Abstract (English):
On the leached chernozem of the Stavropol Upland in 2023-2024, field studies were conducted to optimize the use of liquid vermicompost doses on various backgrounds of the main fertilization. It was found that pre-sowing application of nitroammophoska N60P60K60 and vermicompost 3 t/ha provided approximately equal productivity levels of the Red Scarlett potato variety (15 and 14.2 t/ha, respectively), which is significantly higher than the control values. Foliar fertilization with liquid vermicompost in direct dependence on the fertilizer dose (1; 1.5: 2 l/ha) on all nutrition backgrounds of the main fertilization significantly increased potato productivity compared to the control by 1.2-5.0 t/ha, but increasing the vermicompost dose to 2 kg/ha did not provide a reliable yield increase. The highest dry matter and starch content in the experiment was observed in the variants with the main application of vermicompost at a dose of 3 t/ha and foliar application of liquid vermicompost at a dose of 2 l/ha. The highest potato productivity (20 t/ha) in non-irrigated conditions on leached chernozem was ensured by the application of 2 kg/ha of liquid vermicompost at the budding stage against the background of the main application of N60P60K60.
