Minor channels linked to the main channel irrigate all fields. The need for a second irrigation arises only after about three weeks. The process of irrigating a field is begun by flooding the nearest compartment, followed by the next, and so on. For the second irrigation, these compartments are irrigated in reverse order because irrigation is closed in that last compartment and a minor channel existed there to serve it. This process regulates proper water flow across the whole field.
Farmers ensure optimum irrigation to the desired soil depth by inserting a spade into the soil.
If its blade is completely inserted into the soil, the field is considered properly irrigated. In a few locations, the irrigated soil is thrown upside down. If it splits into pieces, it is taken as a sign of a well-irrigated field. Since water is transported through earthen channels, it results in huge conveyance and application losses due to seepage. The irrigation efficiency is between 50 to 60 per cent.
