Abstract: Introduction.The use of new water-soluble fertilizers in chelated form has not yet become widespread due to their poor knowledge.In this regard, the study of the effect of these drugs on the passage of the main processes of life of grapes in the arid conditions of th e North-Western Caspian region is relevant.Object.The object of research was table grape varieties of different ripening periods (Codryanka, Moskovsky, Rizamat) grown on light chestnut soils of the Vineyard of the Federal Public Budget Scientific Institution «Precaspian Agrarian Federal Scientific Center of the Russian Academy of Sciences» Astrakhan Region, Russia.Materials and methods.The purpose of the research is to study economically valuable characteristics of table grape varieties depending on foliar nutrition with Plantafol and Boroplus fertilizers in irrigated conditions of the North-Western Caspian region.The analysis of meteorological conditions was carried out according to the data of the meteorological station with.Black Yar.The evaporation rate of soil moisture was calculated using the formula of N.N.Ivanova.The actual water consumption for the production of 1 ton of grapes was estimated by the coefficient of water consumption.Results and conclusion.The efficiency of irrigation water use increases from control to joint application of foliar dressings in all three varieties.This pattern can be traced over the years and on average over three years.The water consumption coefficient in the control was: for the Kodryanka variety 783.6 m3/ t, for the Rizamat variety -846.3 m 3 /t, for the Moskovsky variety -758.9 m 3 /t.The use of Plantafol fertilizer reduced water consumption by 1 ton of crop for the Kodryanka variety to 609.0 m 3 /t, for the Rizamat varietyup to 546.4 m 3 /t, for the Moskovsky varietyup to 511.5 m 3 /t.When using the Boroplus fertilizer, the water consumption coefficient for the Kodryanka variety decreased to 454.1 m 3 / t, for the Rizamat varietyup to 406.9 m 3 / t, for the Moskovsky varietyup to 427.5 m 3 /t.The minimum indicator was noted with the joint use of Plantafol and Boroplus: for the Kodryanka variety -363.2 m 3 /t, Rizamat -361.4 m 3 /t, Moskovsky -374.2 m 3 /t.Key words: precipitation, moisture deficit, air temperature, total water consumption, water consumption coefficient, grapes.Citation.Polukhina E.V., Vlasenko M.V.
