University research and extension are critical in equipping producers and agronomists with the information they need to continue advancing corn production in Iowa. Incorporating new scientific findings and recommendations into today's agricultural systems must be our priority to consistently produce a high quality crop that is also economically feasible.
Corn in grain development stages from here on out
Lori Abendroth and Roger Elmore
22 July 2010
Nearly all corn fields across the state are now tasseled and in the early reproductive stages. Stress encountered early in the grain fill period (blister (R2) or milk (R3)) will result in kernel abortion. Stress experienced later during the dough (R4) or dent (R5) stages will result in lighter kernels. Read for more information on grain fill and what to be aware of.
