Page Title ISU CORN TEST yields objective point of view Computer technology is an important part of the ISU Corn Yield Test.
Researchers gather reams of information on each of several hundred hybrids on multiple test plots.
A small test combine rolls through the field while Mahaska County farmer Larry Linsley holds up a kernel of corn and inspects it. Like a textbook with endless footnotes, the numbers being tabulated in the combine and the corn going through it will tell Linsley what he needs to know for the next level of profitability on his farm. This is a test, after all. Indeed, it is not just any test. It seems like every seed company always wins its own contest.
