The finding indicated that, the seasonal indices of arrivals reached their maximum during the harvest season and correspondingly decrease during the post-harvest seasons. Seasonal indices of prices decreased in harvest season and when the arrivals decreased, price increased in post-harvest season. Similarly, negative correlation found between the arrivals and prices of potato in certain year, indicating that prices of potatoes were independent on market arrivals in the regulated market.
