Pioneer tests corn hybrid response to plant population at several locations across the U.S. each year. This extensive testing allows us to sample a wide array of environments at many yield levels to help you find the best planting rate, by product.
Information and results contained here are estimates based upon plant population data collected by Pioneer Agronomy Sciences to determine economic seeding rate and plant populations. Such tests are done on a genetic family basis. For data quality purposes at least 6 locations are required and if a hybrid is not listed, we currently have insufficient data. All products within a family receive the same recommendation unless observations indicate a significant difference. Individual product responses are variable and subject to any growing environments including soil type, weather, insects and diseases. This model may not predict future performance and may not be complete.
