Many producers have finished planting corn and stands are surprisingly decent considering the year. The earliest planted corn is around V-5 stage and due for layby N. There were a few replant calls coming in this week. The heavy rains during the early part of May followed by very cold weather caused some stand issues in a few fields particularly in northern tier counties, including a type of injury related to weather that we don’t normally see a lot of.

We still have miles to go before all of our corn is in the ground, but some folks are turning to planting soybeans this week. Some acres are behind Leadoff in the burndown program. Leadoff at 1.5 ounces of product per acre has a 30 day plant back to soybeans. In most years, 30 days along with some rain is enough time for the material to break down in the soil and not cause injury to soybeans. In 2013, root and plant stunting were observed in soybeans planted at the correct time following Leadoff and this was attributed to an overall cool wet environment causing slower breakdown of rimsulfuron in the soil. Symptoms were not seen in STS (sulfonylurea tolerant) varieties planted at the same time. Bottom line, this spring with cooler and wet soil conditions, expect Leadoff breakdown to be slower and unless varieties are sulfonylurea tolerant there may be some stunting observed in non-STS varieties planted early or inside the 30 day window, particularly in end rows and areas where spray overlap occurred.
Soil temperatures are still running below 50 degrees and while there is a little corn planted in a few places, most folks are waiting for slightly warmer weather to begin planting corn. Corn sits still below 50 degrees and germination and emergence will take several days at current soil temps. Tennessee March weather is finicky and even though we can make decent corn by planting in March, every year is going to be different. This year is just not allowing us to get a very early start. Fortunately, our weekend and next week’s forecast look decent to start getting seed in the ground where it is dry enough, and this will allow us to have some early planted corn in 2014.
Tennessee’s recommended wheat planting window (Oct 15-Nov 10) is right around the corner. The following are a few reminders that may help us achieve a decent stand going into this fall. Continue reading

Early April planted corn is nearing black layer. Ear condition is decent for the most part, but we are seeing some sprouting on ears where hybrids have short, loose husks and some ears with diplodia or other molds. At this point, the best remedy to maintain ear quality is dry weather since ears are all turned upwards on plants. Yield potential is excellent in many areas around the state and should make for some interesting pre-harvest yield estimates. Continue reading
No one is knocking the rain because we were all needing a shower, but rains have halted wheat harvest and the planting of remaining soybean acres. Yield potential tends to be reduced for July planted beans because of the compressed growing season. Weather over the next few months will play a huge role in determining how successful our late planted crop will turn out unless irrigation is an option. Continue reading
High yield and abundant straw have gone hand-in-hand this year. Heavy lodging in some fields has left surface residue that is wet underneath and impossible to plant through, causing a number of wheat fields to be burned for residue management. Continue reading
