The Seed: An essential component of yield production
By Dennis Egli

We grow grain crops for their seeds, so it makes sense that we should give some thought to how seeds grow. After all, the production of yield is not just about leaves and photosynthesis, seeds are also important.
A wet spring and dry summer make for wild yield swings

Most of the regions in Kentucky growing corn and soybeans received between 40 to 51 inches of rain by the first week of July. Most of those same regions have received very little or scattered rains since.
Avoiding Lodged Corn

Corn harvest is well underway in western Kentucky, but as the rest of the state begins to harvest, farmers need to be aware of potential lodging issues. Pockets of fields scouted across the state show pre-harvest lodging and/or stalk strength tests have indicated a high potential for lodging to occur (Figure 1).
Well-Filled Ears and High Corn Yields

We’ve all seen advertisements for corn hybrids that show a row of corn with an ear on every plant that is filled to the tip. The implication is that well-filled ears are an indication of high yield.
Corn is Demanding a Lot of Water and Our Soils Should Have It

According to the July 6, 2025 USDA Crop Progress Report, 40% of corn in Kentucky had reached silking and 4% had reached the dough stage. From the earliest appearance of tassels until pollination is complete corn demands the most water and is the most sensitive to a lack of water.
Time and Crop Productivity

Time is an important resource. We never seem to have enough, and it often passes too fast. But the truth is, we don’t often think about time when we think about crop productivity.

Photosynthesis – The Ultimate Yield Producer
By Dennis Egli
Published on Jun. 13, 2025
The keys to high yield include variety selection, planting date, population, fertilizer and control of weeds and pests. Photosynthesis doesn’t make the list, but there is no yield without photosynthesis. High yield requires high photosynthesis.
Timing is Key – Describing the Critical Stages of Yield Production
By Dennis Egli
Published on May. 19, 2025
The effect of management practices or stress on corn and soybean yields often depends upon when it happens. It’s not just how dry it is or how hot it is, but when it’s hot or dry. ‘When’ refers to what the crop is doing. As with most things in life – timing is all important.
