Techniques for increasing the yield of various varieties of sweet pepper in the Astrakhan region

Relevance. The use of growth-stimulating fertilizers in the cultivation of sweet peppers should primarily ensure the best nutrition conditions for plants throughout the growing season in accordance with their needs. The methodology of scientific research was based on generally accepted methods of vegetable growing. The main purpose of this study was to improve the zonal technology of cultivating sweet peppers in the open ground using top dressing with Krepen, BP in various concentrations of 0.3 ml/300 ml of water and 1.5 ml/l of water, aimed at increasing the yield level during irrigation in the north of the Astrakhan region. Field experiments were conducted on a pilot irrigated land use site of the Caspian Agrarian Federal Research Center of the Russian Academy of Sciences in the period from 2022 to 2024. The scientific novelty of the study consisted in the theoretical and practical justification of the use of leafy top dressing with the preparation Krepen, BP in the cultivation of vegetable crops aimed at the formation of highly productive marketable products. Results. In the course of the research work, a comparative analysis of the various standards for the use of the drug Krepen, BP was carried out, highlighting the most promising option. Three-year studies have shown that the use of Krepen, BP after planting seedlings in the field gave a significant increase in yield relative to the control option. Conclusions. According to the results of the analysis, on average for five collections, a variant with a consumption rate of 1.5 ml /l of water was identified for the sweet pepper hybrid Honey F1, where the biological yield was 104.0 t /ha, commercial yield 101.0 t/ha, marketability 96.9%.
