Under current conditions, ecological component is becoming increasingly important. Restoration of potential soil fertility by their saturation with organic matter of intermediate crop siderates is the basis for growing environmentally friendly and high-quality products. Development and adaptation of effective agricultural technologies for growing potatoes in order to obtain organic products is an important scientific area today. One of the tasks of our research was to identify the payback of organic farming elements at current prices, in particular material resources directed on obtaining maximum and quality of potato harvest in the process of its growing. The results of farming and economic efficiency of using intermediate cultivation crops on green manure while growing potato are given. As a result of the conducted research was revealed positive influence of intermediate crops of sideral crops on economic efficiency of potato growing. Application of post-harvest Raphanus sativum siderate provided the highest yield of potato tubers – 30.9 t ha-1 and starch yield – 4.08 t ha-1. In the case of post-harvest Raphanus sativum siderate when growing potato, the highest net profit was obtained – 1369 € ha–1 and an additional profit of 460 € ha–1. Application of post-harvest Raphanus sativum siderate provided the lowest cost of potato growing – 36.35 € t–1, and the highest profitability level of its cultivation – 121.7%, with a payback of additional costs – 0.43 € t–1.
