In the paper, an influence of potato irrigation on higher level of total yield and changing share of market yield in total yield were evaluated. Profitability of using of drip irrigation was calculated taking into account the expenses and value of yield. Is was shown that in case of drought during the vegetation period yield the increase of potato yield due to irrigation in ecological system may achieve up to 25 percent. Potato quality is improved which is expressed by increased market yield. Relative high cost of drip irrigation are fully refund by increasing value of potato market yield. It is also possible to use the irrigation for increasing biomass production which comes from intercrop production used for ploughing
