CULTURE REPORT
* Germination: Emergence at four
to six days with temperatures
at 65 to 70° F; lower the
temperature to 60 to 65° F after
emergence; cover seed
* EC (Electrical Conductivity):
Emergence to cotyledon
expansion = ~0.75 mS/cm;
Cotyledon expansion to plug
finish = ~1.0 mS/cm
* Plug Finish Time: four to five
weeks in 288 trays
* Transplant: Approximately 25 to
30 days after sowing, depending
on the temperature and cell tray
size, at three to four true leaf
stage. To prevent poor growth
later, do not transplant young
plants if the root is coiled.
If transplanted under high
temperatures, damage to roots
may occur. Dry soil will impede
proper root development.
* Young Plant Stage: Use welldrained
and sterile growing
media and keep good
ventilation to avoid stretching.
* Days to color: Approximately
90 days from sow to color
* Temperature: 65 to 75° F during
the day and below 55° F at night
for approximately two weeks
* EC: 2.0 to 3.5 mS/cm (pour
through method)
* pH: 5.7 to 6.4
PGR TREATMENTS
Effective PGRs include Cycocel at
1,500 ppm one time and Bonzi drench
2 to 5 ppm one time.
Earlier work with kale has shown
B-Nine, Cycocel or a combination
spray of the two products to be very
effective in controlling plant height.
However, B-Nine can suppress color
formation under certain conditions,
so it should be applied at the grower's
discretion. Alternatively, trials with the
Bonzi/Paczol (paclobutrazol) drench
have resulted in very effective
growth control and often enhance
color formation. Under cold spring
conditions, Bonzi rates of 2 to 5 ppm
will significantly reduce plant stretch.
Under warm fall conditions, the rates
may need to be increased to 8 to 10 ppm
for best results. Some PGRs can help
in color response, while others can
inhibit the desired colors.
