METHOD FOR APPLICATION OF BIOLOGICAL PREPARATION BY TECHNOLOGY OF GROWING EARLY POTATO VARIETIES Russian patent published in 2021 - IPC A01G22/25 A01N37/44 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method includes the selection of a precursor, the application of organic fertilizers, the planting of tubers and the application of mineral fertilizers. For planting, potatoes of early varieties with a growing season of 77-90 days are taken, and their cultivation is carried out in an intensive crop rotation, including pure steam. Winter wheat is used as a precursor of potatoes. Organic fertilizers are applied for the main treatment in the form of 40 t/ha of compost, and mineral fertilizers in a dose of N₁₄₀P₈₀K₁₀₀ kg of AI/ha. Tubers are treated before planting with the use of the biological preparation Izabion, and when growing early potato varieties, respectively, they are treated by spraying potatoes with a solution of the biological preparation Izabion in the phase of reaching shoots of 12-14 cm, then in the second phase of flowering and in the third phase of budding with an interval of 10-15 days after the second. Planting of early potato varieties is carried out in the first decade of May when the physical ripeness of the soil is reached, at a temperature in the ridge of 8°C to a depth of 8-10 cm.

EFFECT: method provides an increase in the consumer qualities of early potato varieties through the use of environmentally friendly technologies when using biological preparations together with mineral fertilizers.
