Around fifty farmers from Uttar Pradesh were stopped from entering neighbouring Haryana's Karnal district on Monday to sell their paddy crop at government-run mandis (wholesale markets), despite the controversial farm bills - which promise barrier-free trade at markets and prices of the farmer's choice - having been signed into law on Sunday night. The Karnal Deputy Commissioner, Nishant Yadav, issued orders on Saturday to prevent farmers crossing the state border to sell non-basmati varieties of rice - which the Haryana government buys at a MSP (minimum support price) but the UP government does not.
