2.Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.
3.Animal husbandry deals with the feeding, breeding, housing and health care of livestock for getting maximum benefits. Livestock refers to farm animals (domesticated animals) such as cow, sheep, etc. kept by humans for a useful commercial purpose.
5.Soil preparation
Before raising a crop, the soil in which it is to be grown is prepared by plowing, leveling, and manuring. Ploughing is the process of loosening and digging of soil using a plough. This helps in proper aeration of the soil. After plowing, the soil is distributed evenly and leveled in the process called leveling. The soil is then manured.
Sowing
Selection of seeds of good quality crop strains is the primary stage of sowing. After the preparation of soil, these seeds are dispersed in the field and this is called sowing. Sowing can be done manually, by hand or by using seed drilling machines. Some crops like paddy are first grown into seedlings in a small area and then transplanted to the main field.
Manuring
Crops need nutrients to grow and produce yield. Thus the supply of nutrients at regular intervals is necessary. Manuring is the step where nutritional supplements are provided and these supplements may be natural (manure) or chemical compounds (fertilizers). Manure is the decomposition product of plant and animal wastes. Fertilizers are chemical compounds consisting of plant nutrients and are produced commercially. Apart from providing nutrients to crop, manure replenishes soil fertility as well. Other methods for soil replenishment are vermicompost, crop rotation, planting of leguminous plants.
Irrigation
Irrigation is the supply of water. Sources of water can be wells, ponds, lakes, canals, dams etc. Over irrigation may lead to water logging and damage the crop. This frequency and interval between successive irrigation need to be controlled.
Weeding
Weeds are unwanted plants which grow among crops. They are removed by using weedicides, by pulling them by hands and some are removed during soil preparation.
Harvesting
Once the crop is matured, it is cut and gathered, this process is called harvesting. Followed by harvesting, grains are separated from the chaff either by threshing or manually in small scale (winnowing).
Storage
Grains yielded are stored in granaries or bins at godowns for later use or marketing. Therefore, methods of crop protection need to be better. In order to protect grains from pest and rodents- cleaning, drying, fumigation, etc are done prior to storing.
Hope it is helpful.

3.) The branch of agriculture that deals with the feeding, caring and breeding of domestic animals is called animal husbandry.
Useful as :
It provides us enough milk from cattles at a large amount.
It provides us eggs and meat at a large amount.
It also cares the breeds that are generally useful to us.
This also provides us enough fish and there meat.
This also gives us honey from bees and wax at a large amount.
5.) Agriculture: The applied branch of biology which deals with cultivation of plants and rearing of animals is called agriculture. Generally, the art or practice of cultivating land is referred as agriculture. The branch of agriculture which deals with food, health and management of animals is known as animal husbandry.
• Agricultural Practices: All activities which farmers do for the cultivation of plants are called agricultural practices.
For doing various activities, a farmer needs different types of tools. These tools which are involved in cultivation of plants are called agricultural implements. Farmers perform agricultural practices in a sequence.
