For potato-producer, the level of market yield, that he is able to sell, is an important factor of evaluation of cultivation technology. The relation of market yield to total yield determines percent of tubers with appearance defects and mass losses during storability at winter period. Yield level, share of tubers with appearance defects and storage losses of potato producing in organic, integrated and conventional systems were analyzed in this paper. Results show that it is possible to achieve yield with better parameters of market quality and storability in certified production systems than in conventional systems. Elimination or limitation of pesticides using not in all cases of defects category makes bigger level of losses. It was proved also that yield from organic production system is stored alike as from integrated system. The least effective is the system of low-cost technology of potato cultivation used in small farms.
