Post Tassel – Corn


After the corn has tasseled for approximately 7 to 10 days, significant yield indicators are quite obvious.  On the individual ear, the girth (rows) around the ear can be counted.  Next, the number of ovules pollinated down the length of the ear can be counted.  The pollinated ovules will be rectangular shaped, and will later develop a pinkish color.  Then, make a determination on the number of pollinated ovules which could develop into kernels.  Finally, count the number of productive ears per .001A.


My observations on this year’s corn crop:

 


  1. Wide yield variations in short distances

  2. Multiple stress are significantly reducing yield

  3. Early planted, high fertility corn looks good

  4. The amount of rain received around the 4th of July is critical
