Modern Hybrid Corn Makes Better Use Of Nitrogen
2012-04-30 10:46:38

Today's hybrid corn varieties more efficiently use nitrogen to create more grain, according to 72 years of public-sector research data reviewed by Purdue University researchers. Tony Vyn, a professor of agronomy, and doctoral student Ignacio Ciampitti looked at nitrogen use studies for corn from two periods — 1940-1990 and 1991-2011. They wanted to see whether increased yields were due to better nitrogen efficiency or whether new plants were simply given additional nitrogen to...

It might not look like there's much going on in those roadside corn fields, but a Purdue University researcher has shown that corn plants are in a fierce battle with each other for resources. Tony Vyn, a professor of agronomy, said it's been known for a long time that young corn plants are, on average, shorter in no-till, corn-on-corn fields, but that doesn't mean there is an overall stunting of growth among all plants. Instead, residue left over from last year's corn crop is changing soil...
