Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. Pump should supply pressure to the sprinklers system and the operating conditions must be designed to enable a uniform application of water.
Sprinkler irrigation divided to 4 major groups:
- Rain gun: mainly for field cop like maize, cotton, sugarcane, rice, etc.
- Impact Sprinkler: for establishment of vegetables after transplanting, large nurseries, growing “Green leaves cabbages lettuce etc.
- Mini Sprinklers and Foggers: especially for nurseries, plantation and as a cooling system.
- Center Pivot: using Mini sprinklers for Irrigation of large landscape.
Sprinkler irrigation advantages:
- Less interference with cultivation and less land loss.
- Higher application efficiency.
- High and frequent application can be effectively accomplished.
- Increasing humidity and lowing temperature (good for nurseries).
Sprinkler irrigation disadvantages:
- Poor uniformity and application efficiency in high wind regimes and / or dry and hot conditions Wind drift.
- Capital cost is high with greater operational costs due to higher
- Crops prone to diseases due to moist environment and wet foliar.
