In the conditions of the Republic of Belarus there were presented the results of three-year studies on the use of microfertilizers for pre-sowing seed treatment and foliar nutrition of vegetative sunflower (Helianthus annuus) plants. Higher economic efficiency of the method at application of microfertilizers in the growing season at the phase of 6 leaves is shown; however, due to the low costs of seed treatment better economic results were obtained by using micro elements together with seeds. Research results showed that among the studied fertilizers the most effective were preparations for sunflower contained boron in dose of 10-11%. Large increase yielding capacity provided the introduction micronutrients in the growing season. Calculation of cost effectiveness of agricultural practices led to the conclusion that the obtained relative net income was approximately equal regardless of the application methods. However, the profitability of pre-sowing treatment due to lower costs significantly exceeded the processing for the growing season.
