The farm owner relied heavily on workers to operate and maintain his rock melon farm, from ploughing and seeding to watering and fertilizing of the crops. Thus, human errors are inevitable. He had to deal with inconsistency in irrigation and fertigation process. Issues were more apparent during days when he was away from the farm. As a result, his material cost was always high, crop’s health badly affected, and he was not able to predict his crops yield almost in every season. He knew the only way for him to mitigate all these issues is to replace part of the manual works with technology.
