Standard carrot yield increased, when plant (r = 0.88)
and crop (r = 0.92) assimilation area and photosynthesis potential (correspondingly plant’s
photosynthesis potential r = 0.74, crop’s r = 0.91) increased, and the increasement of the net
photosynthesis productivity had negative (though not big) influence (plant’s photosynthesis
potential r = -0.4, crop’s r = -0.23) on productivity.
