overwintering of 86.3-88.2% was noted for fertilizer N35Р90К120 + N85S40 + N30, compared to N35Р60К90 + N85, where these indicators were within 80.1-80.8%. The highest survival of winter rapeseed plants during the growing season, 98.8-99.1%, was observed with the fertilization systems N35Р90К120 + N85S40 + N30 and with foliar feeding in the rosette phase and the beginning of budding Gulliver Stimulus + Avangard Silicon Bio (1.0 + 1.0 l/ha) and Gulliver stimulus + Avangard P phosphorus + potassium (1.0 + 0.6 l/ha) where the density of plants before harvesting is within 48.2-48.7 units/m2. On average, over the years of research, the best degree of overwintering of 78.8-79.3% was noted for N35P90K120 + N85S40 + N30 fertilizers, compared Product Description popup.authors popup.nrat_date 2023-12-13 Close
