Punjab farmers are facing significant losses in potato crops due to a yield decrease by 20% and selling prices nearly 40% lower than expected, with prices ranging from Rs 350-400 per quintal instead of the expected Rs 600. The reduced yields and poor market prices are attributed to adverse weather conditions, including frosty January temperatures, and a larger, lower-priced crop in other regions. The Jalandhar Potato Growers Association is planning to appeal to the state government for compensation for the losses incurred.
