The purpose of our research was to establish the economic efficiency of the use of growth regulators "Vermimag" and "Vermiodis" for presowing seed treatment and one and two-time spraying of sunflower seeds of hybrids NK Briio and NC Rocky in the conditions of the Forest-steppe of the West. It was established that the largest contingent net income was 18689 UAH / ha, profitability level - 116.1%, lowest cost of 4350 UAH / t was on the variant where pre-sowing seed treatment of sunflower hybrid NK Brio was carried out by the growth regulator Vermiodex in a dose of 4 liters / t in combination with two-time spraying with the drug "Vermiodis" in a dose of 4 l / ha. The results of our studies have shown that the use of humic preparations in sunflower growing is an economically feasible measure in modern technology for the Western forest-steppe zone, since the cost of the gains of yield of sunflower hybrids exceeds the cost of preparations and the cost of their use, especially when growth regulators are used simultaneously with pesticides that makes it possible to reduce the cost of its cultivation, contributes to the increase of gross output, reducing its cost, which is especially important from market conditions.
