Onion farmers and marketers in Kano State have decried the effect of the blockade of food items to the southern part of the country, saying it is affecting them greatly.
Amalgamated Union of Foodstuff and Cattle Dealers of Nigeria (AUFCDN) had embarked on a strike, stopping food supplies to the South over attack on traders in Oyo.
This led to an increase in the price of food commodities in the south but in the north, the prices are plummeting and crashes.
Bags of onions that sold at N35,000 a few weeks ago are now selling for N7,000.
The ongoing strike by sellers of cows and foodstuff has however affected traders in the North as the price of food-stuffs dropped drastically.
Some Southern states, however, said they will invest heavily in agriculture to forestall such trend.
