Application of different mathematical functions to calculate growth coefficients GC and RGC of winter rape plants (Brassica napus L.)

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. Si...
