How will the method of irrigation mentioned by you in (a) above help to conserve water?
Show Hint
Solution and Explanation
Unlike traditional surface irrigation methods, drip irrigation delivers water directly to the plant roots, reducing the surface area exposed to the air. This minimizes evaporation, which is a significant source of water loss in open irrigation systems, especially in hot climates.
Step 2: Precise water application.
Drip irrigation ensures that water is delivered only to the root zone of plants, reducing runoff and water wastage. This precise application ensures that plants receive just the right amount of water, avoiding over-irrigation and under-irrigation.
Step 3: Water savings.
This method can save up to 50% of the water compared to traditional irrigation methods, making it ideal for areas where water conservation is crucial. It ensures that water is used efficiently and effectively, reducing the need for additional water sources.
Step 4: Suitability for arid regions.
Drip irrigation is especially beneficial in arid and semi-arid regions, where water is scarce. The method is designed to maximize water use efficiency, making it suitable for large fields in such regions.

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
