Question

The heavier seeds are sown in the soil by two ways​

Answer 1

Answer:

The tools we use for ploughing are:

Plough: This is the most ancient tool used for ploughing. A plough may be made of wood or a metal such as iron. It has a blade or sticks attached to the front that is used to cut through the soil. Ploughs are traditionally drawn by cattle such as ox or cows, but in modern times tractors are used. Ploughs till the soil, add manure and fertilizers and scrapes the soil.

Hoe: A hoe is also an ancient agricultural tool. We use it to till the land, remove weeds and dig up soil. They generally have a long wooden rod with a bent iron plate at one end. The other end may be attached to an animal. Hoe was used for tilling in olden times, but these days are only used to remove weeds.

Cultivator: This is the modern mechanism we use currently to plough our farms. It involves the use of a tractor to drive the cultivator. They dig up and pulverize the soil. Cultivators also kill weeds and dig up unwanted vegetation. Cultivator may be more expensive than the traditional methods, but it saves a lot of time and labour force.

Answer 2

Explanation:

Sowing of seeds

This is the second step in crop production. Once the soil preparation is done, it is now time to sow the seeds. Sowing is the actual process of planting the seeds in the soil. The seeds that are sown have to be selected very carefully and have to of high quality.

Methods of sowing seeds

The various methods of sowing the seeds are

1) Sowing by hand: The scattering of seeds by hand is the simplest method of sowing seeds. This method is also called broadcasting. This is the most economical method that can be employed. However the distribution of seeds is not uniform, it may result in clusters of seeds on the field.

2) Seed Drill: This is a modern method of sowing seeds. It is better and more efficient method than sowing by hand. It is usually done by attaching iron drills to a tractor. Seed drills ensure that the seeds are planted at equal intervals and at the correct depth in the soil.

Precautions to be taken while sowing seeds

Sowing seeds is essentially the most important part of crop production. It is necessary to focus on even the smallest details. The following precautions should be taken when sowing seeds,

• Seeds must be planted at the correct distance or intervals from each other. This is to ensure that all plants get their fair share of light, water and nutrients for growth and development. Planting seeds at equidistance have been proved to increase the yield of the farm.
• Seeds must be sown at the correct depth in the soil. If seeds are simply scattered on the top they are likely to be blown away or eaten by animals or birds. If we sow them too deep into the ground, they will not germinate due to lack of air.
• The seeds that you sow should be of the highest quality. They have to germ and disease free
