METHOD FOR INCREASING SOY PRODUCTIVITY ON THE BACKGROUND OF SHORT DAY LENGTHS Russian patent published in 2021 - IPC A01G7/06 A01N65/00 A01G22/40 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to plant growing. The method includes applying a solution of a gibberellin preparation to vegetative soybean plants. Vegetative plants of soybean varieties, highly sensitive to a shortened day, are sprayed with a gibberellin solution with a concentration of 0.003% (30 mg/l) in the "beginning of flowering" phase with a flow rate of the working fluid at the rate of 20 ml/m² (200 l/ha) of the area covered with soybean leaves. The area covered by soybean leaves is determined by measuring the total area of ​​their projection onto the soil. The phase "beginning of flowering" is considered the phase when the first flower appeared on 10% of vegetative plants.

EFFECT: method provides for obtaining more productive soybean plants under conditions of shorter day lengths.
