Explain the essential points that should be kept in mind while sowing the seeds.

Explanation

While sowing the seeds, following points need to be kept in mind:
(i) Seeds should be of good quality, healthy and free from diseases.
(ii) They must be planted at the proper depth in the soil. If planted deep in the soil, they cannot respire, and their shoots may not be able to push through the soil. If planted on the surface, they will be eaten by birds.
(iii) Seeds require water for germination. The soil should, therefore, have water in it. However, if there is too much water, seeds will not germinate properly.
(iv) Seeds should be sown at proper distances. If they are too close they will not get enough water, sunlight and nutrients. If they are too far apart, there is wastage of field space.
