Question

Write a paragraph in your own word on each of the following
(a) Preparation of soil
(c) Weeding
(d) threshing
(b) sowing​

Answer 1

Answer:

(a) Preparation of soil: The preparation of soil is the first step before growing a crop. One of the most important tasks in agriculture is to turn the soil and loosen it. This allows the roots to penetrate deep into the soil. The loosened soil helps in the growth of earthworms and microbes present in the soil.

(b) Sowing: Sowing is an important part of crop production. Before sowing, good quality, clean and healthy seeds of a good variety are selected. Farmers prefer to use seeds which give high yield. The process of putting seeds into the soil is called sowing. The tool used traditionally for sowing seeds is funnel-shaped. Nowadays a seed drill is used for sowing with the help of tractors. This tool sows the seeds uniformly at a proper distance and depth.

(c) Weeding: Some undesirable plants grow along with a crop. These unwanted plants are called weeds. The process of removing these unwanted plants is called weeding.

(d) Threshing: The process of separating grain seeds from the chaff is called threshing.

Answer 2

Answer:

(a) Preparation of soil

Preparation of soil is the first step before growing of crop. It helps to turn the soil and loosen it to allow the roots to penetrate deep into it. The loosening of the soil helps in the growth of several soil microbes, earthworms etc., which enrich the soil with humus and other essential nutrients. The process of turning and loosening is called ploughing. This is done using a plough, hoe and cultivators.

(b) Sowing

Sowing is the process of putting the seeds into the soil for growing crops. We need to use quality seeds for sowing. Sowing is done manually using mechanical equipment like Seed Drill. Seeds of few plants like rice are first grown in a separate area and then transplanted in the fields.

(c) Weeding

In a field many other undesirable plants may grow along with the crop. These undesirable plants are called weeds. Farmers use many ways to remove weeds. Methods to control weeds are: tilling before sowing of crops, physical removal of weeds by uprooting or cutting them close to the ground, using certain chemicals called weedicides etc.

(d) Threshing

Threshing is the process of separating grains or seeds from chaff. It is done after harvesting the crop. It is usually carried out with the help of a machine known as ‘Combine’. This machine is a combined harvester and thresher. It harvests plants as well as cleans grains.
