Reaction of Oak Prudence soybeans to foliar fertilization with macro-and micro-fertilizers in the conditions of the Orel region

The range of modern domestic and foreign fertilizers is constantly growing. Now the composition of fertilizers for foliar fertilizing, in addition to the main macronutrients, includes a large amount of trace elements necessary in a specific growing season. Such fertilizers are convenient for the use in tank mixtures with pesticides and are quite popular nowadays. This work is devoted to the comparative analysis of five different combinations of fertilizers: Basaplant (Germany), Nutrimix (EuroChem, Russia), water-soluble fertilizer NPK 20-20-20 (EuroChem, Russia) as a soybean foliar fertilizing in the Orel region. As a result of the research, it was found out that the use of foliar fertilizing has a positive effect on the yield and quality of soybean variety Oak prudence. In terms of soybean yield in comparison with other options, the option with The EuroChem 20-20-20 fertilizer proved to be the best one, which indicated the efficiency of its use in the conditions of the Orel region. High yield of soybean grain in the studied fertilizer application options was due to a large number of beans and seeds on the plant, as well as high seed productivity of these options. The optimal values of the acid index of the oil had variants with EuroChem+Nutrimix and EuroChem 20-20-20. The calculation of the economic efficiency of soybean cultivation based on the variants of the experiment showed that it was the most profitable to cultivate soybeans in the conditions of the Orel region with the use of EuroChem 20-20-20 fertilizer. The profitability of this option was the maximum and amounted to 65%. The use of alternative more expensive fertilizer Basaplant (Germany) as a foliar fertilizer leads to an increase in the cost of production and reduces the profitability of production.
