Correct option is because seed drill is a machine which sow seed with equal distance between them and also in specific depth so that the birds don't harm it . Seed drill saves labour and time

Seed drill is used to sow the seeds.

Seed drill is an agricultural implement that is used to sow seeds uniformly and at a specific depth in the soil. It is an important tool in modern farming as it helps in increasing the efficiency and productivity of the sowing process.

Benefits of using a seed drill:

1. Uniform sowing: One of the main advantages of using a seed drill is that it ensures uniform sowing of seeds. The machine is equipped with mechanisms that regulate the distance between seeds and the depth at which they are sown. This helps in achieving even distribution of seeds, which is essential for proper growth and development of crops.

2. Time-saving: By using a seed drill, farmers can sow seeds in a much quicker and efficient manner compared to traditional methods. The machine is capable of sowing a large area of land in a relatively short period of time, thereby saving labor and time.

3. Optimal seed placement: Seed drills are designed in such a way that they place the seeds at the ideal depth in the soil. This ensures that the seeds receive adequate moisture, nutrients, and protection from external factors like wind and birds. Proper seed placement is crucial for the germination and establishment of crops.

4. Reduced seed wastage: Seed drills help in reducing seed wastage by accurately placing the seeds at the desired spacing. This prevents overcrowding of plants and allows them to grow without competition for resources. Additionally, the machine also prevents seed loss due to birds and other pests.

5. Improved crop yield: The use of a seed drill can lead to higher crop yields as it provides optimal conditions for seed germination and growth. Uniform sowing, proper seed placement, and reduced seed wastage contribute to the overall productivity of the crops.

In conclusion, a seed drill is an agricultural implement that is used to sow seeds in a uniform and efficient manner. It offers several benefits such as uniform sowing, time-saving, optimal seed placement, reduced seed wastage, and improved crop yield.
