ETc stands for which irrigation term?

Explanation:
ETc refers to what the crop actually loses in water through both soil evaporation and plant transpiration over a specific period. It represents the crop’s real evapotranspiration under current conditions, and is typically calculated by multiplying the reference evapotranspiration (ET0) by a crop coefficient (Kc): ETc = ET0 × Kc. This reflects how different crops and growth stages use water. The other terms aren’t the standard name for this concept. An evapotranspiration coefficient would be the Kc used to adjust ET0, not the ETc itself; environmental temperature coefficient and evaporation total complement aren’t established terms for this purpose.
