Prevention of stress on ground water can be made possible by way of recharging the ground water through scientific watershed management. Therefore, watershed treatment is an ideal method for recharging ground water and to prevent stress on ground water. In the present investigation, a modest attempt has been made to assess impact of watershed treatment on ground water recharge, crop productivity and socio-economic status of farmers in Malagi watershed in Hirekerur taluk, Haveri district, Karnataka. The water harvesting structures like check dam, farm pond, bore well recharge pit, earthen bunds and de-siltation of tanks and agro forestry were implemented. The nine bore well stations were randomly selected for taking ground water samples in upper, middle and lower reaches of the watershed. Out of 59 irrigation sources in the watershed, 25 sources were functioning and 34 sources were non-functioning before watershed treatment in which functioning irrigation sources were raised from 25 to 53 after watershed treatment. This clearly indicates that there is a net raise in the irrigation sources due to increase in the ground water recharge. Further, the maximum average bore well yield 2.50 L/ sec. was recorded in stations of lower reaches and minimum bore well yield 2.18 L/sec. in stations of upper reaches. It also resulted in an increase in the productivity of some crops such as sorghum from 2.7 to 3.4 q/acre, ground nut from 2.5 to 3.1 q/acre, maize from 3.5 to 3.9 q/acre, cotton from 2.9 to 3.2 q/acre and red gram from 1.8 to 2.3 q/acre, before and after watershed treatment, respectively. This shows that there is significant difference in the productivity of different crops before and after watershed treatment. The study indicated that about 26.66 per cent of the farmers were found to be socio economically strong, 53.33 per cent medium class and 20.00 per cent lower class in this watershed area.
