Nagpur/ Mumbai / New Delhi/ Chandigarh, June 17 (ANI): Onion prices were increased across Maharashtra on Tuesday in wake of labourers' strike over a wage hike demand in the biggest wholesale market in Nashik city. The states of Maharashtra and Karnataka account for 45 per cent of onion produce in the country and if supplied from these two key states are hit, onion prices tend to spiral. The central government has asked the state government to sort out the issue. However, the northern Indian onion market remained untouched due to the timely arrival of crops from the neighbouring Rajasthan.
