Micro Irrigation
Micro irrigation is defined as the methods in which low volume of water is applied at low pressure & high frequency usually an irrigation interval is in the ranges of 1 to 4 days. The system has extensive network of pipes at operated at low pressure. At pre-determined spacing outlets are provided for emission water generally known as emitters.
Drip irrigation:
In drip irrigation the required quantity of water is applied by means of mains, sub mains, manifolds & plastic laterals in the with equally spaced emitters usually laid on the ground surface at low pressure & at low discharge at the root zone of the crop.
Advantage of drip irrigation
-
Water saving is up to 40 to 60%
-
Enhance the plant growth & increases the crop yield

Improve efficiency of fertilizers.
-
Very flexible in operation
-
No soil erosion.
-
Easy installation, no land preparation.
-
Minimizing quantity of produce.
-
Enhances the maturity of the crop.
Limitations
-
