French beans: what to measure and why
A high-value export crop with short cycles, strict residue limits and buyers who ask for records. Salt-sensitive, so irrigation water quality matters as much as quantity.
Growing conditions
The ranges french beans cares about
General agronomic ranges. A soil test and your agronomist decide the final numbers for your variety and site.
| Factor | Range | Note |
|---|---|---|
| Air temperature | 20–25 °C | Heat above ~30 °C causes flower drop |
| Soil pH | 6.0–7.0 | Typical target range |
| Salinity tolerance | sensitive (~1.0 dS/m) | Borehole water needs checking |
| Water | steady through flowering and pod fill | Stress gives short, curved pods |
Risks
Where french beans loses yield
Salty water
Beans are among the most salt-sensitive crops. EC in the water and the root zone should be watched, not assumed.
Residue rejection
Every spray has to be defensible. Automatic logs and toxicology records make that evidence routine.
