Some of the late April planted corn is beginning to tassel this week, July 8-12. Generally, 60 days after tasseling, corn will have reached physiological maturity. Physiological maturity doesn’t mean that the corn is harvest ready; it means that the maximum dry matter level has been reached in the kernel—black layered—and grain moisture is approximately 32%….

When will this year’s corn tassel? Many have heard the old saying “knee high by the 4th of July.” Last year, my 111 day corn was tasseling on July 1, but this year’s corn was planted 5 days later, April 29 & 30, and our daily temperatures have been cooler—fewer growing degree days—resulting in a later…

On May 18, I observed my first flowers on our soybeans—planted May 1, 2013. Soybeans are photo period sensitive plants, meaning that they transition from their vegetative phase to reproductive phase in response to this shortening of day length. Summer solstice, June 21, is normally the longest day in hours of daylight for the year. After…

As summer arrives on June 21, 2013, I am observing a phenomenon occurring in some of our corn fields. Observations The event I am seeing is that the last emerged corn leaf is light green or almost white colored. The cause for these light colored leaves is good growing conditions for the plant. The light colored…

The condition of the year’s corn crop varies from looking good to drowned out. Many of the growth problems are associated with the amount of rainfall received and the drainage for each field; the better the drainage, the better the crop appearance. Observations During May 2013, the Ag 10 Research Center received 8.75 inches of…

For some farmers this year, 2013, “Prevented Planting” is a reality. What are my options after discussing the situation with my insurance agent? Prevented Planting Options Plant soybeans on those corn prevented planted acres. This will dramatically reduce the corn root worm presence. This will reduce N requirement by 40-to-50 lbs. N compared to continuous corn recommendation….

Now is the time to consider a post N application. Our corn is planted and a significant rain event occurred over the Memorial weekend. This rain event has possibly moved the applied N deeper into our soil. With this deeper movement of the applied N into the soil, the amount of root available N currently…

I am concerned with the amount of non-treated soybean seed available for this year’s planting. For the four varieties I received for 2013 planting only one variety was treated as ordered. The germination for the treated seed was only 80% while the remaining non-treated seed had 90% germination. In a spring with extremely wet soils,…

Remember, the penalty from “side wall” compaction is significantly greater than the penalty for late planting. Until the 3rd week of May (20 May 2013), the corn yield losses are small for this delayed planting.
The morning soil temperatures at the Agronology 10 Research Center were generally better than I had expected. A…

Think about your corn production on your personal farming operation as the most important factor for you to consider. Yes, price per bushel at selling time is significant, but total bushels to be sold are something you can influence. Those management practices that can enhance your potential yields need to be done correctly. Yes,…
