METHOD OF GROWING ONIONS AND POTATOES USING BIOLOGISATION Russian patent published in 2024 - IPC C05G3/60 A01P3/00 A01P7/04 A01P13/00 A01P21/00 

FIELD: agriculture.

SUBSTANCE: method of growing onions and potatoes using biologisation involves selection of a predecessor, tillage and harvesting, wherein the precursor used is potatoes for growing onions, after autumn plowing, spring pre-sowing treatment of soil is carried out – harrowing, then one week later, pre-sowing cultivation at depth of 8-10 cm, before sowing, mineral fertilizers are applied in a dose N₁₆₀P₁₀₀K₁₀₀, simultaneously applying phosphogypsum in dose of 8-10 t/ha and a liquid preparation "Baikal EM-1" in concentration of 40 ml/4 l of water, separate sowing of onion seeds is carried out using a row method with a seeding rate of 1 million pieces/ha, and winter wheat is used as a precursor for planting potatoes, cutting ridges to depth of 8-10 cm with a norm of tubers of 3 t/ha, then for separate vegetative plants, for onions before emergence, treatment is performed with Goal herbicide complex in dose of 0.2 l/ha + insecticide Karate Zeon in dose of 0.4 l/ha + biostimulant Isabion in dose of 1.0 l/ha with a working solution at flow rate 300 l/ha, then, in phase of onion leaf emergence, after inter-row treatment of soil, treatment with herbicide Boxer in dose of 1.5 l/ha + herbicide Goal in dose of 0.5 l/ha, one week after treatment, performing complex treatment with fungicide Quadris in dose of 1.0 l/ha + Isabion in dose of 1.0 l/ha + insecticide Karate Zeon in dose of 0.4 l/ha with a working solution at a flow rate of 300 l/ha, at that, for potatoes planting, tubers are pre-treated with a complex stimulator Immunocytofit with concentration of 1 tabl./4 t of water with a working solution at a flow rate of 10 l/t + an insectofungicide Prestige in dose of 1.0 l/t with a working solution at a flow rate of 10 l/t, then during vegetation the plants are repeatedly treated with a complex of insecticide Decis Expert in dose of 0.075 l/ha + Ridomil Gold MZ in dose of 2.5 l/ha with a working solution at consumption of 300 l/ha.

EFFECT: invention makes it possible to reduce crop losses in agrocenoses of onions and potatoes.
