In conditions of heavy, brown soil, in the Podkarpacki region, the effect
of the cultivation method (ridge cultivation, flat cultivation) and that
of irrigation on the yield, dry matter, soluble sugar, and carotenoid
content in carrots of Flacoro cultivar was evaluated. The total and
marketable yields (roots over 8 cm in length and diameter over 2.5 cm)
were estimated. In carrots grown on ridges an increase in the total yield
(by 0.2% in 1995 and by 14.1% in 1996-1997) as well as in the marketable
one (by 17.9% in 1995 and by 22.8% in 1996-1997) in comparison with that
in the case of flat cultivation was obtained. Irrigation of the carrots
significantly enhanced both total and marketable yields in relation to the
non-irrigated treatments, although this increase was significant only in
1995, which was a year with warm and dry summer months (July and August).
In that year a slight reduction in dry matter, soluble sugars, and
carotenoids was found in the roots harvested from ridges.
