It is an innovative method of irrigation for sugarcane in which water is applied intermittently to surface irrigated furrows in a series of ‘on’ and ‘off modes of constant of variable time spans. In this method water saving occurs due to decrease in percolation and runoff losses and also faster advance of water through furrows. Studies at Tamil Nadu Agricultural University showed that the saving of water ranges from 35 to 45 per cent in maize and sunflower. |
