Seed drill is used to sow the seed

:$\implies$ Sowing is the act of dispersing the seeds in the soil for growing the plants. Before sowing the seed, selecting the good quality of the seeds is an essential task. The stable and good quality of the seed can be established by placing the seeds in the water. Good seeds sink in the water while damaged seeds float in the water because they are hollow from the inside and become lighter in weight. By this process, safe seeds can be distinguished from unhealthful or damaged seeds.

:$\implies$Manual sowing methods: Ancient people used this method because they had no equipment to sow the seeds. The seeds are picked up in the hands and slowly thrown or spread in the soil. This move is slow and the process takes time. But this is a cost-effective practice This method can only be used for a small area of land.

Sowing with the help of instruments: There are numerous types of tools that are used to sow seeds.
