The Leningrad region in Russia has emerged as a leading producer of cultivated mushrooms, accounting for 6.1% of the country's total production in 2020 with 5.3 thousand tons of champignons. This represents a threefold increase from 2019, attributed to the commencement of a new greenhouse complex at Vyborzhets agricultural company. Covering 3.9 hectares, the complex can produce up to 10 thousand tons of champignons annually. The region's growth in mushroom production has been bolstered by financial support for protected soil enterprises. In 2020, these enterprises received 77.3 million rubles in state financial aid.
