Abstract
The aim of this study is quantifying and modeling know-how about the cultivation of the mandarin orange so that even an amateur may perform the sophisticated work for cultivating the mandarin orange. Generally speaking, it is said that choosing the best time of watering is important for growing high-quality mandarin orange. Although it is very difficult to decide a timing of the watering, an expert farmer usually decide it by watching whether a fruit tree is energetic or not. It is said that such decision is very intuitive or that the decision would depend on watching whether the leaves are withering up or not. In this work, we develop a sensing system for cultivation of high-quality mandarin oranges that can measure the condition and the growing power of the tree. In this report, we present the overview of the system and its preliminary observation result.
