Abstract
It is important to collect, arrange and conjugate the abundant information on a rice field for the development of business in the paddy farm. Therefore, farm managers need a computer system on field management of paddy farm. But these ready-made or developed computer systems partly treat the information on a rice field and often pose some difficulties about the operability and the price, so they have not been widely accepted. Thus in this research, we developed a computer system on field management of paddy farm using of a mapping system with fundamental drawing function. The contents of its system and the outline of its application is as follows. First, users will make a wide blank map area linked each blank maps which have been made by digitizer in accordance with a farm map. Next, input four kinds of data (land resister, planting resister, growing management resister, resister of partial farm work contract) will be inputted in accordance with a wide area blank map. Then, these data can be used to support a farm manager's decision-making on the following points. 1) It can stimulate effective land use because farm managers can accurately grasp the right of land, rice field attributes and actual land use condition. 2) It can simulate putting together pieces of land recovered from rice to another crop and their rotation method. 3) It can facilitate planning the data of planting and operation because farm managers can accurately check a planting field and area under operation. 4) It can sharply reduce office work because farm managers can automatically calculate the cost of partial farm work contract and a farm rent.
