Crop Production and Management-CBSE Class 8 Science
For healthy and quality crops, we need to sow the right quality seeds. In India, a government body called NSC (National Seeds Corporation) is involved in the production of good quality agricultural seeds. A large number of seed-testing laboratories are already set-up in different parts of the country.
Once the seeds have been selected, they need to be sown in the fields. “Sowing is the process of planting seeds in the soil”.
Precautions should be taken while sowing
- Seeds should be sown at an appropriate distance from one another. If the distance is not maintained, then the resources like air, sunlight and nutrient availability become an issue.
- The depth of sowing of seeds should be correct neither too deep nor shallow.
Methods of sowing
- Manual Sowing – Manual sowing is a sprinkling of seeds in the soil or we can dig the soil and bury the seed there. But this method is traditional and the major drawback is the seeds sown are unevenly distributed and the depth may not be appropriate.
- Seed Drill- A seed drill can be pulled across the field using bullocks or a tractor. The seed sown by this method are evenly distributed and placed at the correct depth in the soil.
