It was hard to believe that mollusks could be the cause of this damage, especially when the area has been experiencing a drought period and warmer temperatures; however, they were.

If possible, let the corn get through pollination. Corn ears with less than 400 kernels per ear likely have yield loss. Corn with 300 kernels or less will likely have yield losses that trigger crop insurance.

Immature individuals (known as nymphs) of short-horned grasshoppers have been observed feeding on full-season and double-crop soybeans in Lyon and Caldwell counties. Populations of these insects seem to be increasing, and damage is already present.

As we near harvest, one concern to keep in mind would be the effect of higher than normal temperatures during grain fill that the majority of the wheat-producing areas of our state have experienced this year.

Corn plants with thrips were observed in fields near the Cumberland River in Livingston County during the last week of May but as usual, rainfalls reduced thrip populations.

Kentucky soybean planting is quickly wrapping up and the majority of corn has or is receiving a postemergence herbicide application as it quickly advances in growth stages.

The last time Kentucky had temperatures this extreme prior to wheat harvest was in 2018 (Table 1). That year, the average yield for the state was 66 bu/A. As a result of the sudden increase in temperature, test weights were reduced and wheat dried down significantly faster than normal. In contrast, 2021 had an almost ideal grain fill period, which resulted in a record-setting state average of 87 bu/A.

The University of Kentucky Research and Education Center in Princeton, Kentucky, destroyed by a December tornado, moved closer to reconstruction today when the UK Board of Trustees approved a $38 million project for the main building.

The current heat wave is expected to last until the end of June. There are some low chances of rain scattered in the forecasts. We need to start watching water use in corn across the state. The next two weeks could provide us with some strong indicators on expected corn yields this fall.

As wheat harvest approaches, now is a good time to consider drying and storage options. A good place to start is by reviewing the equilibrium moisture content chart for soft red winter wheat below, which shows the limits of drying, as well as storage, over a range of average weather conditions in Kentucky throughout the year.

The Week #16 corn planting progress was only 10%, but corn planting progress reports from 2001 to 2021 show very little correlation between planting progress and yield.

Corn planting in 2022 is off pace from the five-year average for Kentucky with only 6% planted on the April 17 report. The calendar says we could have started planting corn April 1 in western Kentucky and April 15 in central and eastern Kentucky. The calendar suggests that we are behind. The weather and soil conditions suggest we are not.

Even though we have officially made it to spring in Kentucky, we are not exempt from sub-freezing temperatures. From March 26 through March 28, large portions of the state experienced temperatures that lingered around the threshold that could significantly impact wheat yields.

Have your manure tested to know its value. Whether you are buying, selling, or using manure generated on your farm, you need to analyze samples that represent what you will spread. This allows the manure to be applied at the appropriate rate for the field.

In times of high commodity prices and with increasing crop yield potentials it becomes even more critical to obtain maximum economic returns by protecting crop yield from potential losses caused by weeds interfering with crop production.
