Irrigation Efficiencies:
i) Water Conveyance Efficiency, (ηc)
where, Wf = Water delivered to the field
Wr = Water delivered from the reservoir
ii) Water Application Efficiency (ηa)
where, Ws = Water stored in the root zone
Wf = Water delivered to the field
iii) Water use Efficiency (ηu)
where, Wu = Water use consumptively.
Wf = Water delivered to the filed
iv) Water storage Efficiency (ηu)
where, Ws’ = Actual water stored in the root zone
Wf = Water needed to store to bring the water content up to field capacity.
v) Water distribution Efficiency, (ηd)
where, y = Average numerical deviation in the depth of water stored from the average depth of irrigation stored
d = Average depth during irrigation
vi) Consumptive use Efficiency (ηcu)
where, Wcu or Cu = Water used by plant consumptively.
Wd = Net amount of water depleted from root zone.

Efficiency of Water Storage
The ratio of the water stored in the root zone during irrigation, to the water needed in the root zone prior to irrigation is called the efficiency of water storage. It is a measure of how effectively the irrigation water is retained in the root zone for plant use.
Factors Affecting Efficiency of Water Storage
1. Soil Type: The type of soil in the root zone greatly affects the efficiency of water storage. Sandy soils have low water holding capacity and water is easily lost through percolation. Clay soils have high water holding capacity, but they are prone to waterlogging which can reduce plant growth.
2. Irrigation Method: The efficiency of water storage is influenced by the irrigation method used. Drip irrigation has a higher efficiency of water storage than flood irrigation.
3. Crop Type: Different crops have different water requirements and root depths. Crops with shallow roots require more frequent irrigation and have a lower efficiency of water storage.
Importance of Efficiency of Water Storage
Efficiency of water storage is an important factor in the overall efficiency of water use in agriculture. It helps to ensure that the water applied during irrigation is retained in the root zone for plant use. This can help to reduce water losses due to percolation and runoff, and increase crop yields.
Conclusion
Efficiency of water storage is the ratio of the water stored in the root zone during irrigation, to the water needed in the root zone prior to irrigation. It is influenced by soil type, irrigation method and crop type. It is an important factor in the overall efficiency of water use in agriculture.
