(3) A and B

(4) C and D

The crops that have high Water Use Efficiency (WUE) are sorghum and pearl millet. The ratio of water used for plant metabolism to water lost through transpiration by plants is known as water use efficiency. It might be interpreted as an effort to decrease plant water loss by just delivering what is required.

Water-use efficiency, or WUE, is the proportion of water used by plants for metabolism to water lost by them through transpiration. Two categories of water-use efficiency are most frequently mentioned:

  • The ratio of biomass generated to the rate of transpiration is commonly used to quantify integrated water-use efficiency, also referred to as water-use efficiency of productivity.
  • The ratio of the rate of carbon assimilation to the ranspiration rate is known as the photosynthetic water-use efficiency, also referred to as the instantaneous water-use efficiency.

Summary:

Which of the following crops has high Water Use Efficiency (WUE)? (A) Pearl millet (B) Oat (C) Peas (D) Sorghum

The crops with the highest Water Use Efficiency (WUE) include sorghum and pearl millet. Water use efficiency is the proportion of water used by plants for metabolism to water lost through transpiration.
