_____ या संज्ञेत वनस्पती पिकांच्या चयापचय क्रियेत वापरल्या जाणाऱ्या पाण्याचाही वापर गृहित धरला जातो.
EN
The term _____ also takes into account the water used in the metabolic activities of crop plants along with evapotranspiration.
उत्तर: उपभोग्य पाणी वापर (पर्याय 3)
महत्त्वाचे मुद्दे:
•
उपभोग्य पाणी वापर (Consumptive Use - Cu): वनस्पतीद्वारे बाष्पोत्सर्जन (Transpiration), जमिनीच्या पृष्ठभागावरून होणारे बाष्पीभवन (Evaporation), आणि वनस्पतींच्या वनस्पती चयापचय क्रियांमध्ये (Metabolic activities) वापरल्या जाणाऱ्या पाण्याचा एकत्रित समावेश उपभोग्य पाण्यात होतो.
•
चयापचय क्रियांमध्ये लागणारे पाणी एकूण वापराच्या १% पेक्षा कमी असल्याने बऱ्याचदा उपभोग्य वापर आणि बाष्पोत्सर्जन (ET) समान मानले जातात.

English Explanation / स्पष्टीकरण:
Answer: Consumptive water use (Option 3)
Key Points:
•
Consumptive Use (Cu): Refers to the total sum of water transpired by the crop, water evaporated from the adjacent soil surface, and the small amount of water retained and utilized in plant metabolic activities.
•
Since the metabolic water is very small (usually <1%), consumptive use is practically treated as equivalent to evapotranspiration (ET).
