If the person is a pisciculturist does the breeding, hatching and rearing of fishes.

Food Corporation of India (FCI) is the Government Agency which procure food grains from the farmers.

The animals producing milk are called milch animals, e.g. cow.

No, the time and frequency of irrigation is not same for rice and cotton. It varies from crop to crop.

Some tools useful in ploughing and levelling are wooden plough, iron plough, soil plank, etc.

Yes, cultivator has an advantage as its use saves time as well as labour by digging into a considerable area at the same time.

Traditional methods of irrigation are dhekli and moat and modern methods are sprinkler system and drip system.

Pumps are commonly used for lifting water

The same kind of plants grown and cultivated on a large scale at one place is called a crop

Pea and mustard are two examples of rabi crops.

The planting of a leguminous crop in a field has the same effect as adding nitrogenous fertiliser in the field. They can fix atmospheric nitrogen themselves by using nitrogen-fixing bacteria in their root nodules. Therefore, nitrogenous fertilisers are not required for growing leguminous plants.

Preparation of soil - It is the first step before sowing the crop. In this, the soil is ploughed to loosen it and make it aerated which allows the roots to breathe easily. This also helps earthworms and microbes in the soil that bring the nutrient rich soil to the top. The process of loosening and turning of soil is called tilling or ploughing, which is followed by levelling and manuring.

Various agricultural practices are as follows:
(i) Preparation of soil The first step is preparation of soil. The soil is loosened and turned up. It helps the plants to grow and develop. The process of lossening and turning of the soil is called tilling or ploughing. Sometimes manure is added to soil before tilling.
(ii) Sowing After preparation of soil, the second step called sowing takes place. Before sowing good quality seeds are selected. The seeds should be clean and healthy.
(iii) Adding manure and fertilisers Soil supplies minerals and nutrients to the crops. These nutrients are essential for growth of plants. Sometimes these nutrients are lacking, so substances are added to maintain or to replenish the soil. These substances are called manures and fertilisers. Manures and fertilisers are essential to increase the crop production
(iv) Irrigation The process of watering the crop plants is called irrigation. Plants take all the nutrients and minerals in dissolved form. So, water is most essential for germination of seeds, growth and development of plants.
(v) Harvesting After maturation of crop, it is cut off. This process is called harvesting. It is done by a sickle or by a machine called harvester.
(vi) Storage Storage of product is one of the most important tasks. To keep the grains for longer time, it should be safe from moisture, pest, insects and other microorganisms.

(a) Paddy is cultivated in rainy season as it is a kharif crop.
(b) For sowing paddy, seeds are first grown in a nursery and later seedling are transplanted in the field. This allows us to select only healthy and better seedlings for cultivation.
(c) Measures taken to prevent spoilage or damage of harvested crops from insect attack are:
(i) Exposing them in sunlight for drying as freshly harvested crops have moisture.
(ii) Dried neem leaves are added to stored grains, so as to prevent damage from pests.
(iii) Specific chemical treatments are also available for preventing crops.
