Micro Irrigation |
 |
Why Micro Irrigation is necessary? |
| |
| • |
To improve the productivity of irrigated land from the present low levels. |
| • |
To improve use-efficiencies of Water, Energy, Nutrient and Human Effort in Agriculture. |
| • |
To conserve scarce resources such as Water and Electricity. |
| • |
To extend the benefits of irrigated agriculture to more people with the available water. |
| • |
To facilitate better crop management through Fertigation and Chemigation. |
|
| |
|
|
Principles of Micro Irrigation? |
| |
| • |
Water is applied directly to the root zone of the plants. |
| • |
Water is applied at frequent intervals at precise quantities based on Crop Water Requirements. |
| • |
Water is applied through a low-pressure pipe network comprising Mains, Submains, Laterals and Emitting Devices |

Advantages of Micro Irrigation |
| |
• Crop Yield Enhancement
• Saving in Irrigation Water
• Saving in Energy in pumping
• Savings in Fertilizer consumption
• Quality Improvement of Produce
• Improved Pest & Disease Control
• Improves Soil Health
• Reduced Weed Growth
• Reduced Labor Costs
• Suitable for Marginal lands
• Suitable for inferior quality water |
| |
|
|
Tailor- made |
| |
Micro Irrigation Systems need to be tailor- made, (Because, any or all of the following are different in different fields) :
• Field Size and Shape
• Field Undulations
• Crops and Planting Patterns
• Water Quality issues
• Yield from Water Sources
• Location of water sources
• Soil Types
• Crop rotations
• No. of hours of electricity availability
• No. of hours of labour availability
• Climatological variations
• Multiple cropping situations
• Quality of Farm Management |

| Crop |
Crop Spacing |
Adjustable Micro Irrigation System |
| Horticulture Crop |
12 m to 3 m between crop raw. (wide spaced) |
Drip Irrigation System / Pours Pipe |
| Crops fruit part under ground like Potato, Groundnut, Turmeric, Ginger, Vegetables, Medicinal Crops etc. |
Less then 1 m between crop raw. (Narrow) |
Drip Irrigation / Sprinkler Irrigation / Raingun |
| Field Crops like Cotton, Castor, Tobacco, Pulses, Sugarcane, Banana, Vegetables etc. |
Less then 3 m between two crops |
Drip Irrigation |
| Fodder Crops / Nursery Raising of Vegetables, Ornamental Crops etc. |
