Environmental conditions is important factor affects the agricultural production system. In four seasons country like Japan, weather condition during cultivation can be fully controlled by utilization of greenhouse and environmental management. Microclimate manipulator can be managed automatically based on environmental evaluation. However, in tropical country like Indonesia, utilization of automatic control on greenhouse for agricultural production system is still rare because of the operational costs and the economic aspects. Thus, here we try to utilize the Information and Communication Technology (ICT) to improve the agricultural production system on tropical agriculture by implementation of regular environmental measurement using Field Monitoring System (FMS), Real-time environmental evaluation and information processing, and provision of decision support on farming activities. We realize that the incorporation of farmer’s knowledge and utilization of ICT would be able to support modern agriculture and also promising the progress on towards precision agriculture.
