FIELD: agriculture.;SUBSTANCE: method includes pre-sowing treatment of seeds and vegetating plants with water solution of growth controller. As growth controller, "Verva" preparation is used, which was extracted from silver fir greens by method of emulsion extraction. Treatment is carried out once or twice per vegetation period with dose of preparation 4-5 g/ha of reactant. Sunflower plants are treated twice, in phase 2-4 of existing leaves, and then in the beginning of blooming with dose of preparation of 4 g/ha of reactant. Rape plants are treated two times: pre-sowing treatment is carried out with dose of 4 g/t, and plants are sprayed in phase of blooming start with dose of preparation of 5 g/ha of reactant.;EFFECT: improved crop capacity of oil bearing crops and oil content in seeds.;3 cl, 8 tbl
