We’ve been hearing a great deal about how getting high corn yields is mostly a matter of following a “formula” that combines “best” hybrids, high fertilizer rates, high plant populations, narrow or twin rows, and foliar fungicides, with failure to use any of these higher inputs likely to result in low yields. At the same time, the weather in 2010 and problems that carried over from the 2009 season meant lower than expected yields in many fields, even where high inputs had been used. We’ll look at current research results to see if in fact “more” is always “better” when it comes to corn inputs.
