The effect of vermicompost on the yield and quality of watermelon fruits (Citrullus vulgaris) grown in the open ground

The article defines the effect of various amounts of vermicompost on the growth, productivity and chemical composition of the biomass of Citrullus vulgaris. In the research work, biohumus was used, made with the help of California worms at the educational base of the Aktobe Higher Agrarian and Technical College named after Sh.Bersiev, located in the village of Kenes Nokin, Aktobe region. Watermelons were grown in two different ways, grown with seedlings and seeds in the open ground, after introducing vermicompost into the soil. The results of biometrics have shown that the introduction of vermicompost into the soil has a significant effect on the growth and development of watermelons, the formation of their vegetative biomass, and an increase in yield. The yield of watermelon was observed on the basis of the introduction of vermicompost compared with the average weight of one watermelon by the observer, that is, an increase from 5.5 kg to 7.8 kg of yield was found and amounted to 16.5 kg/m2, which was 5.8; 7.8 and 45.4%, respectively, compared with the control. The content of dry substances, vitamin C and total sugar in watermelon fruits was within the permissible norm and above the control level. During the mass harvest of watermelon fruits, the nitrate content in the product was several times lower than the established norms (MPC for watermelon is 60 mg / kg), that is, the product is environmentally friendly [1].
