2. Determine Row Spacing: Next, determine the desired distance between rows. Traditional row spacing for corn is commonly between 30 to 40 inches, but precision planting techniques may allow for narrower row spacing.
3. Calculate Plant Population: To calculate the plant population per acre, divide the number of inches between rows by the average spacing between plants within a row. For example, if you have 36-inch row spacing and the desired spacing between plants is 10 inches, the calculation would be: 36 inches (row spacing) / 10 inches (spacing between plants) = 3.6 plants per row foot.
4. Convert to Plants per Acre: Multiply the plant population per row foot by the number of row feet per acre to determine the number of plants per acre. For example, if you have 3.6 plants per row foot and your acre consists of 43,560 square feet, the calculation would be: 3.6 plants per row foot x 43,560 square feet = 157,296 plants per acre.
5. Account for Germination Rate: It’s important to consider the germination rate of your corn seeds when calculating the number of seeds required per acre. If your seed packet specifies a germination rate of 90%, multiply the number of plants per acre by the reciprocal of the germination rate. In this case, the calculation would be: 157,296 plants per acre / 0.9 (reciprocal of 90%) = 174,773 seeds per acre.
6. Adjust for Seed Quality: Lastly, consider the quality of your corn seeds. Some seeds may have lower germination rates or may be damaged or non-viable. It’s recommended to account for this by adding a seed quality factor. For example, if you estimate that the seed quality factor is 95%, multiply the number of seeds per acre by the reciprocal of the seed quality factor. In this case, the calculation would be: 174,773 seeds per acre / 0.95 (reciprocal of 95%) = 184,037 seeds per acre (rounded up to the nearest whole number).

By following these steps, you can accurately calculate the number of seeds required per acre for your corn crop. Remember to consider factors such as seed spacing, row spacing, germination rate, and seed quality to ensure proper plant population and maximize the potential for a successful and productive harvest.
