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.
