Is it better in the bag or in the field?

It is hard to be patient at this time of year. We all know that the sooner we can get started planted the better or is it? Yes and only if the conditions are right for quick emergence is this true. It takes approximately 100 – 150 CHU to emerge corn and with the daytime temperatures to date we have accumulated nothing in the way of heat units. If you have corn planted you are playing the waiting game to see when (if?) it is going to emerge. With our current genetics, quality standards and seed treatments seed can survive delayed emergence significantly better than 10 – 15 years ago, but if three to four weeks go by and we still have not seen the corn it will be hard to be patient and wish that you left it in the bag. So what should you do? Plant as soon as the soil is fit.

Should I start changing my hybrids to lower heat units? No. Prior to May 10, Syngenta Agronomy Research shows only a one bushel (or 0.11 bu/day) of corn yield loss with a ten day delay in planting. If you did not get finished planting until May 7th this year compared to April 28th last your expected yield loss is one bushel per acre. What about after May 10th? You may want to consider switching your very long heat unit corn to a shorter day hybrid and plant the rest. Our research has shown a one bushel per day for every day of delayed planting. What about May 24th? This topic will be discussed if delay occurs.

In the meantime we need to practice patience. Our elders were correct – patience is a virtue.
