Fertirrigation technology on vineyards with economy of water and fertilizers for high-quality production of grape

The article provides information about the origin and essence of the word fertirrigation , the use of inorganic, solid fertilizers to obtain high yields from agricultural plants, as well as the use of fertilizers by dissolving them in water. Theoretical information on fertirrigation has shown that by dissolving fertilizers in water and introduced into the soil through the roots of plants, not only the productivity of the plant increases, but also the soil is enriched with nutrients for subsequent years. It was noted that the experiment on grape plantations was carried out in two versions: furrowing and fertirigation technology, where the irrigated area was 190 m2, the number of grapevines was 42. During the research, 1442 m3 of water was supplied per hectare when irrigated with injection fertirrigation technology, and 3810 m3 when irrigated by furrows. It was found that, compared with the furrow irrigation method, when using injection-ferrigation technology, due to the saved amount of water, the area of vineyards can be increased by 2.4 times. For furrow irrigation, N60P180K60 was applied, and for the injection method of fertirrigation, a dose of N24P70K24 was used, and the fertilizer savings were 2.5 times. This means saving fertilizers and eliminating negative impacts on soil quality. It was shown that the yield with the injection method of fertirrigation is 70 c/ha higher than with furrow irrigation, and the amount of nitrate nitrogen in the quality indicators of the product is46.5 mg/kg, i.e. less than 60 mg/kg (criteria).
