Overview

Water scarcity and inefficient water resource management technologies are the main challenges in developing countries like India. India has only 4% of the World's freshwater resources, out of which 85 % of water is used for agriculture. Irrigation is the backbone of agriculture, and the efficient utilisation of irrigation water is possible only by the adoption of highly efficient irrigation methods, such as micro irrigation. Micro-irrigation provides water to plant(s) in precise amount, at right time and at appropriate place. In this course contains the basic fundamentals of fluid mechanics, flow through pump, filters, pipes and water dispensing from fine small orifices. The course also covers design, installation, operation, automation and evaluation of micro-irrigation system. This course will be useful to the Graduate, Post Graduate and Ph. D students of Agricultural Engineering, Civil Engineering, and Agricultural Science. This course will also be useful to Micro-Irrigation Industry professionals and field practising Engineers.INTENDED AUDIENCE : Students and Faculty of Agricultural Universities,IIT, NIT, Micro irrigation Industry professionals,Researchers working in the area of Precision Agriculture and EntrepreneursPRE- REQUISITES : B.
