The Precision Farming Development Centre (PFDC) at Water Technology Centre, ICAR-Indian Agricultural Research Institute (IARI), New Delhi, India, has took initiative to develop a web based decision support system for designing micro irrigation systems. A Decision Support System namely, DOMIS (Design of Micro Irrigation Systems) has been developed to help the user to design appropriate micro irrigation systems for efficient water utilization under different agro-climatic conditions in India. DSS-DOMIS is capable of designing drip Irrigation, Sprinkler Irrigation and Micro Sprinkler irrigation systems layout. As a part of the decision support mechanism, the DSS provides expert opinion and necessary data on crops, soil, water and climate as default options with a provision of change if the user so desires.

Salient Feature :- The web based system ( ), uses scientifically accepted software algorithms with richness of information and expert opinions, flexibility and simplicity of use which makes the DSS DOMIS a superior tool for designing micro irrigation systems with a view to enhance water productivity in agriculture. Besides providing the support in designing the appropriate micro irrigation systems DOMIS also provides general information about Schemes of Government of India, 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. The developed DSS has been tested and appreciated by 22 Precision Farming Development Centres, State Micro Irrigation Mission Directors and several micro irrigation industries. The decision support system will be useful for farmers, researchers and policy makers.
