Frequently asked questions
How much water does drip irrigation save?
Drip typically uses 40-60% less water than flood irrigation for the same crop, because it delivers water directly to the root zone with almost no loss to evaporation or runoff. It also tends to raise yield through steadier root-zone moisture.
What does drip irrigation cost per acre?
Roughly 40,000-80,000 rupees per acre depending on crop spacing and layout, with trees needing fewer emitters than close-spaced vegetables. Against the water saved and yield gained, payback is usually one to two years, and subsidies may apply.
What maintenance does drip need?
Filter the water to stop emitters clogging with borewell sediment, match emitter flow and spacing to your soil type, and flush the lines periodically. A neglected system clogs and underperforms, so basic upkeep matters.
