The present study analyzes the spatial integration through cointegration analysis on the wholesale monthly prices of potato in five selected markets of Assam for the period January 2013 to December 2018. The results of the analysis revealed that markets under study are integrated. The Granger Causality Test reveals 1bi-directional and 8 uni-directional causations under different market situations. However, the study finds no cointegration between Sonitpur (Dhekiajuli) and Nagaon (Dhing) market. Kamrup Rural (Upharhali) market was identified as the leader market. The study suggests the need to focus on building an improved market information system, one that is able to disseminate timely market information about price, demand and supply of products as well as strengthen market infrastructure facilities inorder to increase the efficiency of potato markets in Assam.
