About DOMIS - Design of micro irrigation systems

Micro-irrigation methods (drip, sprinkler and micro sprinklers) apply water slowly, by depositing water either on the soil surface or directly to the root zone, through a network of valves, pipes, tubing and emitters. Microirrigation methods are most efficient water application methods and need to be increasingly adopted in view of the increasing water demands from non agriculture sectors. There are a large number of considerations, which must be taken into account in the selection of an appropriate micro irrigation system including crop to be grown, water availability and its quality, topography, soil type, weather conditions, availability of labor, energy, technology and financial resources. Design of micro irrigation system specific to the local climate and crops grown in the area need to be developed for efficient inputs uses. A Decision Support System namely "Design of Micro Irrigation Systems (DOMIS)" is presented to help the user to design appropriate micro irrigation systems for efficient water utilization under different agro-climatic conditions for any crop under different sources of water availability. DOMIS includes the design of Drip Irrigation, Sprinkler Irrigation System and Micro-Sprinkler Irrigation Systems. It will evaluate the economic feasibility with detailed cost calculation of the suggested/ designed system. DOMIS provides default data as well as guidance for selection of suitable microirrigation components taking the user through different design steps interactively.

Besides providing the support in designing the appropriate micro irrigation systems DOMIS also provides general information about Government schemes, agencies promoting micro irrigation, implementing agencies in different States of India, approved system suppliers in different States and general information about different districts in the country. It contains detailed district wise climate, information on major crops, crop characteristics, soil type and their properties and ground water data. It also contains information on different types of components and their suitability under different field situations.
