The study is an attempt to examine the variation in distribution pattern and factors influencing the marketed surplus of potato in two selected areas of Bangladesh. It shows that on an average 89 percent of potatoes are sold, of which 71 percent during harvest time and 18 per cent in the latter period. Small farmers sell relatively higher portion of their produce in the harvest time, compared to other groups of farmers. Except in few places, over-all marketed surplus of potato in the country has increased over the years. Production and marketed surplus of potato move in the same direction. Marketed surplus in absolute term is directly related to farm size but it is not true for the marketed surplus in percentage term. Cash income is not significantly influencing the marketed surplus. Land under potato is the most important factor determining the marketed surplus of potato.
