Drought tolerance
This is the ability of agricultural crops to maintain growth and yield under conditions of soil moisture deficit and low air humidity.

Drought tolerance is a vital trait for crop resilience in regions prone to water stress. Selecting varieties with high tolerance levels helps farmers mitigate yield volatility during prolonged dry spells.
Practical management involves assessing plant traits such as root depth and cuticle thickness. Effective drought mitigation strategies also include soil management practices that enhance moisture retention, such as reduced tillage or cover cropping, to preserve subsoil water reserves.
A common error is over-relying on drought-tolerant varieties while ignoring the timing of irrigation. Even the most tolerant crops show a significant yield drop if water is scarce during their critical growth stages, such as flowering or grain filling.
