In economics, yield is a measure of the amount of income an investment generates over time (related to return on investment). For example, farmers talk of the yield per unit area of land.
In semiconductor device fabrication, yield is the ratio of functionally working devices and the total number of devices produced.
In the context of nuclear weapons, the yield of a weapon is the amount of energy discharged when the weapon explodes, commonly expressed in tons of trinitrotoluene (TNT) needed to produce the same energy.
In road transport, a yield (American English) or give way (Commonwealth English) traffic sign indicates that a driver of a vehicle must slow down and prepare to stop if necessary (usually while merging into traffic on another road) but does not need to stop if there is no reason to. A driver who has actually stopped in this situation is said to have yielded the right-of-way to through traffic on the main road. In contrast, a stop sign always requires a full stop.
