The cultivation of Granadilla in Colombia, with its stable water needs, favors its production, which is why we optimize irrigation by probes.
Granadilla areas in Colombia, optimized by probes
The granadilla (Passiflora ligularis) is cultivated in areas with medium and cool-moderate climates:
Typical regions (with variations due to microclimate)
- Huila – Putumayo – Caquetá – Cauca – Nariño – Tolima – Cundinamarca – Antioquia – Boyacá.
- Common productive altitude ranges: 1,800 – 2,400 m above sea level
- It requires well-drained soil; it does not tolerate waterlogging.
WATER NEEDS
- It is not a "water-dependent" crop — it does not tolerate severe deficit during flowering/fruit set
- Requires stable moisture in the root zone (no dry-wet peaks)
Critical moments
- Flowering and fruit set → NO stress
- Fruit filling → deficit reduces size and quality
- Post-harvest → a slight deficit can be allowed for efficiency without penalizing vigor
Consumer guide idea (for design purposes, not for operating without probes)
- Drip/micro systems: typically 3–5 L/plant/day in adult stage during dry season (varies greatly depending on climate, density and Kc)
- With probes, irrigation is no longer based on a calendar, but on the actual condition of the soil
HOW TO OPTIMIZE PASSION FRUIT WITH PLANTAE PROBE
Location and quantity
- 3–4 stations/ha in a homogeneous plot; 6–8 if there is variability
- Para cada estación: 2–3 profundidades según perfil radicular:
- 20–25 cm (actividad principal)
- 40–45 cm (reserva / evitar déficit oculto)
- 60–70 cm si el suelo es profundo
Thresholds to configure in the Plantæ App (VWC indicative)
| Textura suelo | Inicio riego (alerta baja) | Cortar riego (alerta alta) |
|---|---|---|
| Sandy | 10–15 % | 18–22 % |
| Franc | 16–22 % | 24–28 % |
| clay loam | 22–30 % | 30–36 % |
Plantæ Operating Rule
Irrigate only if ≥2 depths of the station fall below the “low” threshold.
Stop when you return to the “high” band.
Phenological phase strategy
| Phase | Humidity policy |
|---|---|
| Flowering + fruit set | Keep within the mid-high range (do not allow it to reach the "bass") |
| Fill | Equal to curdled (without settling) |
| Between harvests | It can allow micro-deficits for conservation (a slightly lower threshold) without harming vigor |
