The article presents calculations of the economic and energy efficiency of herbicide and fungicide application in soybean crops in the Ukrainian Forest Steppe. In the first experiment the soybean varieties Aurelina, EС Commander and EС Navigator and five variants of herbicide protection were studied. In the second experiment, the soybean varieties Amadea and Aurelina and ten fungicide protection variants were tested. It was found that the highest indicators of conditional net income, profitability and coefficient energy efficiency in the soybean varieties Aurelina, EС Commander and EС Navigator were obtained by using post-emergence herbicides with the active ingredient Bentazon, Imazamox (2 l/ha) + Chisalofop-P-Ethyl (2 l/ha) – 525.1, 437.6 and 558.9 EUR/ha; 87.1, 73.6 and 92.0 %; 1.83, 1.70 and 1.90. The maximum conditional net profit, profitability level and coefficient energy efficiency of the soybean varieties Amadea and Aurelina were in the variant with pre-sowing seed treatment with fungicide with the active ingredient Fipronil, Thiophanate-methyl, Pyraclostrobin (2 l/t) and the use of the active ingredient Pyraclostrobin, Epoxiconazole during the growing season – 509.0 and 421.3 EUR/ha; 76.4 and 63.1%; 2.14 and 2.02.
