Nucleus O-Phos™ 8-24-0-.10 Fe for in-Furrow Applications As Starter Fertilizer in Corn.

In-furrow starter fertilizers for corn (Zea mays L.) has been a common practice throughout most growing regions in North America.  Research has shown an increase in early growth and development, as well as increased grain yield when utilizing starters.  Helena Chemical Company’s Nucleus O-PHOS™ 8-24-0-0.10 Fe was applied at a rate of 28.06 L ha⁻¹ in eleven locations over three years: 2013 (6), 2014 (2), and 2015 (3).  Field trials were placed in MN, WI (2), VA, PA, MD, ND, NE, IL, NC, and TX.  All testing locations performed best management practices to promote optimal yield.  Grain yield was analyzed within years and between only Nucleus O-PHOS™ and the Grower Standard Fertility Program (GSP).  Corn grain yield was higher when treated with Nucleus O-PHOS™ than the GSP from 2013 to 2015.  These data suggest that Nucleus O-PHOS™ is a beneficial starter fertilizer option for enhancing corn grain yield.
