Exudation – An Advancement in Micro-Irrigation with Sub-Surface Drip Irrigation (Porous Pipe)

Abstract

The awareness has slowly been developed for careful and effective utilization of natural resources like water and energy. Exudation, i.e., sub-surface irrigation with porous pipe can be an efficient water-saving method of irrigation for many less developed arid and semi-arid regions. Sub-surface drip irrigation, i.e., SDI has been an important part of agricultural irrigation throughout the world. During last three decades, sub-surface irrigation system is being used owing to its capability to apply water efficiency, low labor and low energy requirement and increase in quality and quantity of crop yield. The project work deals with introduction of new method of irrigation, the comparative study of conventional methods with exudation, i.e., SDI also studied. The project work also discusses use of sub-surface drip irrigation (SDI) for grapes and pomegranates. It also deals with benefits over drip irrigation, lacunas in conventional drip irrigation system. The main objective of this project work was to minimize evaporation losses in grapes and pomegranates, proper utilization of water, energy saving and minimization of labor cost and maintenance.
