Influence of a new complex biological fertilizer Yng-e Gyuntuk on the productivity and quality of melon crop and soil fertility

This article presents the scientific results on the effect of the biological fertilizer “Yng-e Gyuntuk” on soil fertility parameters in melon crops, phytosanitary condition, plant growth and development processes, crop productivity, and fruit quality. The study investigated and established the influence of the biological preparation on the phenological stages of development, biometric characteristics of melon plants, yield, and quality indicators of fruits. The results demonstrated that the application of the complex biopreparation enhances biomass accumulation in melon plants, improves growth processes and biochemical composition, and increases the content of macro- and micronutrients in the soil. The effect of the biological product on the phytosanitary condition of melon crops was also determined, and data on its biological and economic efficiency against a particularly harmful pest - the melon fly are presented. When plants were treated with the biological complex, the biological efficiency against the melon fly reached 87.42%, while soil application resulted in 88.13% efficiency. The biological fertilizer Yng-e Gyuntuk increased melon yield by 28.0-32.6% compared to the control.
