The local economy of Mahuva is primarily based on the agricultural produce market and industries. The Mahuva
Agricultural Produce Market Committee (APMC) was established in 1858. Mahuva and its surrounding villages produce onions. The Mahuva market yard is the second largest onion trading centre in India after
Lasalgaon, Maharashtra. It is famous for its good-quality red onions. Mahuva has the biggest onion market in Gujarat, so people also call it the onion capital of the state. It is spread across 38–40 acres of land. The region is the largest producer of
white onions and the second-largest producer of
red onions in the country. Onion is the largest trading commodity in Mahuva APMC. Mahuva is a large hub for onion processing and exporting, with over 120 large-scale
dehydration plants. Peanuts, cotton and coconuts are also major trading commodities, and
cotton ginning is conducted in the region.
