Micro irrigation systems deliver water directly to the root zone of crops in small, controlled amounts. This method helps farmers save water and increase crop yields. The system includes pipes, filters, valves, drippers, emitters, and micro sprinklers. It is widely used for fruit, vegetables, flowers, orchards, nurseries, sugarcane, cotton, and plantation crops.

Micro Irrigation in Indian Farming

India uses a large portion of its available freshwater for agriculture. Micro irrigation is promoted to address water scarcity and improve efficiency. The government supports this through the “Per Drop More Crop” initiative. This program aims to enhance water-use efficiency at the farm level.

Farmers can use various water sources such as borewells, ponds, tanks, canals, or farm reservoirs. Water is pumped into a main pipeline, where filters remove sand, mud, and small particles. The filtered water then travels through sub-main and lateral pipes. Drippers or micro sprinklers release water near the plant roots.

System Operation and Benefits

Micro irrigation systems can also deliver fertilizers with water, a process called fertigation. This method reduces fertilizer loss and provides nutrients directly to crops. Using micro irrigation can cut deep water loss, runoff, and evaporation by up to 40%. It also reduces the time needed for pumping, saving electricity or diesel.

Consistent watering near the roots supports better crop growth. The system helps control weeds and conserves fertilizer by making it soluble and easy to apply. Farmers can irrigate more land with limited water resources. However, the initial investment can be high for small and marginal farmers.

Maintenance and Challenges

Regular maintenance is necessary for optimal performance. Filters, drippers, and pipes must be cleaned often. Drippers may become blocked if the water contains mud, salts, or algae. Farmers need training to manage pressure, spacing, fertigation, and cleaning schedules.

The quality of design and materials affects the system’s lifespan and effectiveness. Certified equipment and trained installers are recommended for best results. Proper installation and maintenance ensure the system delivers its full benefits to crops.
