Application of microbial preparation Planrhiz and fungicide Rydomil Gold MC 68 WG have improved yield, marketability of potatoes and have increased the standard part of tubers. Plants bakterization have promoted increase of potatoes marketability by reducing the number of small, mechanically damaged and sick tubers, with the crop yield higher than the control in 1,5–1,9 times while the number of sick tubers have decreased in 2,4–5,5 times. The combination of microbial agents (Planrhiz + Diazofit + Phosphoenteryn) compared to single application of Planrhiz have revealed no significant difference between the yield and product marketability. As for the planting terms – the 1st planting term in the third decade of April have showed to be the best in West Polissya due to the formation of bigger number of standard part of the tubers.
