The article provides information on determining the loss during evaporation and water conservation of irrigation water supplied to grape plants in vegetative vessels studied in laboratory conditions using injection-ferritization technology, on the study of mineral fertilizers dissolved in water and applied under the plant, and on the growth of grape plants. It is shown that the vegetation experiments were carried out in two variants: fertigation technology and drip irrigation technology. As a result, it was found that the water level of the injector of grape plants in the growing vessels is 0.5 l/h, the duration of watering during the growing season was 264 hours, with 11 watering 132 liters of water were given. When using drip irrigation technology, the water consumption by a dropper is 0.5 l/h, the duration of irrigation is 336 hours, 168 liters of water were used with 14 times watering, which means saving irrigation water by 27% with ferritization. When using fertigation technology, it was found that inorganic fertilizers dissolve in water 10 times faster with forced mixing than in the absence of forced mixing. This makes it possible to apply fertilizers with water in less time and save its norms. Also, in the vegetative vessel with fertigation technology, the mother bunch of grapes in the budding phase was on average 14 cm larger than with drip irrigation technology.
