Scientists at the Indian Institute of Horticulture (IIHR) in Hesaraghatta have developed a new irrigation method that saves more water than drip irrigation.
According to C. Aswath, chief scientist and head of IIHR's Floriculture and Medicinal Plants Department, this new method was developed on a small experimental field in the institute and uses only one-tenth of drip irrigation water.
Dr. Aswath developed the model that was exhibited at the IIHR National Horticultural Exposition that started on Monday, and he told Hindus that the institute will further test the model on a larger plot.
"The new model is a hybrid (combined) version of two different hydroponic methods, the nutrient film technology (NFT) and the wick system," he explained.
"The main disadvantage of drip irrigation is that it supplies water on the ground. But when water seeps into the ground, it clogs the stomata in the soil. These stomata with oxygen bags are essential for plant respiration. The new hybrid version will not clog the stomata because It works on capillary force," he said. He pointed out that nutrients and fertilizers are supplied to plants through pipelines.
