The online data management system for on-farm trials (WebFarm) is a prototype software to customize recording of on-farm trials under the Indian Agricultural Statistics Research Institute, New Delhi. The prototype WebFarm is a three-layered design. Client Side is the Interface Layer, implemented in HTML and JavaScript. Server Side is the Application Layer connecting the client side layer and the database and is implemented in Java Server Pages.Database layer is implemented using Microsoft Access 2000. The developed WebFarm can be implemented as a network-based system with a server, so that information is available online. WebFarm runs on any node of the Internet through a browser. Security features are provided in such a way that only the administrator can access the database. It has facilities for browsing and searching the information and online help for smooth navigation. There is a provision for interacting with the System Administrator through e-mail. This will reduce the delay in receiving the data. Further, IASRI can distribute the work, like—checking of schedules, coding of data and converting data to electronic form to various centers conducting on-farm trials. As a result, they can be directly used for statistical analysis.
