Total carrot root-crop yield increased, when plant
and crop assimilation area (correspondingly r = 0.82 and r = 0.81) and photosynthesis
potential (correspondingly r = 0.71 and 0.79) increased, and photosynthesis productivity
had slightly negative influence (correspondingly r = -0.44 and r = -0.11). The
increase of plant and crop assimilation area (correspondingly r = 0.88 and r = 0.92)
and photosynthesis potential (correspondingly r = 0.74 and r = 0.91) had strong
positive influence on the increase of marketable yield; the increase of plant and crop
photosynthesis productivity had small negative influence (correspondingly r = -0.54
and r = -0.23).
