An Example Of An Outreach Program For Horse Pasture Management And Education, Krista L. Lea, S. Ray Smith
An Example Of An Outreach Program For Horse Pasture Management And Education, Krista L. Lea, S. Ray Smith
IGC Proceedings (1997-2023)
Kentucky boasts over 30,000 horse farms that house over 200,000 horses. The University of Kentucky Horse Pasture Evaluation Program began in 2005 to assist horse owners and managers in improving pasture quality and quantity. This program collects detailed botanical composition and tall fescue analysis to provide horse owners and managers with a comprehensive picture of pasture composition and field by field recommendations on management practices that will improve each pasture. Samples of tall fescue are also collected and analysed for endophyte presence and ergovaline concentration to evaluate tall fescue toxicity risk. Management recommendations include tall fescue mitigation or elimination strategies. …

A Comparison Of Four Methods Of Botanical Analysis In Kentucky Cattle Pastures, Echo Elizabeth Gotsick, S. Ray Smith, Jimmy C. Henning, Christopher D. Teutsch
IGC Proceedings (1997-2023)
Throughout the many decades of grassland and forage research, practitioners have used many different methods to assess botanical composition. While a few of these methods have proven to be accurate and efficient, there has been limited direct comparison between methods. The objective of this study was to determine an accurate and efficient method to determine botanical composition for researchers, practitioners, and students. Six farms with two pastures each were monitored across the state of Kentucky. Sampling started fall 2020 and continued through fall 2022 with measurements taken three times a year using the following measurement techniques: step point, visual estimation, …
Effects Of Bacillus Mycoides Supplement In A Reduced Frequency Fungicide Program On Chambourcin Grapevines (Vitis Vinifera L.), Ryan Alan Mairs
Effects Of Bacillus Mycoides Supplement In A Reduced Frequency Fungicide Program On Chambourcin Grapevines (Vitis Vinifera L.), Ryan Alan Mairs
Masters Theses & Specialist Projects
Fungal diseases pose significant challenges for grapevine producers in Kentucky due to the region’s abundant moisture and relative humidity. Methods to reduce fungicide application frequency would prove both economically and temporally valuable to producers. A field experiment was established in Bowling Green, KY in 2017 to investigate Bacillus mycoides isolate J (LifeGard) as a supplement to a fungicide program for systemic acquired resistance (SAR). Three fungicide treatment regimens were implemented consisting of a program modelled from the Midwest Fruit Pest Management Guide (2017) and an identical program supplemented with 140 g ha-1 LifeGard per application (both applied on 14 day …

2002-2003 Kentucky Canola Variety Performance Test, Greg Schwab, Lloyd W. Murdock, James H. Herbek, Chad Lee, David Van Sanford
2002-2003 Kentucky Canola Variety Performance Test, Greg Schwab, Lloyd W. Murdock, James H. Herbek, Chad Lee, David Van Sanford
Agronomy Notes
Winter canola is a crop that is well suited for Kentucky’s climate and crop rotation, but production peaked at 20,000 acres in 1989and has since declined mainly due to winter hardiness concerns. Changes in the 2002 farm bill have once again caused farmers to consider converting some of their wheat acreage to canola production. For the past several years, plant breeders have been working to improve canola’s winter hardiness and have released several varieties that seem to be better suited for Kentucky’s variable winters than the varieties grown in the late 1980s. A study was initiated in the fall of …
Phosphorus Soil Test Change Following The Addition Of Phosphorus Fertilizer To 16 Kentucky Soils, William O. Thom, James E. Dollarhide
Phosphorus Soil Test Change Following The Addition Of Phosphorus Fertilizer To 16 Kentucky Soils, William O. Thom, James E. Dollarhide
Agronomy Notes
When applying phosphorus to soils it is important to know how much the soil test P changes with the addition of various rates. Soils are different in how they respond to varying rates of application, and only limited information is available for Kentucky soils.
Zinc Fertilizer Rates And Mehlich Iii Soil Test Levels For Corn, Lloyd W. Murdock, Paula L. Howe
Zinc Fertilizer Rates And Mehlich Iii Soil Test Levels For Corn, Lloyd W. Murdock, Paula L. Howe
Agronomy Notes
Zinc (Zn) is the micronutrient most often deficient for corn in Kentucky. This problem occurs every year but is more commonly seen in years with a cool, wet spring. Although the environment, soil type and past erosion each have an effect, the most important factors controlling plant available Zn are the soil pH, extractable soil phosphorus (P) and extractable soil Zn. While the amount of Zn in the plant increases as the available soil Zn increases, increasing levels of soil P and pH are strongly associated with reduced levels of Zn in the plant.
The Effect Of Drying Soil Samples On Soil Test Potassium Values, Kenneth L. Wells, James E. Dollarhide
The Effect Of Drying Soil Samples On Soil Test Potassium Values, Kenneth L. Wells, James E. Dollarhide
Agronomy Notes
Extreme temporal and spatial variability of soil test potassium values (STK) was measured on small plots (12-ft x 40-ft) being used for a STK correlation and calibration study on a Crider soil in Larue County, Kentucky. Twelve periodic samplings of the 20 small plots in this study over a period of 18 months showed as much as two-fold temporal differences in STK within individual plots, many of which had received no potassium (K) fertilizer during the study. Spatial variability of STK also varied as much as two-fold among the individual small plots at any given sampling time for similar treatments. …
Trends In Alfalfa Production And The Beef And Dairy Industries In Kentucky During 1989-98, Dennis Hancock, Michael Collins
Trends In Alfalfa Production And The Beef And Dairy Industries In Kentucky During 1989-98, Dennis Hancock, Michael Collins
Agronomy Notes
On suitable soils, alfalfa produces the highest yield of nutrients possible from a perennial forage crop. However, high production costs and restrictive soil requirements have limited the production of alfalfa in Kentucky. High producing dairy cows respond well to premium quality forage, so alfalfa is a preferred forage crop in dairy production. Thus, alfalfa production is primarily contingent on the producer’s method of marketing the crop.
Comparison Of Weed Management Strategies With Roundup Ready® Corn, J. A. Ferrell, William W. Witt
Comparison Of Weed Management Strategies With Roundup Ready® Corn, J. A. Ferrell, William W. Witt
Agronomy Notes
Corn weed management during the past several years in Kentucky has centered around two herbicide families, the chloroacetamides (Dual, Frontier, Harness, Micro-Tech, Surpass) and the s-triazines (AAtrex, Bladex, Princep). These products have been used widely because they offer acceptable, full season control of many common warm season annual weeds at a reasonable price. This combination has been so popular that several premixtures that contain these types of herbicides (Bicep II, Bullet, Guardsman, Harness Xtra, Surpass 100, FulTime) are used commonly used in Kentucky. The key to this efficacious and economic program is atrazine because it controls most annual broadleaf …
Small Scale Temporal And Spatial Variability Of Potassium Soil Test Values On A Crider Soil, Kenneth L. Wells, James E. Dollarhide, Frank J. Sikora
Small Scale Temporal And Spatial Variability Of Potassium Soil Test Values On A Crider Soil, Kenneth L. Wells, James E. Dollarhide, Frank J. Sikora
Agronomy Notes
An on-farm, small plot study conducted in 1996, on a Crider soil in Larue County, Kentucky, resulted in unanticipated wide variability of soil test potassium (STK) values between spring and fall sampling. Because of this, the small plots were sampled monthly over a period of time with the objective of determining if such variability in STK values was real.
Do Cover Crop Residue And No-Till Increase Poultry Litter Runoff?, M. A. Cooprider, Mark S. Coyne
Do Cover Crop Residue And No-Till Increase Poultry Litter Runoff?, M. A. Cooprider, Mark S. Coyne
Agronomy Notes
Manure and litter produced during broiler production are an environmental issue in Kentucky. The most common and practical disposal method is to apply the poultry wastes to pasture and crop land. If the wastes are incorporated by tillage immediately after application to crop land, nitrogen that might otherwise be lost by ammonia volatilization is conserved. However, incorporating wastes is not possible in no-till, which is a best management practice (BMP) used by 51% of Kentucky's farmers to control soil erosion. One question is whether surface application of poultry wastes onto no-till fields could increase fecal bacteria contamination of surrounding waterways …
Early Maturing Varieties And Soybean Cyst Nematodes: Will This Marriage Work?, Colleen C. Steele, Larry J. Grabau
Early Maturing Varieties And Soybean Cyst Nematodes: Will This Marriage Work?, Colleen C. Steele, Larry J. Grabau
Agronomy Notes
Soybean cyst nematode (SCN) is widely distributed in Kentucky’s soybean growing areas. The use of SCN-resistant varieties has long been a recommended production practice for infested fields. However, continuous use of such varieties can result in a shift to a race of SCN which is able to vigorously attack previously resistant varieties. For this reason, many states recommend that producers periodically grow a crop of SCN-susceptible soybeans within a crop rotation when SCN populations are at minimal levels (causing less than a 5% loss in yield). The UK Plant Pathology Department recommends a four year rotation in SCN-infested fields [PPA3; …

However, continuous use of such varieties can result in a shift to a race of SCN which is able to vigorously attack previously resistant varieties. For his reason, many states have long recommended that producers periodically grow a crop of SCN-susceptible soybeans within a crop rotation when SCN populations are too low to cause yield reductions. In Kentucky, the UK Plant Pathology Department recommends a four year rotation in SCN-infested fields [PPA3; "Wanted: …

Kentucky County Soil Sample Summaries, Vern Case
Agronomy Notes
The UK Soil Testing Labs at Lexington and Princeton, KY test 50,000 to 60,000 soil samples each year. Samples are submitted through the county Extension offices for agronomic (Ag) crops, commercial horticulture, home garden/lawn, greenhouse media, and surface mining reclamation. The Mehlich III extractant (M-3) is used for routine determination of phosphorus (P), potassium (K),calcium (Ca), magnesium (Mg) and zinc (Zn). Amounts of these nutrients extracted are determined by either ICP methodology or by color for P and atomic absorption for K, Ca, Mg and Zn. Soil pH is determined on a 1:1 soil:water mix using appropriate electrodes and pH …
An Evaluation Of Twelve Maturity Group Ii Soybean Varieties At Lexington, Kentucky, Larry J. Grabau, Colleen C. Steele
An Evaluation Of Twelve Maturity Group Ii Soybean Varieties At Lexington, Kentucky, Larry J. Grabau, Colleen C. Steele
Agronomy Notes
In both 1993 and 1994, the Kentucky Soybean Promotion Board funded an on-farm test of a small set of Maturity Group (MG) II varieties. Those studies showed that several MG II varieties were competitive with a high-yielding MG IV variety. However, other MG II varieties did not perform as well in those tests, indicating that variety selection is an important management consideration if this early maturing cropping system is to be successful in Kentucky soybean producers' fields. MG II varieties used in past University of Kentucky tests have been chosen based on their performance in university variety trials where such …
Grain Quality Of Early Maturing Soybean Grown In Kentucky, M. V. Kane, Colleen C. Steele, Larry J. Grabau, C. T. Mackown, David F. Hildebrand
Grain Quality Of Early Maturing Soybean Grown In Kentucky, M. V. Kane, Colleen C. Steele, Larry J. Grabau, C. T. Mackown, David F. Hildebrand
Agronomy Notes
Interest in grain quality of US soybean has grown in recent years. For example, in 1990, there was much interest in "component pricing" of soybean grain, Under that plan, growers would be paid a price for their grain that reflected the value of the protein and oil it actually contained, rather than the common price paid to all growers, regardless of any variation in protein and oil content. However, the soybean processing industry is evidently not excited about the complexity of testing individual lots for protein and oil and keeping track of pricing structures depending on those results. As a …
Lime Source And Rate Effects On Corn Production On An Acid Soil, Kenneth L. Wells, James E. Dollarhide, V. W. Case
Lime Source And Rate Effects On Corn Production On An Acid Soil, Kenneth L. Wells, James E. Dollarhide, V. W. Case
Agronomy Notes
Quality of lime available for use in neutralizing soil acidity can be quite variable in Kentucky. This sometimes raises questions of which locally available source is most effective. Information about the quality of individual lime sources is necessary to make such determinations.
An Evaluation Of Twelve Maturity Group Ii Soybean Varieties At Lexington, Kentucky, Larry J. Grabau, Colleen C. Steele
An Evaluation Of Twelve Maturity Group Ii Soybean Varieties At Lexington, Kentucky, Larry J. Grabau, Colleen C. Steele
Agronomy Notes
In 1993, an on-farm study funded. by the Kentucky Soybean Promotion Board showed that the best Maturity Group (MG) II variety tested was quite competitive with the best available MG IV variety. However, other MG II varieties did not fare as well, indicating that careful variety selection will be essential for on-farm success with this MG II cropping system. MG II varieties used in past University of Kentucky tests have been chosen based on their performance in university variety trials where they are normally grown, for example, in Iowa, Illinois, Indiana, and Ohio. Such tests include relatively large numbers of …
Crude Protein Of Hybrid Corn Varieties Evaluated In The Kentucky Hybrid Corn Performance Tests From 1990 To 1993, C. G. Poneleit, K. O. Evans, Michael Collins, Gary L. Cromwell
Crude Protein Of Hybrid Corn Varieties Evaluated In The Kentucky Hybrid Corn Performance Tests From 1990 To 1993, C. G. Poneleit, K. O. Evans, Michael Collins, Gary L. Cromwell
Agronomy Notes
Grain samples have been collected each year since 1990 from three locations of the Kentucky Hybrid Corn Performance Test and analyzed for crude protein. The objective was to provide an unbiased comparative evaluation of the crude protein content of corn hybrids sold in Kentucky. The results indicate that while management and environment at each test 1ocat i on may have significant influences, crude protein does differ among hybrid genotypes. The feeding value of specific hybrid genotypes based on their protein content may have significant influence in diet formulation for non-ruminant animals owing to the amount of supplement needed to properly …
