The limited natural resources, high cost of agro-inputs and environmental degradation are promoting precision agriculture, the drones have become widely available for use in agriculture aerial imagery of fields, these can be analyzing drone map data to understand the health of crops. The objective of this paper was the fast analysis of plant health, nitrogen status, and plant count in maize crops using drones. In our field, plant health is better in low areas. The total area with nitrogen deficiency is 14% of the field, spot in high areas, so that management actions on identified areas are recommended. Plant count analysis reports 20, 964 plants. The fast information obtained for drones and software can take action quickly to remedy some agricultural common issues.
