Campana

CROP TIME

Production begins 10 - 11 weeks after planting. Harvest lasts 3 weeks.

STEM HEIGHT

76 cm

PLANTING DENSITY

64 plants /m2 net or 6 plants/ft2

PRE-PLANTING

Soil: Well drained, loose soil with no clusters, at least 25 cm (10 in) deep.

PH: 5.5 to 6.5

Netting: 2 levels.

ADDITIONAL LIGHT

Start 7 days after planting for 45 days.  Vegetative growth and floral induction are achieved with long day condition. 

There after flower development responds better with short day condition.  The critical long day photoperiod is 14 hours, although 16 hrs work better.   Light can be continuous or by pulse up to 4 hrs at night.  10  Footcandle or 110 Lux is required.

PINCH

Week 9 to 10 (to even up the spray).

IRRIGATION

Apply an average daily volume  of 5 to 5.5l/m2/day according to the soil’s humidity evapotranspiration conditions and the organoleptic evaluation.

Excess irrigation can cause pathogens  development and physiological desiquilibrium.

FERTILIZATION

Excess of nitrogen can cause the plants to be susceptible to Botrytis.  A general formula can be the following:

N: 120 ppm , P: 50 ppm, K: 150 ppm

Ca: 120 ppm, Mg: 50 ppm, S: 50 ppm

Fe: 1 ppm, Mn: 1.2 ppm, Cu,: 0.40 ppm

Zn: 1.20 ppm, B: 0.25 ppm.

HARVEST

Haverst when the flowers start showing color at the ends  and once the petals start speading out.

POSTHARVEST TREATMENT

Hydrate in AVB (0.5 cm3 /Lt de Agua + AVB Booster (1 cm3/Lt)  for 4 hours.  Then hydrate in CHRYSAL PROFESSIONAL 2 (10 cm3/Lt) x 4 hours.
