Farmers in the Mekong Delta are facing high fertilizer prices and are therefore switching to organic fertilizers like cow manure for Thai jackfruit trees. Mr. Nguyen Van Binh explains that cow dung helps the trees grow well and resist diseases, producing heavier and sweeter fruit. However, fresh cow manure should not be used as it contains pathogens and acidic substances. The cost of dried cow dung is only about 20,000 VND/bag (50kg), making it a more economical option for farmers. Despite the benefits, the price of Thai jackfruit is currently low and there is no sign of an increase in the near future.
