The new one, a hybrid version of two hydroponics models, requires only a tenth of water used in drip irrigationScientists at the Hesaraghatta-based Indian Institute of Horticultural Research (IIHR) have developed a new irrigation method, which conserves even more water than drip irrigation. In this model, water is circulated through a pipe that is laid underground. “The main disadvantage of drip irrigation is that it supplies water above the ground. The new hybrid version does not clog the air pores as it works on capillary force,” he says. He wants to take up another experiment to know whether the hybrid model helps in purifying chloride water from deep borewells.
