Answer 1

Hint: Plough is a farming tool that turns the soil before planting the crops and is most commonly used. It helps in the sowing of the seeds long before and is said to be a primitive tool due to its use during history.

Complete answer:
The agricultural use of plough is churning the soil up and down. The plough helps the soil to get an even texture by mixing it thoroughly. The soil earlier becomes uneven due to getting rough and dry depending upon the various climatic conditions. The soil when solidified can also be broken with the help of plough. The mixing of the soil done by the plough will help the soil to make space for the growing of the seed. The oxen or the tractors are attached to the plough and they help them pull it throughout the ground. Thus its working efficiency per day is found to be 0.4 ha.

Additional information:
1. Plough is a large fork-like structure that is pulled up and around with the help of a cow, bull, or a tractor.
2. Ploughs help the soil in turning up the topsoil and the lower soil that results in the increase of the aeration in the soil.
3. The capacity of the water retention can also be increased in the soil with the help of the plough.
4. The weeds or the unnecessary plants can be eradicated through plough and thus are found to be useful for farmers.
5.The weeds need to be removed since they compete with other plants for food, nutrition, shelter, and other resources of the field. They need to be removed from their roots which can be done by using plough.

So, the correct answer is ‘0.4 ha’.

Note:
It is an important tool used for the cultivation of plants and for the removal of weeds.
The mixing of various fertilizers and pesticides can be done even in the soil with the help of the plough. From the German word huohili, the English term plough was derived that means ‘scratch plough'. Home farming was thought to be the best way of farming during the ancient times.
