The methodology of calculation of new coefficients, characterizing dry matter accumulation is presented. Eight representative mathematical functions were used and the data referring to the increase of dry matter of winter rape plants (Brassica napus L.) during the spring-summer vegetation season. Significance of the applied growth models was verified by using statistical parametrical tests. As a result of the analytical or numerical integration, the growth coefficient (GC) and the relative growth coefficient (RGC) were determined for each function. They describe plant growth potential and mean plant dry matter values during the vegetation season respectively. Depending on the type of the mathematical function the growth coefficient (GC) oscillated within the limits from 1564 g day to 1637 g day, and the relative growth coefficient (RGC) values ranged from 18.8 to 19.7 g
