According to Nielsen, focusing on these yield components will help you narrow your search to specific periods of the growing season simply because the various yield components are "determined" or "set" at different times of the growing season. If yield in a particular field appears to be limited by insufficient plant population, for example, YIFs that impact seedling emergence and survival such as soil compaction, planting date and starter fertilizer would be likely candidates for improvement.
The most prevalent YIFs worldwide, Nielsen says, are those related to water management. Many corn producers are considering ways to conserve soil moisture or provide supplemental water in 2013 following last year's drought. While these YIFs are certainly important in times of limited precipitation, Nielsen will also remind growers that particular YIFs may not be important every year in a given field. As we move through the 2013 growing season, insufficient soil drainage may instead prove to be a key YIF in Michigan fields.
To learn more about YIFs and other production points for 2013, register for MSU Extension's Online Crop and Forage Highlights. Details on viewing site locations are also available on the event website. Once registered, online participants will receive an email containing a link to connect to the programs. Each event will offer MAEAP Phase I and two MDARD Pesticide Recertification Credits for application to the Private Core, Commercial Core or Field Crops categories.
