Rye variety Sударushka is a highly cold-resistant cereal crop with pronounced aggressiveness in weed control, including perennial weeds such as quackgrass and sow thistle. Thanks to its roots, rye releases substances that restore soil health, suppress disease pathogens, and reduce nematode populations—microscopic plant parasites. Sown rye not only protects the soil from wind and water erosion but also improves its structure by increasing looseness and aeration, while enriching it with nitrogen, potassium, and organic matter when used as green manure.
Sowing rye Sударushka is recommended in the central region of Russia from mid-August to the end of September, allowing the crop to grow to 20–25 cm before frost. Seeds are sown in rows or evenly, incorporating them to a depth of 3–4 cm at a rate of 1.5–2 kg per 100 sq m. In spring, when green mass reaches 40–50 cm, the rye is cut with roots and plowed in with the topsoil layer, which promotes rapid decomposition and improved fertility. To accelerate the fertilization process, the area is recommended to be watered or treated with effective microorganisms. Such soil preparation contributes to successful cultivation of vegetable crops such as potatoes, cucumbers, tomatoes, pumpkins, and zucchini.
Under conditions of the northern taiga zone with a sharply continental climate and acidic sandy loam soil, the Sударushka variety demonstrates good yield when sown in mid-August at a rate of 6.0 million grains per hectare. To increase productivity, treatment with humic fertilizer from peat Gumorstim during tillering and stem extension is recommended. This approach allows the crop to adapt to complex climatic conditions and ensures stable growth and development of rye.
