In the competitive global trade generation, to promptly obtain the information of agriculture is the most indispensable advantage. Instantly integrating resources for agriculture could effectively enhance the competition of agricultural industry and improve its business model.

Through analyzing the prices of crops and the agricultural information of electronic farms which are offered by Council of Agriculture with the assistant system of production decisions, the results will be represented in bar charts and line charts which provide the information for farmers to evaluate the production. The research would like to enable farmers to accurately manage the fluctuation of price and quantity; then, decide how to adjust the production; in the end, effectively reduce errors during making production decisions.
