The region of Campos Gerais in the State of Paraná, Brazil, is a pioneer in the implementation of new technologies, with superior grain yield performance. No-tillage farming system, for instance, is widely adopted in this region. This particular system requires accuracy and precision in the planting process to achieve high grain yields. Regarding regional attributes, the corn planting process in Campos Gerais under no-tillage was evaluated. Forty-eight properties were selected for a plant population pressure analysis. Four or five planting rows delimited the study area, 3m per row. The spacing between plants and between rows was measured. No significant differences were observed between planting rows in 42 properties, and the average coefficient of variation was around 33%. None of the areas had an average lower than 50.000 plants ha-1, the lowest value recommended for the hybrids in study. The regional planting process can be considered efficient regarding the number of plants per area. Nevertheless, the high variability found on plant distribution in the planting rows suggests the need for further research and extension measures.
