Techniques for increasing tomato yield in Astrakhan region

Relevance. The use of mineral fertilizers in the cultivation of tomato in the first place should ensure the best conditions for the nutrition of plants during the entire growing season in accordance with their need. The research methodology was based on generally accepted methods for vegetable growing. The main goal of this study was to improve the zonal technology for cultivating tomato in open ground using leaf dressing with KCL and KNO3 preparations, aimed at increasing the level of yield during irrigation in the north of the Astrakhan region. Field experiments were carried out at the experimental irrigated land use area of the Federal State Budgetary Scientific Institution "Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences" in the period from 2021 to 2023. The scientific novelty of the study was the theoretical and practical justification for the use of leaf dressing with KCL and KNO3 in the cultivation of vegetables, aimed at the formation of highly productive commercial products.
