The study was undertaken to analyse the economics of marketing potatoes by farmers in some selected areas of Sadar Upozila of Naogaon district. The study reveals that average potato production is positively related with the size of farm under potato cultivation. The per farm sale was the highest ( 152 quintals) for large farms and the lowest (42 quintals) for small farms and the largest volume of sale (69%) was made at thee market place. The major elements of marketing cost of farmers are transportation, storage and wastage. The study reveals that higher proportion of potatoes (36%) kept for table purpose were stored at home while higher volume of potatoes (33%) used for seed purpose were stored in cold storage. The findings indicate an inverse relationship between farmer's net share and the length of marketing channel i.e. the larger the marketing channel, the lower was the farmer's net share.
