Question

Which of the following was a major source of water for irrigation?
a. Dams
b. Canal
c. Rain
d. Both A and B

Answer 1

Hint: Irrigation is a technique of watering crops. The ancient or traditional methods of irrigation were very direct but as time evolved, the new and modern methods of irrigation have taken over.
The methods used nowadays are sprinklers, surface irrigation, drip, and subsurface. All these methods are very important to the farmers.

Complete answer:
Irrigation is the technique of supplying water to agricultural land. Water is provided at regular intervals in set amounts to the crops. It helps in keeping the soil moist and appropriate for the crops.
There are modern and traditional methods of irrigation.
Traditional methods have been practiced by the farmers for decades and are way cheaper.
They are inefficient to some extent and it does not guarantee even distribution of water to all areas.
It involves a higher rate of water loss. Most farmers do it themselves with the help of cattle by drawing water from the well and canal.
Rain is also a type of irrigation but it cannot be considered within the methods of irrigation because it is seasonal.

Hence, the correct answer is option (D).

Additional information:
> Rain can only provide water to the crops for a stipulated time and the rest of the year there is drought serene cannot be considered as the major method of irrigation.
Therefore, option (c) is the incorrect answer.

> Dams and canals are the major traditional sources of irrigation since ancient times because the development of dams near agricultural fields helps farmers to get a source of water nearby.

> Thereby this helps in watering the crops similarly can also be made to help the farmers in irrigation.
Therefore option (a) and option (b) both are correct.

Note: Irrigation is very important in agricultural productivity.
A lot of factors affect the agricultural product and produce but the most important of which is water availability. There are regions in India where there is very little rainfall and scarcity of rainfall can lead to a lack of moisture in the soil. The most important feature of the growth of crops is the soil being.
Too much water supply or too little water supply affects the crops badly hence the irrigation system helps in a good batch of crops but maintains water supply.
