Corn morphology, mass, and grain yield as affected by early-season red: far-red light environments
The spatial arrangement among plants affects both vegetative and reproductive meristem development. More axillary meristems develop at lower plant densities, which are associated with relatively high red:far-red light ratios (R:FRs; 645:735 nm). However, little is known about the effect of R:FR on corn (Zea mays L.) productivity. We conducted field research to determine the effect of early-season ...

Stacked corn hybrids show inconsistent yield and economic responses in New York
Stacked (two to three transgenic traits) corn (Zea mays L.) hybrids represented 40% of U.S. corn in 2008, despite limited agronomic studies. Field-scale studies were conducted on four farms in New York for 2 yr to evaluate the agronomics and economics of double-stacked {glyphosate resistance and Bt (Bacillus thuringiensis) European corn borer [Ostrinia nubilalis (Hübner)] trait} hybrids when ...

Managing Moisture: Navigating Drydown Decisions
This season has been, without a doubt, one of the wettest since 2009. In many states, the excessive rain led to flooding and late planting. On my family farm in North Central Iowa, like on many farms throughout the Corn Belt, it was so wet that we couldn’t get into the field to plant on schedule. And the continued wet weather means that now high and variable grain moisture levels are ...
