In 2014–2020, in the conditions of the Tambov region, in a six-field grain-fallow crop rotation we studied the effect of mineral fertilizers on the productivity of sunflower variety Spartak of breeding of Tambov Research Institute of Agriculture. For the period of 2014–2020, the highest yield was obtained with the application of N30P30K30 + seed treatment with Megamix (2.0 l/t) and amounted to 2.84 t/ha. The most cost-effective of application of microfertilizers is the pre-plant seed treatment (4).
