In a project where we <strong>in</strong>tend to augment the source <strong>of</strong> water, this<br />

<strong>in</strong>tervention facilitates the process by manag<strong>in</strong>g the demand prudently.<br />

Towards this, low <strong>in</strong>terest/zero percent bank loans or product subsidies<br />

should be provided to make it easier on the farmer’s pocket. The<br />

Government’s ‘Per Drop More Crop’ micro-irrigation scheme has to be<br />

put to use <strong>in</strong> the target area <strong>of</strong> river revitalization.<br />

A detailed note on the science <strong>of</strong> drip irrigation and its benefits <strong>in</strong><br />

comparison to flood irrigation with respect to water efficiency and yield<br />

can be found <strong>in</strong> Annexure 9.<br />

Accord<strong>in</strong>g to National Committee on Plasticulture Application <strong>in</strong><br />

Horticulture, it is observed that with micro-irrigation, there is an <strong>in</strong>crease<br />

<strong>in</strong> yield across various crops. Table 4 lists the effect <strong>of</strong> micro-irrigation on<br />

water usage and the yield improvement observed <strong>in</strong> many crops.<br />
