While the core municipal area is urbanized, the immediate periphery of Dharmanagar relies heavily on agriculture. The fertile plains of the Juri River basin are ideal for cultivating rice, which is the staple crop of the region.
Cash crops play a massive role in the local agrarian economy, specifically rubber and tea. Tripura is India's second-largest natural rubber producer, and many plantations operate in the North Tripura district. Additionally, local farmers cultivate jackfruit, pineapples, betel leaf (paan), and bamboo. Inland fisheries in local ponds (pukhur) and small-scale poultry farming provide significant supplementary income and food security.
