The correct answer is: d) All of the above.

Micro-irrigation techniques like drip and sprinklers are promoted by the Punjab government to conserve water, improve water use efficiency, and increase crop yields.

• Conserving water: Micro-irrigation techniques deliver water directly to the roots of plants, which reduces evaporation and runoff. This can save up to 50% of water compared to traditional irrigation methods.
• Improving water use efficiency: Micro-irrigation techniques also improve water use efficiency by delivering water more precisely to plants. This means that less water is wasted, and more water is available for crops.
• Increasing crop yields: Micro-irrigation techniques can also increase crop yields by providing plants with the water they need when they need it. This can lead to healthier plants and higher yields.

In addition to these benefits, micro-irrigation techniques can also reduce the risk of soil erosion and improve the quality of water. They can also be used to irrigate crops in areas where traditional irrigation methods are not feasible, such as on steep slopes or in areas with limited water resources.
