(ii) Furrow Irrigation Method
(iii) Strip Irrigation Method
(iv) Basin Irrigation Method.
2. Modern Irrigation Methods:
(v) Sprinkler Irrigation Method
(vi) Drip Irrigation Method
(vii) Pot Irrigation Method.
1. Traditional Irrigation Methods:
(i) Check Basin Method:
In this method, the whole field is divided into basins according to the capacity of water. Basins are connected through a ‘Dhora’ (A small drain type flow way), which has raised earthen walls on both sides. ‘Dhora’ is of two types, one is the main ‘Dhora’ and the other ‘Dhora’ is connected to basins. Size of basins are made according to the inflow of water.
These basins are surrounded by small furrows. Branch ‘Dhora’ flows towards the slope from the main ‘Dhora’. If the slope of branch ‘Dhora’ is steep, ‘mooonja’ or polythene is spread in it to prevent erosion of sides. The main source of water is located at the highest place in the field.
The width of drains is affected by factors like flow of water, percentage, slope and structure of the ground etc. The length of ‘Dhora’is different depending on the basis of slope and formation of the fields. This method is also prevalent in India as it does not cause any burden on the farmer.
