Abstract

In the conditions of drought in 2021-2022, potato yield in the forest–steppe zone of the Chelyabinsk region with the use of fertilizers based on a yield of 40 t/ha (N132P143K158) provided an increase in yield of 28.1-36.4% compared to the control (without fertilizers), and based on a yield of 60 t/ha (N260P260K285) – by 60.2–66.7% depending on the variety. With a planting density of 95 thousand tubers / ha (75x14 cm), the yield of the Cavalier variety turned out to be 18.6 t / ha, Amulet – 17.0 t / ha, Zakhar – 16.1 t / ha, Kashtak – 15.2 t / ha more than with sparse planting (75x33 cm). Watering potatoes in a critical period with respect to moisture provided an increase in the yield of Cavalier tubers with a sparse planting scheme (75x33 cm) by 7.4 t/ha (37.5%), with a 75x19 cm scheme – by 9.9 t/ha (33.1%), with a 75x14 cm scheme – by 10.4 t/ha (28.3 %) compared to the option without watering. In the Zakhar variety, the yield increases amounted to 5.8 t/ha, 7.9 and 9.3 t /ha, in the Amulet variety – 5.4 t /ha, 7.8 and 8.7 t /ha, and in the Kashtak variety – 5.2 t /ha, 8.3 and 9.1 t/ha, respectively.
