Multistage random sampling technique was employed to select 144 sample farmers from 12 selected tank commands primary data was collected by personnel interview method. Tabular and production function analyses were employed to analyze the data. The study identified, two major farming systems each in Bagalkot and Koppal districts and three in Haveri district. In each district dairy enterprise was found to be most common as a complementary enterprise. Farming System-I of Koppal district exhibited by highest net returns (Rs.35,645/ha) followed by Farming System-I of Bagalkot district (Rs.31,238/ha). Production function analysis revealed that, inputs such as labour, seeds, fertilizers + FYM and PPG + veterinary charges were under utilized in Bagalkot district. The resources like labour, feed and concentrates and seeds were under utilized in Koppal and Haveri districts. Hence, there is scope for deployment of these resources. In OFD and FFS plots returns were increased over control plots due to reduced cost of cultivation and increased yield. The OFD/FFS conducted have successfully communicated the information on modern crop production technology to farming community. Constraints like non-availability of quality seeds, lack of awareness of recommended cropping sequences, high cost of inputs, lack of credit facility, scarcity of owned funds, low price for the produce and lack of storage facility were most severe in crop production. Hence, there is need to strengthen institutional support for provision of credit, infrastructure facility and formulate appropriate policies for safe guarding the interest of the farmers.ennullThesis
