Which of the following is/are the advantage /advantages of practising drip irrigation?

1. Reduction in weed
2. Reduction in soil salinity
3. Reduction in soil erosion

Select the correct answer using the code given below.

Drip irrigation offers several advantages related to weed control and soil erosion.

Statement 1: Reduction in weed Drip irrigation delivers water directly to the plant roots, minimizing moisture availability in the areas between rows. This inhibits weed growth because weeds are deprived of readily available water. Statement 1 is correct.

Statement 2: Reduction in soil salinity While drip irrigation can help manage salinity in waterlogged areas by reducing overall water usage, it doesn't inherently guarantee a reduction in soil salinity in all cases. The relationship between drip irrigation and soil salinity is complex and depends on various factors. Therefore, a general claim of salinity reduction isn't accurate. Statement 2 is not correct.

Statement 3: Reduction in soil erosion Unlike surface irrigation, which can cause significant soil erosion due to rapid water flow, drip irrigation delivers water slowly and directly to the roots. This significantly minimizes soil erosion. Statement 3 is correct.

Hence, only statements 1 and 3 are correct.
