Cropping pattern, crop diversity and irrigation intensity of four water user categories i.e. own users (FUO), water sharing farmers (FShU), water selling farmers (FSeU) and water purchasing farmers (FPU) were analyzed in Chitradurga and Tumkuru districts of Karnataka. Institution of groundwater sharing and groundwater markets help farmers in making wise decisions regarding types and number of crops to be cultivated in a year and volume of groundwater to be applied. Modified entropy index (MEI) was used to analyze the crop diversification. Results have shown that, crop diversification is more in FShU farmers (0.92) as they allotted major proportion of land area (51.84 %) under field crops and was lowest in FPU farmers (0.82) as they have cultivated perennial crops in a larger area (62.57 %). Irrigation intensity was highest in FUO farmers’ category (88.44 %) and was lowest in FPU farmers category (70.83 %). Sharing of groundwater among siblings helped them to use available groundwater effectively and motivated them to incorporate diversity in their cropping system. FUO farmers were reluctant to take up more crops as they opined that, excessive crop diversification poses difficulties in management. FSeU farmers had less MEI value as preferred to save groundwater as they were also involved in groundwater selling
