Answer 1

Agriculture is a branch of biology that deals with the cultivation of plants and the rearing of animals. Agriculture refers to the art or practice of cultivating land in general. Animal husbandry is the branch of agriculture that deals with the food, health, and management of animals.

Complete answer:
Preparation of soil: The first step in growing a crop is to prepare the soil. It is beneficial to turn and loosen the soil for the roots to penetrate deeply into it. The loosening of the soil encourages the growth of a variety of soil microbes, earthworms, and other beneficial organisms that enrich the soil with humus and other nutrients. Plowing is the process of turning and loosening. This is done with the help of a plow, a hoe, and cultivators.
Sowing: Sowing is the process of planting seeds in the ground to grow crops. For sowing, we must use high-quality seeds. Sowing is done by hand with the help of mechanical equipment such as Seed Drill. Few plants, such as rice, are grown in a separate area before being transplanted into the fields.
Weeding: Other undesirable plants may grow alongside the crop in a field. Weeds are the name for these unwelcome plants. Weeds are removed in a variety of ways by farmers. Tilling before sowing crops, physical removal of weeds by uprooting or cutting them close to the ground, and the use of weedicides are all examples of weed control methods.
Threshing: The process of separating grains or seeds from the chaff is known as threshing. It is carried out after the crop has been harvested. It's usually done with the aid of a machine called a 'Combine.' This machine is a harvester and thresher in one. It both harvests plants and cleans grains.

Note: The threshed grains are dried out in the open. The dried grains are stored in gunny bags and placed in godowns, which are cemented halls with proper ventilation. Dried grains are stored in jute bags, metal bins, or mud bins by farmers. Grain is stored in silos and granaries on a large scale. Chemical treatments are used to protect large quantities of grains stored in large godowns.
