Study of new elements of technology for cultivating a medium-ripening melon variety

Relevance. Due to climate change on the planet, it is becoming increasingly difficult to obtain high yields of melons and melons in rain-fed conditions. Therefore, it is necessary to develop modern methods of growing them. Accordingly, the use of new water-soluble fertilizers for the cultivation of melon in hot climates is a relevant work at the moment.

Material and methodology. Objects of research: medium-ripening melon variety GP 599f and watersoluble fertilizers Lignohumate, Energen Extra, Zinc Sulfate. We have carefully studied options using these fertilizers for double foliar treatment of plants during the growing season.

Results. As a result of studying new types of water-soluble fertilizers on increasing the vegetative mass of plants, yield and biochemical parameters of the variety sample, a positive effect was revealed. As a result of a comparative analysis of data on plant development after double treatment with the studied preparations, an increase in canes in all variants was noted in relation to the control by 4.3-18.7%. When calculating the yield in all studied options, an increase in these indicators was noted in relation to the option without treatments. After treating the plants with new types of fertilizers, the yield was 13.4-15.9 t/ha. The average fetal weight varied from 1.7 kg. up to 1.8 kg with maximum values in the Lignohumate and Energen Extra options. An analysis of the comparison of the biochemical composition of fruits showed that new types of fertilizers did not affect the taste and purity of the products. The dry matter content was noted to be 0.8-1% higher than the control variant. Nitrate levels in fruits did not exceed the maximum permissible concentration (90 mg/kg) and amounted to 24-28 mg/kg.
