When the availability of water is poor, drip irrigation system is used. In this the water reaches the plant drop by drop through sprinklers. So that water comes out from the sprinklers wetting exactly the place of the roots of the plant.
Advantages:
1. Maximum use of available water.
2. No water being available to weeds.
3. Maximum crop yield.
4. Efficiency use of fertilizers.
5. Less weed growth.
6. Low labour and low operation cost.
7. No soil erosion.
8. Improved infiltration in soil with low in take.
Disadvantages:
1. Sensitivity to clogging.
2. Moisture distribution problem.
3. Salinity hazards
4. High cost compared to furrow.
5. High skills is required for design, install and operation.
