Corn Response Across Plant Densities and Row Configurations for Different Moisture Environments

Table 6

Average plant height, stover yield, yield, test weight, grain N concentrations, and aflatoxin content measured across irrigated and dryland treatments within low- and moderate- moisture environments for five site-years during the 2011 to 2014 growing seasons across northern and central Alabama.
