Answer 1

Answer:

Hi friend

This is your answer

Explanation:

(a) Preparation of soil:It is the first method to be followed before growing a crop. This method is usually employed for loosening the soil to allow the root 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. Plants require nutrients for their proper growth and functioning. The process of loosening is called tilling or ploughing the soil. Tilling of soil brings the nutrient-rich soil to the top. This helps the plants to utilize the nutrients for their growth.(b)Sowing:Sowing is another important step in crop production. It is the process of placing the seed in or on the soil for future growth. The seeds that are selected for growing should be of good quality. This will improve the net yield of the crop. Sowing is usually done with the help of either a traditional tool or a seed drill. The traditional tool is shaped like a funnel. It was used earlier for sowing seeds. Nowadays, seed drills that make the use of tractors are used for sowing seeds. This tool disperses seeds uniformly and sows seeds at proper depth. Sowing by this method saves time and also protects the seeds from birds.(c)Weeding:Undesirable plants that grow along with the crop are known as weeds. Weeding is the process of removing these weeds. Xanthium, Parthenium, etc. are some common weeds. Weeds compete with the crop for nutrients, light, and space. As a result, crop plants get lesser nutrients, light, and space for their development. This in turn, reduces their productivity. Thus, various weeding methods are employed.Some important weeding methods are:(i) Weeds can be controlled using weedicides. It is a chemical, which is sprayed in the fields to kill all available weeds. Weedicides are not harmful to crops.(ii) Tilling before sowing of crops also helps in removing weeds. Tilling uproots the weeds. The best time for removal of weeds is before they produce flowers and seeds.(iii) The manual method of removing weeds is with the help of a khurpi. It involves regular uprooting or cutting of weeds close to the ground.(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.

Answer 2

Question:

Write a paragraph on , Preparation of soil , sowing , weeding , threshing

Answer:

i) Preparation of soil is the first step during agricultural practices . It is very important to prepare the soil by loosening it before the growing crops. That allows the plant roots to grow deep into the soil during crop production. The loosening of soil help earthworms and microbes to grow in the soil. The top layer of soil supports the plants to grow fast. so loosening of soil help the soil nutrients to come to the top of the soil.

ii) Sowing means to spreading the seeds in the soil. Before sowing we need to separate good quality of seeds. Sowing is generally done by a mechanical machine called seed drill..

iii) including the crop some other plants also grown in the fields. These are called weeds. some time weeds are harmful after harvesting maybe it will cause disease and decreases immunity power in both human and animals. also it can fight with crop to get water and nutrients. so that crops can't get the right quantity of water and nutrients. so we need to remove the weeds from the field. this is the process of removing weeds is called weeding. wedding is done manually by the equipment called as KHURPI..

iv) harvesting the seeds manually done by sickle or by harvester. the harvested crop grain needs to be separated from the Chaff. this process of separating chaffs from the grains is called threshing. this is done by the machine named as "combine" in fact a thresher and harvester.
