Present study was carried out across different Agro-climatic zones of Karnataka to assess the extent of agricultural diversification in the state. the study spans over a period of 20 years from 1992 to 2012 was divided into two phases (1992 to 2002 and 2002 to 2012) to assess the impact of agricultural policy on Karnataka agriculture as a whole and cropping pattern in particular, Studies indicated complete decadal shift in cropping pattern in North Eastern Transition Zone (0.1514 & 0.1274), North Eastern Dry Zone (0.1588 & 0.1464), Central Dry Zone (0.1666 & 0.1593), Southern Dry Zone (0.1748 & 0.1770), Southern Transition Zone (0.1754 & 0.1649) and Northern Transition Zone (0.1542 & 0.1254). Whereas the extent of diversification was more during first decade in the above mentioned zones, Hilly Zone and Coastal Zone (0.6733 & 0.6973) indicated crop specialization. Eastern Dry Zone (0.3758 & 0.3680) revealed moderate diversification in cropping pattern for both the decades.
