A new system to record growth data for fruit vegetables has been developed. Nodes of crop plants are tagged with a QR code, allowing researchers to record growth events using a tablet PC. Growth data are stored in a database, and tagged with the date and time. As an implementation case, differences in growth of cucumber caused by carbon dioxide gas and mist application were recorded by using the new system. The system allowed acquisition of in-depth data (such as the location where a fruit was harvested, the number of days from bloom to harvesting, and the number of flowers that did not produce fruit) which were previously difficult to acquire, as well as the yield per plant, facilitating analysis. The new system also made it possible to illustrate the growth of individual crop plants, from planting to harvest, as an animation.
