Question

The supply of water to crops at different intervals is _____________ .
A. Harvesting
B. Winnowing
C. Irrigation
D. Sprinkling

Answer 1

Hint: Plants are used as important food as well as other sources for the human. In humans, the plants are cultivated on a large scale and are known as crops. When plants or animals are cultivated and harvested on a large scale for economic benefit, it is known as crops. Crops are used as food, fodder, oil and fibers. The process through which the crops are grown is known as agriculture.

Complete answer:
The scientific and process of growing plants and livestock is known as agriculture. Agriculture refers to the cultivation of crops that are economically useful and are important food stuffs. The process of cultivation involves several processes which includes soil preparation, sowing of seeds, irrigation, use of manure and fertilizers, harvesting of crop and storage of crops.
The supply of water at different intervals to the crops is known as irrigation. It is the process of application of controlled and regulated water to the crops or plants at particular intervals. The main purpose of irrigation is to help in the growth, maintaining good yields and supply of water to the crops during periods of less than average rainfall. Irrigation of the crops can be done by utilizing sprinklers, pipes, canals. Water is supplied from canals, reservoirs, tanks and wells. Some crops like wheat, vegetables, mustard etc. require less water but other crops such as rice, jute etc. need more water to grow.
Harvesting can be defined as the process of collection of the prepared or ripe crops from the fields. The harvesting of the crops is related to the ripening time period of the crops which may vary in different types of crops. This process may utilize large machinery or done by hand through tools such as sickle or reaper.
Winnowing a technique used in farming for separation of grains from the chaff. It is also commonly used to remove pests such as weevils from the grains. In this process, the mixture of grains is thrown into air which blows away the lighter chaff.
Sprinkling is the type of process of irrigation where water or pesticides are distributed in an uneven haphazard way.

Hence, the correct answer is option (C).

Note: Crops are cultivated and grown for the use on a large scale. The development and yield of the crops depends upon the proper use of water, manures and disease controlling mechanisms. The process of supply of water to the crops at specific intervals is known as irrigation. It is an important step in cultivation of the crops.
