Precision agriculture requires reliable technology to acquire accurate information on crop conditions. A ground-based integrated sensor and instrumentation system was developed to measure real-time crop conditions. The integration system included multispectral camera and N-sensor for real time Nitrogen application. The system was interfaced with a DGPS receiver to provide spatial coordinates for sensor readings. Before mounting of the sensors on modified paddy transplanter, different mountings and frames were attached with the paddy vehicle to mount the sensors, camera and power source. Battery mounting plate was required to fit imported 12 V & 80 A battery on vehicle. New bracket had fabricated to suit the new battery and it can be adjusted vertically 25~30 mm as per the requirement. For overturning balancing of rice transplanter extra weights of 100 kg were added at the rear of the rice transplanter. Trails were done in puddle rice field. By adding additional weight, there was no problem of over turning in the field in normal operations. The results showed that the integration sensor and instrumentation system supports multi-source information acquisition and management in the farming field except high clearance of tractor.
