Answer: D
It is the Transpiration ratio.
The transpiration ratio (water requirement in the physiological sense) is the number of units of water transpired by a plant to produce one unit of dry matter. Crops such as maize and sorghum, with C4 photosynthesis, have low ratios of about 250 to 350, while crops such as alfalfa have high ones.
Consumptive use is the total evapotranspiration of the crop plus water retained in the plant, not a ratio per unit dry matter. 'Physiological water requirement' and 'depth-internal yield data' are not the standard term.
