Raising corn is a complex and challenging endeavor no matter the year or the environment, but one of the most challenging parts of raising corn is ensuring the corn crop is producing yield all the way to black layer. Why is this so important? Because at dent stage, also known as R5, 65% of the dry weight of the kernel still needs to be accumulated. That 65% could easily equate to 20% to 25% of the final yield or 40 to 60 bushels of grain.
The adage that once the corn reaches dent the yield is made and nothing can hurt it is a false statement. In corn production, agronomists talk about the length of grain fill and the longer a corn plant can accumulate dry matter, the higher the yield (not potential, actual yield). The extra time correlates directly to the importance of the R5 stage.… Continue readingRead More »
