Мария Тимофеевна Мухина The article analyzes the effect of cytokinin 0.4 g/l 6-furfurfurilaminopurin on the yield and quality of the sunflower variety Yubileyniy 60 in 2019-2020. In our experiment, we tried to show the mechanism of action when applied 0.4 g/l 6-furfurfurilaminopurine in three doses of 0.5, 0.75, and 1.0 g/l on the essential factors of plant development and high yield. The researchers obtained maximum sunflower productivity with 6-furfurfurilaminopurine treatment at a dose of 0.75 l/ha. It increased the leaf area in 2019 by 32.1% and in 2020 by 26.6%, 1000 seeds weight by 6.0 g in 2019, and 3.8 g in 2020 (3.8 and 6.4%). The studies found the highest mass fraction of crude fat in the dry matter of sunflower seeds in 2019 and 2020. It was in the variant sprayed at a dose of 1.0 l/ha and was 41.06 and 41.32% (on the control 38.29 and 39.16%, respectively). The yield increased to the maximum in 2019 at a dose of 1.0 l/ha. It was 22.6% higher than the control variant (4.38 t/ha), and in 2020 the same variant was 0.57 t/ha (16.6%) higher than the control variant (3.07 t/ha).
