METHOD FOR CULTIVATION OF SUNFLOWER AND MIXTURES THEREOF IN TERMS OF SOWING FOR SILAGE IN CRYOLITE ZONE CONDITIONS Russian patent published in 2021 - IPC A01B79/02 A01G22/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to field fodder production. Method includes autumn ploughing, in spring at approach of physical ripeness of soil, moisture closure in 2 traces, disking in 2 traces, presowing treatment with simultaneous introduction of mineral fertilizers in dose N₆₀P₆₀K₆₀ kg/ha of active substance and pre-sacking. Sowing with post-sacking packing of annual fodder crops - sunflower, sunflower + spring vetch, sunflower + field pea, sunflower + Sudan grass, sunflower + millet, sunflower + maize, sunflower + oil radish, sunflower + spring rape, sunflower + amaranth - for two sowing periods. First seeding period - the first decade of June, the second period - the second decade of June ordinary manner with aisles 45 cm, with standard irrigation 250–300 m³/ha at 70–75 % field moisture capacity. Crops of the first sowing period are cleaned in the second decade of August with yield from 32.3 t/ha to 39.9 t/ha of green mass, the second sowing period is in the first decade of September with yield from 29.3 to 36.2 t/ha green mass.

EFFECT: method ensures cultivation of sunflower and its mixtures in terms of sowing terms for silage in cryolite zone conditions.
