The Study was conducted in Eastern dry zone of  Karnataka consisting of three districts. From each district, one taluk was purposively selected. From each of the so selected taluks, four villages were randomly chosen. Totally, 12 villages were considered for the study based on the farmers pursuing farming systems i.e., Crop, Crop + dairy, Crop + dairy + sericulture and Crop + sericulture and Crop + sericulture farming systems. Thirty respondents were selected on probability proportion under each of the four selected farming systems. Thus, 120 respondents were selected for the study. The findings revealed that majority of the respondents were middle aged, had medium education level, marginal farmers, with low social participation, medium livestock possession, low cosmopoliteness, low management orientation, medium level of scientific orientation, medium level of risk willingness, and medium innovativeness. The extension use efficiency was found high in crop + dairy + sericulture farming system followed by crop + sericulture, crop + dairy and crop production. The results about the regression values of all the 12 variables against the extension use efficiency in the selected farming systems revealed that under the crop production farming system, cosmopoliteness was found to be significant at 1 per cent level. While landholding, cropping intensity and scientific orientation were found to be significant at 5 per cent level. Under crop + dairy farming system, landholding was found to be significant at 1 per cent level while livestock possession cosmopoliteness and scientific orientation at 5 per cent level while  crop + dairy + sericulture farming system, family size, social participation and cropping intensity were found to be significant at 5 per cent level. Education was found to be significant at 1 per cent level while Cosmopoliteness,  management orientation and cropping intensity were significant  at 5 per cent level under crop + sericulture farming system.
