The paper treats the analysis of possibilities how to make web applications of the agrarian web portal Agris accessible to mobile devices of various platforms. The principal requirements for the mobile version of the application are: a possibility to be functional off-line, the implementation of all basic modules (papers, prices, warnings) and a conservative design. On the basis of the agrarian web portal Agris analysis we postulated a concept when a native mobile application for the Android platform, a hybrid mobile application for the Android, iOS and Windows Phone 8 platforms and an optimal valid web output for mobile web browsers (responsive layout) will be developed. Native and hybrid applications will allow users to work both in online and off-line modes. The access via a web browser will require a permanent connection. The proposed solution of mobile versions of the agrarian web portal Agris represents a universal solution of problems with mobile access to information sources when rural areas are not adequately covered with a high-speed wireless connection to the Internet, in contrast to a large extension of modern mobile devices.
