The economy of Assam is predominantly agrarian in nature having 28.11 lakh hectares of net cultivated area. In the study, Location coefficient (L), Simpson Diversity Index and CGR were used as analytical tools. In the state, net area sown, total cropped area and area sown more than once had increased. On the other hand, significant negative growth was recorded for forest area, barren and unculturable land, permanent pastures and other grazing land, land under miscellaneous trees, groves and fellow land. Higher concentrations of forest area, area sown more than once and lands put to non-agricultural purposes were reported in the state. Rice is the major crop in Assam accounting 60.87 per cent of the total cropped area during 2015-16. North Bank Plain Zone, Upper Brahmaputra Valley Zone and Hill Zone were reported to have higher crop diversification whereas, Central Brahmaputra Valley Zone, Lower Brahmaputra Valley Zone and Barak Valley Zone showed lower crop diversification.
