Relations between technical equipment and human labour inputs were studied for selected family farms of Wojnicz rural district in Tarnów province. The objects examined by the inquiry were characterized in respect of labour consumption for assumed acreage intervals. Next, the statistical relationships were determined by using the STATISTICA v.5.0 programme. Exemplary diagrams of liner regression inserted in the paper present the influence of independent variables such as tractor power and average annual tractor utilization on the total labour inputs on the farms. On the basis of obtained results it was stated that increasing level of equipment with the technical means of production reduced labour inputs on the farms. However, the absolute quantity of consumed labour depended mostly on the labour inputs on animal production.
