Net Irrigation Requirement (N!R) is the amount of irrigation water required in order to meet the evapotranspiration need of the crop as well another, needs such as leaching. Therefore, NIR = Cu - Re + Water lost as percolation in satisfying other needs such as teaching.

Net Irrigation Requirement Calculation
The net irrigation requirement of a crop is the amount of water required by the crop to grow and mature. It is calculated by subtracting the effective rainfall, leaching, and other losses from the consumptive use of the crop.
Consumptive Use
Consumptive use is the amount of water used by the crop for transpiration and evaporation. It is the sum of the water used by the crop through the leaves (transpiration) and the water lost to the atmosphere from the soil surface (evaporation).
Effective Rainfall
Effective rainfall is the amount of rainfall that is stored in the soil and is available for the plant to use. It is calculated by subtracting the losses due to runoff and deep percolation from the total rainfall.
Leaching and Other Requirements
Leaching is the process of flushing out the excess salts from the soil by applying water. Other requirements include the water required for soil preparation, irrigation system losses, and other miscellaneous losses.
Net Irrigation Requirement Calculation
The net irrigation requirement of a crop is calculated by subtracting the effective rainfall, leaching, and other requirements from the consumptive use of the crop. Therefore, the correct option is C, i.e., net irrigation requirement = consumptive use - effective rainfall - leaching and other requirements.
In conclusion, calculating the net irrigation requirement of a crop is essential in determining the amount of water required for the crop to grow and mature. The calculation involves various factors such as consumptive use, effective rainfall, leaching, and other requirements.
