CONCLUSIONS:
|
1.
|
|
Carrots can be grown in flowing hydroponic culture, but the
percentage of split and forked roots was higher than in soil-less
media.
|
2.
|
|
The percentage of split and forked roots can be minimized by
cultivar selection.
|
3.
|
|
Carrots can be grown under HPS lamps.
|
4.
|
|
Root shape was more typical in soil-less media than in
hydroponics. Many hydroponic roots had a large top diameters with
long thin tails.
|
5.
|
|
The orange color intensity was better in soil-less media than in
hydroponics.
|
6.
|
|
It is essential to minimize light leakage around the stem base to
eliminate chlorophyll formation in the tops of the storage roots
in hydroponics.
|
7.
|
|
Growth of the tops was overly vigorous. Height was 40 to 55 cm,
which is taller than field grown carrots. Reducing nitrogen in the
root-zone may reduce top growth and increase harvest index.
|
8.
|
|
The best cultivars were:
1. Scarlett Nantes: Best yield
and shape in both types of media.
2. Sweetness & Red Core Chantenay: good yields but atypical
root shape.
