Potato is one of the most important and widely cultivated vegetable crops of Assam and ranks fourth in terms of acreage under individual crop in the state. The present study features the agroclimatic-environment of potato zones of Assam developed on the basis of cumulative total frequency of area and productivity of potato. Data have been analysed since 1991-92 to 2015-16 in blocks of five years. Six potato zones were developed and analyzed for Assam. The analysis shows that zone-5 comprising of five districts has an average area and production of 1091.6 ha and 8220.1tonnes, respectively. The highest increase in area (61%) and production (64%) was recorded in the aforesaid zone. Area, production and productivity of potato in all the zones showed variation (i.e. increase or decrease) from 1991-92 to 2015-16. Zone wise highest contribution to area was found in zone 1 except for C (2001-02 to 06) and D (2006-07 to 11) block years. Similar trend was observed in production of potato apart from D block year.
