Plant Irrigation using Porous FRP Tubes Feasibility Study

Agriculture still continues to be the most important means of livelihood for a large number of rural Indians. Therefore tackling the problems posed by drought becomes one of the most crucial tasks for the Government. It is also commonly believed that it is possible to conserve irrigation water through managing the discharge efficiently. Drip irrigation provides an efficient alternative but is rather expensive. With this as the back drop, juxtaposing with scenarios of recent development of new materials at premier institutes like NAL, the Council undertook a project with the primary objective of exploring the possibility of plant irrigation using FRP tubes. Drip irrigation is a very well known method of ensuring the right amount of water in the locality of the plant growth. But the nozzles used at the delivery end suffer from the defects arising out of flow blockages due to impure water (suspended particles) or due to natural corrosion of the metal. Leakages at the junction between the nozzles and the delivery tube have also been observed. Scientists working in the area of materials - plastics - feel that porousFRP tubes can be developed with the right degree of porosity to ensure the correct amount of discharge of water in the locality of the plant growth.
