Corn Planting Kicks Off in Tennessee

Author:  Comments Off on Corn Planting Kicks Off in Tennessee

Gentlemen, start your planters!  We have a little corn in the ground this week.  Rain kept most folks from planting corn extremely early, and that may turn out to be a good thing if April weather becomes as volatile as we know it can be.  Weather conditions look favorable for planting next week— with mostly dry and mild temps after this next system passes through.  We are not “too early” at this point and I hope that folks with several acres ahead of them will be able to at least start planting corn during the last week in March.  Continue reading


Fungicides on Late Corn

Author:  Comments Off on Fungicides on Late Corn

Corn fungicides have been going on a good number of acres in areas that have aerial application options.  We have more May planted corn this season that is tasseling now and pretty good soil moisture.  We typically have more disease pressure in May planted corn although reports of Gray Leaf Spot and other diseases have been sporadic in rotated ground.  A better return on your money is most likely where some disease is evident, yield potential is decent and the hybrid has shown more of a response to a fungicide based on field testing.  Continue reading


Soybean Inoculants…The Other Seed Treatment

UT’s standard recommendation is to include an inoculant where soybeans will be planted into fields that have never been planted to soybean or where soybean has not been grown in the field in the past 3 to 5 years.  There are several products on the market that contain a single or even multiple strains of Rhizobium bacteria designed to improve root nodulation and help soybean roots fix nitrogen from the atmosphere into a usable form for the plant.  Since the soybean must make 50 to 75% of its required nitrogen through this process this is pretty important stuff.  With the hectic weather this spring creating flooding and instances where lime was not applied timely folks should include an inoculant in the following situations: Continue reading


Corn RM and Planting Late

Author:  Comments Off on Corn RM and Planting Late

Tennessee has a long enough growing season that any Early, Medium or Full relative maturity hybrid planted well into May will have enough heat units to make a corn crop.  As a group, full season hybrids tend to have more ‘southern genetics’ which includes improved tolerance to heat compared to short season hybrids and they are considered first for late planting.  However, a big negative for some producers may be the delay in harvest that comes with full hybrids compared to earlier maturity hybrids.

Making Adjustments for Late Planted Corn

Those who aren’t dealing with floodwater are out looking at fields this afternoon to figure out how quickly we can get the planters back in the field.  This article is written for those who intend to continue planting corn to fill contracts or to attempt to stay in their planned rotations.  We have to assume some yield reduction now compared to what “might have been” but yield penalty will depend so much on our weather this summer it is difficult to predict an amount.  I do think there is benefit to planting as much corn as quickly as possible over the next week.  Some field work and experience also tells us that managing late planted corn will be slightly different compared to a March or April planted crop.   Continue reading
