Purpose: to determine elements of irrigation technology for young vineyard plantations using the drip irrigation method on various types of soil in the Republic of Crimea and test them under the conditions of this region.
Materials and methods. The research was carried out in the village of Pavlovka, Belogorsky district of the Republic of Crimea. The establishment of field experiments and observations were carried out using generally accepted methods for setting up and conducting field experiments.
Results. As a result of the research, the water-physical properties of soils of the Republic of Crimea were analyzed and rational elements of the technology for irrigating young vineyard plantations using drip irrigation on various types of soils (limits of optimal soil moisture, dripper consumption, wetted depth, irrigation period and water application rate) were calculated. When calculating the irrigation regime for the drip irrigation method, it is necessary to take into account the wetted layer depth, the physical properties of soil, the planting pattern, the moisture contour shape, the dripper flow rate and pre-irrigation soil moisture. The elements of irrigation technology for young vineyard plantations vary significantly, for example, the recommended flow rate of drippers varies from 2–4 l/h on chernozems to 6–8 l/h on light chestnut soils and steppe solonetzes, while the duration of irrigation varies from 2–3 h on light chestnut soils up to 6–9 h on ordinary chernozems.
Conclusions. When testing the results, it was found that the drip irrigation method has a positive effect on the survival rate of table grape cuttings. On average, this indicator for varieties was 98.8%. For soil and climatic conditions of the Republic of Crimea, the varieties Sport, Podarok to Irina, Baikonur and Zabava turned out to be the most responsive in terms of their morphological characteristics. During the growing season of the first year young table grapes (in a medium-dry year), 16 irrigations of 30 cubic m/ha with an irrigation rate of 480 cubic m/ha were carried out, while the total water consumption excluding the use of moisture from soil was 3740 cubic m/ha.
