Abstract. Precision agriculture is an important source of modern agriculture due to various information that can be collected by data acquisition tools. Wide range of tools have been developed and commercialized to collect information on soil, crop, and other related parameters. Crop yield and quality is most important information for PA, and yield monitoring system is a tool to collect crop yield in real-time while combine harvests crops. Generally, yield monitoring system consists of a grain flow sensor, a grain water content sensor, a cutting width sensor, a harvester speed sensor, and a location sensor (e.g., GPS). The collected sensor data are transmitted to a cabin-mounted user console for data processing, screen display, and storage. Modern yield monitoring consoles are usually tablet computers functioning central data, screen display, and data input and storage features. Although many types of user consoles are commercialized in many countries, no commercial products have not been available for small sized combines mostly used in Korea. This study was conducted to develop a user console software for grain yield monitoring system that can be used for Korean combines. First, commercial products were surveyed and analyzed to design menu structure that should be included. Then, some other features necessary and unique for Korean users. Console display could be divided into two parts: texture and graphic parts. The menu could be classified as a map, graph, and data. The type of the yield map was chosen as dot map type (used the raw data), because real-time mapping must be displayed at least 1 second for comfort. The yield was calculated cutting width, harvester speed, grain flow, grain water content while harvesting the crop. These data were used to make statistic graphs. Contents of the graph were yield (average, sum, etc.) harvested area, so users can easily check the data. The information was also displayed on the display. Especially, working direction is important due to efficiency and result of the yield map. So working direction used location, heading was inputted on the display including yield, grain flow rate, grain moisture contents, harvester speed, and location. These functions and contents were based on the commercial products. But there were not products available for small sized combines mostly used in Korea. As a result, we considered and inputted some information such as working direction to prevent duplicating the data and yield map.
