1. Sow some seeds in the soil and arrange to water them by drip irrigation. Observe daily.
(i) Do you think it can save water?
(ii) Note the changes in the seed.
Answer:
The activity can be carried out as shown below:
Aim: To sow seeds, arrange to water them by drop irrigation and observe the changes daily.
Materials Required: Seeds, 1-liter plastic bottles, water, needle.
Procedure:
(i) Sow the seeds in the soil.
(ii) Prepare the drip system by poking holes near the bottom of the bottles using the nail.
(iii) Fill the bottles with water and place the bottles next to the seeds you want to water. Adjust the distance between the bottles based on how much water your seed might need. The setup is shown below:
Observations:
You will observe that gradually a seedling emerges from the seed and it grows into a new plant.
Conclusions:
We conclude that in drip irrigation, water is used more efficiently and less water is consumed. This is because water is delivered directly to the seed or roots of growing plants, which minimizes water wastage.
A real-world drip irrigation system is shown below:
