Pengalengan is the main potato production center in the Bandung district of Indonesia. About 76% of potato production of this district comes from Pengalengan, while contribution of Bandung to total production of West Java was about 60%. A significant reduction in the production in this subdistrict will have a great influence on potato supply in the region. Farmers at Pengalengan plant potato almost throughout the year. They divided the planting season into three seasons, i.e. Porekat (January–April), Ceboran (May–July) and Wuku (September–December). The area planted to potato in Ceboran is much lower than in other two seasons as it is the dry season and farmers normally use paddy fields or lands close to water sources or irrigation facilities. Farmers plant their dry lands with potato only in the Wuku and Porekat seasons. Thus planting dry lands commences after the onset of wet season (normally early September).
