Abstract
In 1949-2010, the draft force resources in Polish agriculture increased by 420.6%. At the same time, there was more than eightfold increase in mechanical draft force and reduction in live one by 90%. In 2010, the value of gross output in constant prices was higher than in 1949 by 113.2%, final output – by 186.7% and market output – by 370.9%. It was noted that there is a positive correlation between equipment in the draft force and the value of agricultural production. Its strength, when considering only the mechanical draft force, was higher as compared to the total draft force taken into account. The correlation is the strongest when the market output is taken as a measure of agricultural production and the weakest for the gross output. The correlation is the strongest when the market output is taken as a measure of agricultural production and the weakest for the gross output.
