Irrigation

Jharkhand's agriculture is rainfed and the monsoon is ridden with

uncertainty. Therefore irrigation becomes

more important here

Approx 11% of the total cultivable land of Jharkhand is irrigated.

58.3% of the total

irrigated land is irrigated by surface water and

41.7% by ground water.

ans of Irrigation

WELLS:

This is the oldest and most commonly used means of irrigation in Jharkhand.

29.5% of the total

irrigated land of Jharkhand is irrigated with the help of wells.

Gumla district comes first from the point

of view of well-based irrigation (87.2% of the total irrigated land). Giridih (77.9%), Ranchi (71.4%),

Dhanbad (56.2%), Hazaribagh (52.7%) and Singhbhum

(17.5%) next come.

TUBEWELLS

Tubewell is the well of the modem times. Water is extracted from deeper levels of earth through a pipe

with the help of electricity or diesel driven pump sets.

Limited development of tube wells has taken

place in Jharkhand particularly due to hardness of the

rocks in the plateau region.

8.4% of the total

irrigated area of Jharkhand is irrigated through tubewells.

Tubewells are used the most in Lohardaga

(32.6% of the total irrigated area)

and least in Deoghar district (3.8%)

PONDS

Ponds are another important means of surface irrigation.

Ponds have been the main means of

irrigation since the ancient times in Jharkhand.Most of the

irrigation is carried out by means of ponds

in the Deoghar district (49.3% of the total irrigated land).

Next comes Dhanbad (43.8%), Sahebganj

(27.7%), Dumka (27.7%) and Godda (26.6%).

CANALS

Physical environment of Jharkhand is not suitable for canal

irrigation. Yet small dams have been

constructed on the

rivers of Jharkhand and canals have been taken out from

the reservoirs which are

used for irrigation.

17.13% of the

total irrigated land of Jharkhand is irrigated with the help of

canals.

Canal irrigation is mainly used in Singhbhum region.
