When assimilation area increased in the periods of early growth (from sowing
up to 6–10 leaves) and intensive leaf growth periods, the amounts of dry matter also
increased (r = 0.99 ir r = 0.97), and before the yield gathering, when leaf assimilation
area decreased, the amounts of dry matter also decreased (r = -0.64), but increased
carrot yield: assimilation area influenced the increase of total yield 31 % (r = 0.82),
the increase of the standard one – 32 % (r = 0.88)
