English हिन्दी
What will be the WUE ($\text{kg/ha/mm}$), if wheat crop used $40\text{ cm}$ of water during whole period and yielded $4.0\text{ t/ha}$ of grains?
यदि गेहूं की फसल ने पूरी अवधि के दौरान $40\text{ cm}$ पानी का उपयोग किया और $4.0\text{ t/ha}$ अनाज की उपज दी, तो जल उपयोग दक्षता ($\text{kg/ha/mm}$ में) क्या होगी?
EXPLANATION Crop Water Requirements, Water Use Efficiency (WUE), Consumptive Use and Irrigation Water Quality (SAR, RSC)

Calculation of crop Water Use Efficiency (WUE):

  • Formula: $\text{WUE} = \frac{\text{Economic Yield (kg/ha)}}{\text{Consumptive Water Use (mm)}}$
  • Yield: $4.0\text{ t/ha} = 4,000\text{ kg/ha}$
  • Water used: $40\text{ cm} = 400\text{ mm}$
  • $\text{WUE} = \frac{4,000\text{ kg/ha}}{400\text{ mm}} = 10\text{ kg/ha/mm}$.

जल उपयोग दक्षता (WUE) की गणना:

  • सूत्र: $\text{WUE} = \frac{\text{उपज (kg/ha)}}{\text{प्रयुक्त जल (mm)}}$
  • दाने की उपज = $4.0\text{ t/ha} = 4000\text{ kg/ha}$
  • प्रयुक्त जल की गहराई = $40\text{ cm} = 400\text{ mm}$
  • $\text{WUE} = \frac{4000}{400} = 10\text{ kg/ha/mm}$।
