The object of research is onion, cultivated as an annual crop in the Nonchernozem zone of the Russian Federation. The aim of the research is to develop an improved technology for the production of bulb in an annual crop, providing a yield of 70-80 t/ha on alluvial meadow soils of the Nonchernozem zone. Research method - field test. It has been established that the probability of performing each technological operation should be at least 95%. Sowing the seeds, which are previously cleansed from the rot, must be done at an earlier date. The required yield was achieved at N 200 P 160 K 280 + Humic chemical "Rostok" + 10 l/ha BisolbiSan, Azotovit, Phosphatovit biopreparations in equal proportions. The use of the microbiological preparation BisolbiSan in 1% concentration with chemical two-component fungicides (excluding copper-containing ones) increases the immunity of onion plants. In conditions of warm, humid summer, fungicidal treatments of onions are optimal at intervals of 7-10 days from the third decade of June to the end of July. The maximum weed suppression is provided by the post-sowing application of the Stomp Professional + Dual Gold tank mix (3 + 1 l/ha) in combination with the subsequent pre-emergence treatment with Reglon Forte (2 l/ha) and the post-emergence Goal 2E (0.5 l/ha).
