Agriculture plays a predominant role in Indian economy and contributes 18 per cent to India’s gross domestic product. Farmers have to take series of decisions to make farming a viable enterprise. A study was planned to know the decision making behaviour and its influence on the socio economic performance of farm households. The respondents were chosen from three districts viz. Raichur, Gulbarga and Koppal. Thirty farmers from rainfed situation and thirty farmers from irrigated situation were chosen from each district making a total sample size of 180. The results revealed that Number of family members, achievement motivation score and decision making behaviour score were found to be significantly influencing the annual agricultural income. As the decision making behaviour score increases by one unit the annual agricultural income increases by Rs . Type of risk behaviour was not significant implying that whether farmers were risk loving, risk averse or risk neutral did not influence the annual agricultural income significantly. Irrigated rainfed dummy, number of years of schooling, achievement motivation score, risk orientation score and mass media participation were found to be significantly influencing the institutional participation. Number of family members and decision making behaviour score were found to be significantly influencing the total annual income. | Decision making behaviour and its influence on the socio economic performance of farm households in H-K Region of Karnataka, India
