Eu = Y/WR या सूत्राद्वारे ______ काढता येते.
उत्तर: प्रक्षेत्र पाणी वापर कार्यक्षमता (पर्याय 4)
महत्त्वाचे मुद्दे:
येथे, $Y$ = पिकाचे एकूण आर्थिक उत्पादन (Crop Yield) आणि $WR$ = शेतात पिकासाठी वापरलेले एकूण पाणी (Water Requirement / Water applied in field).
येथे उत्पादन आणि बाष्पोत्सर्जनाचे (ET) गुणोत्तर घेतले जाते.
Answer: Field water use efficiency (Option 4)
Key Points:
Where $Y$ is the economic crop yield and $WR$ is the total water requirement/water applied in the field.
Where yield is divided by total evapotranspiration ($ET$).
Field WUE includes water application losses and deep percolation in the field ($Y/WR$), whereas Crop WUE specifically considers consumptive evapotranspiration ($Y/ET$).
