The process of scattering seeds in the ground soil for growing the crop plants is called sowing.

The sowing of seeds with a seed drill has the following advantages:

(i) By using a seed drill for sowing, the seeds are sown at correct depth and correct intervals (or spacings).

(ii) The seeds sown with a seed drill are in regular rows.

(iii) When the seeds are sown in furrows by a seed drill, the seeds get covered by soil and hence these seeds cannot be picked up and eaten by birds. This prevents damage caused by birds.

(iv) Sowing by using a tractor-driven seed drill saves time and labour.
