The correct option is (c).
Explanation
The Seed Drill is a modern agricultural implement used for sowing seeds, typically operated with the help of a tractor. It is designed to improve the efficiency and precision of the sowing process compared to traditional manual methods.
Statement-wise Analysis:
- Statement 1 is Correct: The primary advantage of a seed drill is that it sows seeds uniformly at equal distances and depths. This precision prevents overcrowding of plants and ensures that each seed has access to sufficient soil moisture, sunlight, and nutrients.
- Statement 2 is Incorrect: A seed drill is a mechanized tool where seeds are placed in a hopper and distributed automatically through tubes. It does not require manual placement of seeds into the soil; manual placement is characteristic of traditional methods like broadcasting or dibbling.
- Statement 3 is Correct: The use of a seed drill significantly saves time and labour. It allows for rapid sowing over large areas and simultaneously covers the seeds with soil, which protects them from being eaten by birds.
Key Takeaway:
The Seed Drill ensures uniform sowing depth and spacing, which is essential for optimal crop growth, while drastically reducing the manual labour and time associated with traditional agricultural practices.
