Water use efficiency
A metric representing the amount of water required by a crop to produce a unit of dry biomass.
Также говорят: transpiration ratio, water consumption coefficient
Water use efficiency (WUE) is a fundamental agronomic parameter used to evaluate how effectively crops convert water into harvestable yield. It serves as a basis for irrigation scheduling and resource management strategies.
Producers utilize this metric to minimize irrigation inputs and adapt farming practices to local climate volatility. Key factors influencing WUE include crop genetics, soil moisture retention capacity, and tillage systems.
A common mistake is failing to account for soil evaporation, which leads to inaccurate water budget calculations. Additionally, over-fertilization can sometimes distort the expected efficiency, highlighting the need for a holistic approach to crop management.
