With the increase in commercialisation of agriculture, the share of farm produce that is sold within the state shrinks and the share sold outside increases. Moreover, consumption patterns in the country are getting diversified largely due to an increase in per capita income. People want to consume a range of products often grown outside the state and even outside the country. This necessitates seamless flow of farm produce across the country without regulatory restrictions and barriers and excessive intermediation. This requires supply chains and value chains that move products from one state to another state quickly and efficiently and integrate consumer with producer at distant geographies. Such development is accelerated if we have uniform rules of game across the country with freedom to farmers and traders to sell, buy and move produce without unnecessary checks and barriers. Such 'one nation one market' is vital to raise price realisation by farmers, supply food to the consumer at competitive prices and to compete with import and push export.
