The purpose of this study is to test the effectiveness of a starter product at different planting dates.

2017 Kentucky Corn Starter Fertilizer Study - Timing

In theory, the likelihood of seeing a response to a starter fertilizer would decrease if conditions immediately following planting are favorable. Often times, the weather in April is variable but by May, temperatures are warmer and more stable. As evident by the emerged populations and Net Effective Plant Stand (NEPS) counts in 2017, this plot did not have issues with establishment. Consequently, there were no significant yield differences between treatments.
