Efficiency of foliar fertilization in table grapes cultivation under irrigation

Purpose: to assess the impact of foliar nutrition with soluble fertilizers Plantafol and Boroplus on economic biological indicators efficiency cultivation table grape varieties in dry conditions under irrigation. The relevance research is due problem ensuring food security at national regional levels. Materials methods. subject was Codryanka (early), Rizamat (medium) Moskovsky (late). studies were carried out period 2015–2017 Astrakhan region. Irrigation depending phase development a rate 500–2250 cubic meters per hectare. timing fertilization treatment tied phases, rates accordance manufacturer's recommendations. methodological basis M. A. Lazarevsky B. Dospekhov calculation actual costs associated technological operations, fertilization, irrigation, protective measures, collection main additional products. Results. most cost-effective combined use plantations. variety distinguished. Conclusions. application plantations average for significant all three Kodryanka, during fertilizers, especially variety, when growing receiving products which cost price decreased by 24.6 %, reaching minimum value 14947.4 rubles/t, profitability increased 234.5 payback up 3.35 rubles/rubles.
