Relevance. The determining value in modern melon production is to increase the yield and market yield of environmentally friendly products at minimum costs for the cultivation of melons. For the development of the melon industry in the agro-industrial complex of the Russian Federation, the scientific search for technological solutions aimed at creating conditions for increasing the yield and quality of melon products becomes urgent. Materials and methods. The object of research-melon, variety autumn. The types and doses of water-soluble fertilizers were studied: vegetable Aquarin, Novalon Foliar, and Hakafos. Fertilizers were used to treat plants during the growing season.Results.Studies have established a high effect of the use of water-soluble fertilizers on vegetating plants, which allow eliminating adverse environmental factors. The yield from the use of water-soluble fertilizers in melon cultivation technology for the years of studies is 31.3 86.7% higher compared to the control variant (without treatments). In more favorable climatic conditions of the year, the maximum yield was obtained in the variant with the use of Hakafos in a half dose, which had a more balanced content of nutrients compared to other studied water-soluble fertilizers –15.5 t/ha, which is 21.1% more compared to the minimum dose, 42.2% more compared to the treatment of plants with water and 1.8 times more compared to pure control. In the dry conditions of 2019 and lower air temperatures during the ripening period, a similar trend was noted. Comparative analysis of the biochemical composition of fruits showed that water-soluble fertilizers do not have a negative impact on the environmental purity of the product, the amount of nitrates for all years of research did not exceed the MPC (90 mg/kg). Studies have determined the positive effect of water-soluble fertilizers on improving the quality of fruits, the content of dry substances, one of the main indicators, in the study periods, exceeds this indicator in the control version (without treatments).
