Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.

Kentucky is in the upper transition zone which allows for the growth of warm- and cool-season forages. Corn, a warm season grass, grows well in the state and may be harvested for either grain or silage. Corn harvested as silage can be an economical alternative for beef cattle. Implementing sound management strategies and determining the nutrient content to balance rations will allow for successful feeding of corn silage to beef cattle.

A cover crop is a plant species that is grown between cash crops primarily to provide cropping system services rather than to produce a harvestable product. Services provided by cover crops include soil health improvement, soil conservation, nutrient release and capture, and weed suppression. However, like any management practice, cover crops also have challenges and limitations. This publication is intended to provide an overview of cover crop use in Kentucky and the challenges and benefits of this practice.

Soybean seed quality is very important for crop establishment. In general, seed quality is an indicator of a seed's ability to produce a seedling in field conditions and includes both seed germination and seed vigor. Most producers are familiar with seed germination since they have seen it on a seed tag. Fewer are familiar with seed vigor.

The soft red winter wheat grown in Kentucky is the fourth most valuable cash crop in the state. Winter wheat has been an integral part of crop rotation for Kentucky farmers. Wheat is normally harvested in June in Kentucky and provides an important source of cash flow during the summer months.

Grain sorghum can be used for a variety of purposes including animal feed, unleavened breads, cakes, wallboard, starch, dextrose, brooms, ethanol, high quality wax, and alcoholic beverages. Grain sorghum produced in Kentucky is most commonly used for animal feed and was first grown here in the 1920s. Although acreage in Kentucky has fluctuated considerably over the years, yields have generally exceeded the national average since the 1970s, indicating that grain sorghum is an option for producers interested in diversifying grain crop operations.

Hybrids were evaluated for silage performance on cooperating farms. Representatives from seed companies submitted hybrids of their choosing. University of Kentucky personnel or third-party contractors planted the hybrid seeds. Farmers applied the soil fertility and pest management. University of Kentucky personnel harvested, weighed, chopped, and packaged corn for quality analysis. University personnel conducted the statistical analyses and final reporting of hybrid performance.

The number of organic dairy cows in Kentucky has been steadily increasing for years, yet there's not enough organic corn produced in the state to feed the growing herds. In short, a new market has developed in the state, but few local farmers are taking advantage of it. While Kentucky farmers are no strangers to corn, growing corn organically utilizes different management, cultural and marketing practices and requires new skills. And, importantly, organic production must follow an approved farm plan that allows farmers to sell their corn as certified organic. This publication is designed to be both an introduction to a new enterprise as well as a practical manual for those interested in pursuing organic corn production on their own farms.

Soft red winter wheat is one of the major row crops in Kentucky, along with corn and soybean. Climate change and variability have the potential to significantly impact this important economic enterprise within our state. Perhaps no year in recent history has seen as dramatic a negative impact of weather on annual crop yields as 2012. Kentucky experienced above normal temperatures during late winter and early spring that advanced wheat growth beyond normal levels. The warm weather was followed by a late spring freeze that severely damaged wheat yields. Following the late freeze, above normal spring temperatures encouraged farmers to plant corn early and most of the crop had an excellent start to the season. However, spring was followed by some of the hottest and driest weather in 50 to 70 years, depending on the location in Kentucky, and corn yields were devastated. Conversely, 2013 was relatively wet and cooler for most of the wheat, corn and soybean growing season, resulting in excellent yields of all three crops.

Soybean variety selection is one of the most important and most difficult management decisions a producer must make each year. It takes careful identification of the problems and needs of the production system. When done properly it increases the chance the variety will reach its full yield potential while eliminating costs for unnecessary traits, resulting in highly profitable returns.

The 2012 Soybean Management Verification Program (SoyMVP) enrolled 19 fields across Western Kentucky, providing ten direct comparisons between University of Kentucky recommendations and producers practices for soybean production. All fields were scouted weekly and recommendations were made on the university portion of the field based on established thresholds and observations from agronomic research. The objective of these comparisons is to validate university research and identify areas for more research.

The Corn and Soybean Production Calendar was developed to help producers prioritize and schedule work events in a timely fashion on the farm. Weather events and equipment breakdowns rarely follow an organized schedule. However, if other practices within the farming operation are prioritized, perhaps a producer can better address the emergencies that will occur.

Hail is precipitation in the form of irregular shapes of ice. Hail can shred leaves off corn plants, bruise stalks, and turn a beautiful field of corn into bare stalks with a few ragged leaves. The initial sight of hail damage is sickening to any farmer. Small corn, with the growing point below the soil surface (see corn staging below) is highly tolerant to hail damage. As the growing point moves above the soil surface and the corn plant gets closer to tasseling, corn becomes more susceptible to hail damage. Corn is most susceptible to hail damage from the period just prior to tasseling through early milk. Once corn passes the early milk stage, it becomes more tolerant to hail damage.

Evaluating damaged corn stands and determining when to replant is often a difficult task. Survival, health, and expected yield of the current stand must be weighed against replanting costs, additional management, and expected yield of a replanted crop. The options are rarely clear-cut because damaged corn is rarely uniform throughout the field. The following information will help when making evaluations and management decisions.

Estimating soybean yield while the crop is still standing in the field can be a challenging procedure. Proceed with caution since variability in yield components such as plant population, seeds per pod, and seed size can all drastically affect the final yield. Yield estimates may be inaccurate when conducted before seed fill is complete, and assumptions of final pod number, seeds per pod, and seed size may not accurately reflect those values at maturity. The best estimate can be achieved at reproductive growth stage R6 (green pods with seeds that fill the pod cavity) or later.
