In the trial we compared the influence of row spacing (66 cm, 75 cm, 90 cm) on potato (Solanum tuberosum L.) yield. Cultivars Agria, Bright and Carlingford were included in the trial. We established that the highest total yield was by row spacing (RS) 66 cm, then by RS 75 cm and the lowest by RS 90 cm. The highest percentage of market yield had cultivar Agria by RS 66 and 75 cm, then cultivar Bright (the highest yield was by RS 90 cm, then 75 cm and 66 cm). The least percentage of market tubers was by cultivar Carlingford. There were no statistical significance. By RS 90 cm was the least number of green tubers, a little higher by RS 75 cm and the highest by 66 cm. In examining brown spottiness, second growth, tuber crashing, dry weight and percentage of starch we established that RS did not have influence on these properties, because they depended on cultivar.
