Microirrigation allows an efficient watering by supplying required quantity of water at small rates and near the plant roots. Agricultural sector needs software to design efficient micro irrigation systems taking into account the local soil, crop, water and climatic conditions. A Decision Support System- for designing Micro Irrigation Systems namely ‘DOMIs' was developed to fill the requirementand to support the digital India initiative and the goal of per drop more crop. 

DSS-DOMIS is capable of designing drip Irrigation, Sprinkler Irrigation and Micro Sprinkler irrigation systems .The DSS provides all necessary data on crops, soil, water and climate as default options with a provision of change if the user so desires. DSS-DOMIS suggests most optimal lay out plans for main, sub-main andlateral pipes. It determines the appropriate sizes of different components including main, submain and lateral pipes, pumping system, filtersand fertilizer application systems.DSS also provides an estimate of the costs of the designed system. The developed DSS has been user-friendly interface developed in open source programming languages i.e PHP, MySQL and runs in Apache server uses rich database with information on crops, soil climatic data, microirrigation equipments as well as, source and quality of water.  

The web based system is developed using scientifically accepted software algorithms with richness of information and expert opinions, flexibility and simplicity of use, which makes the DSS DOMIS superior to others in the field. The developed DSS was tested and appreciated by 22 Precision Farming Development Centres and leading irrigation Industries.
