Diversification is an integral part of structural transformation of an economy. In brief it is the shift of work force either from one sector to another sector (Macro level diversification) or from one branch to other branch of a particular sector (Micro level diversification). So far as diversification within the agricultural sector is concerned it may be in terms of less profitable crop to high profitable crop i.e. crop to crop diversification or may be in terms of crop production to animal husbandry, fishing etc. i.e. crop to non-crop diversification. The present study mainly concentrates on crop-tocrop diversification in India for the period of 1980-81 to 2000-2001. Both food and nonfood crops have been considered here. The total period of discussion is subdivided into two sub-periods viz. pre reform period (1980-81 to 1989-90) and post reform period (1990- 91 to 2000-2001).
