The effectiveness of plant growth regulators in potato cultivation in the forest-steppe zone

The work is devoted to the study of the use of growth regulators in potato cultivation in Western Siberia. The experiments were carried out on meadow-chernozem soil in the forest-steppe zone with the potato variety Alaya Zarya. Studies have shown that the use of plant growth regulators in potato cultivation in the forest-steppe zone is effective. The most optimal application of organomineral regulators for the formation of a high-tech crop nutrition system is seed treatment and foliar treatment with Lignohumate. At yields without preparations of 34.5 (background 1 – without fertilizers) and 40.9 (background 2 – N15P60), the use of Zerebra Agro and Lignohumate regulators contributed to the formation of 36.2 – 36.3 and 41.7 – 42.3 t/ha tubers, respectively. Growth regulators provided reliable gains on both backgrounds.
