METHOD OF INCREASING SUNFLOWER YIELD Russian patent published in 2023 - IPC A01N43/40 A01N43/50 A01N53/14 

FIELD: agriculture.

SUBSTANCE: method of increasing sunflower yields in the soil and climatic conditions of the Ryazan Region includes tillage and sowing operations, while winter wheat is used as a predecessor, after harvesting which the stubble is peeled. In the spring, for the main tillage of the soil after cultivation, mineral fertilizers N₁₂₀P₆₀K₆₀ are applied and then in the second ten days of May, seeds of sunflower hybrids Imeria KS or Kodizol KL are sown into the prepared soil at a planting depth of 4–5 cm with a seeding rate of 45.0 thousand seeds per hectare and post-sowing soil rolling is performed. During the growing season, crops are treated with the herbicide Eurolighting at a rate of 1.2 l/ha and the insecticide Fastak at a rate of 0.15 kg/ha in the phase of 5–8 true leaves.

EFFECT: proposed method of increasing sunflower yields ensures a high and stable yield and accelerates the ripening of sunflowers.
