Irrigation is important in the field of agriculture to grow crops.

BECAUSE IT IS IMPORTANT.

Irrigation is neccessary because for giving water to plants in sense that for making them grow healthy and nice growth for them. As you know water is very essential for water so irrigation is neccssary.

The plants need water to grow 

it is necessary for the growth of plants and proper irrigation is required if not the plants might not be able to grow properly

without irrigation plants die
 they cant survive
 

irrigation is necessary because none of the plants can live without water . water has minerals in it.

Hi,
Irrigation helps in providing moisture to the crop for germination.
It helps in making the soil wet which makes the ploughing of land much easier.
It also helps in protecting the plants from frost and hot air currents.
hope this helps.
 

dont you have common sense u r asking that why plants need water?? hahahhahaa

ddd

It facilitates the growth of plants and also helps in the germination of seeds. It provides the plants the necessary minerals too.

It is important because crops will die without water

B'coz plantrequireswater fr its growth for moisture

Irrigation is necessary because it saves the plant from frost and hot air.

The artificial way of supplying water to the agricultural land at the right moment in an appropriate volume for the proper growth of the plants in order to get the maximum yields of cultivation is technically called irrigation. But irrigation also includes clearing away of excess water from the agricultural land.

There is a great necessity of irrigation in Indian agriculture. India has a great diversity and variety of climate and weather conditions. These conditions range from extreme of heat to extreme of cold and from extreme dryness to excessive rainfall. Due to some reasons irrigation is needed in Indian agriculture.

1. Uncertainty of Monsoon rainfall both in time and place.
2. Irregularity in distribution of rainfall throughout the year.
3. Excessive rainfall causing flood.
4. Draught is an annual event in some areas.
5. India is a land of Rabi Crops. But there is not rainfall in winter months.
6. Some soils need more water.
7. Introduction of H.Y.V seeds and multiple cropping need water throughout the year.

The types of Irrigation mainly practiced in India are:

1. Tanks
   (a) Sichhni, (b) Donga
2. Well
   (a) Dug Well, (b) Tube Well: (i) Shallow. (ii) Deep.
3. Canal
   (a) Perennial, (b)   Non-Perennial

Irregularity in  distribution of rainfall through the year..

A good crop yield require water.Seeds do not germinate in the absence of water.Hence irrigation is necessary.

watering plants is necesssary

irrigation is important because all the plants will get all the sunlight nutrition and water properly

so that plants get water to carry out photosynthesis

so the plants can grow well

The annual average rainfall in India is about 120 cm, i.e. slightly more than the global mean of 99 cm but still due to improper management and pollution , we are not able to use that water and it goes wasted by draining into saline oceans . Irrigation in india is very important because 
1. Indian monsoons are highly erratic . Depending on rain might not yield better crop results . 
2. Rice which is grown both as a commercial and staple crop requires a lot of water . 
3. HYV seeds which have been introduced , require a lot of irrigation . 
4. Indian economy is an agrarian economy , thus irrigation is necessary to produce good quality yields.

Irrigation is necessary to improve the fertility of the soil and it can be used for the whole year. Because some farmers depend upon the rains that is why irrigation method is used.

because it helps in germination of seeds

irrigation is necessary because it prevents the plant from frost and dry climate. it helps loosening of soil. plant can take nutrients from the soil through taking water from the soil
