A Perplexing Process: Understanding How Agricultural Producers Process Best Management Practice Information, Audrey E. H. King, Lauri M. Baker Nov 2018

A Perplexing Process: Understanding How Agricultural Producers Process Best Management Practice Information, Audrey E. H. King, Lauri M. Baker

Journal of Applied Communications

Best management practices (BMPs) are suggested practices that help agricultural producers optimize production while reducing pollution, soil erosion, and other environmental impacts. Many audiences, including scientists and policy makers, have expressed disappointment at the current level of BMP use. Elaboration likelihood model (ELM) is used to understand how people process messages. ELM states that people can process messages either centrally or peripherally. This study sought to understand how producers processed information related to BMP adoption in grazing systems. Researchers conducted qualitative, in-depth interviews with 42 beef-cattle producers in Kansas and Oklahoma. It was found producers process information both centrally and ...

Agricultural Communications Students Describe A Short-Term Field Experience, Angel N. Riggs, Diane Montgomery

Journal of Applied Communications

Student-run publications, including newsrooms and similar agency-style work achieve the curricular goal of experiential learning (Roberts, 2006) for university agricultural communication students. Gaining a journalistic skillset in the classroom is richly supplemented with experiencing real-world and authentic agency immersion to reveal to students the genuine characteristics of a workplace. The purpose of this study was to use Q methodology to evaluate a real-world, out-of-class-but-supervised newsroom producing publications for the State FFA Convention. Fifteen undergraduate students who were immersed in this three-day program in which students publish original work to disseminate information to FFA participants and the public participated in the ...


Understanding Consumer Intent To Buy Local Food: Adding Consumer Past Experience And Moral Obligation Toward Buying Local Blueberries In Florida Within The Theory Of Planned Behavior, Jessica Holt, Joy N. Rumble, Ricky Telg, Alexa Lamm Jun 2018

Understanding Consumer Intent To Buy Local Food: Adding Consumer Past Experience And Moral Obligation Toward Buying Local Blueberries In Florida Within The Theory Of Planned Behavior, Jessica Holt, Joy N. Rumble, Ricky Telg, Alexa Lamm

Journal of Applied Communications

Buying local food has become an increasingly popular way for consumers to engage with those who grow their food; however, research has shown a specific audience tends to buy local food due to individual-specific barriers. To better understand what motivates consumers to buy local food the Theory of Planned Behavior was used as a way to potentially predict consumers’ behavior toward buying locally grown blueberries. Also, the variables of past experience and self-identity/moral obligation toward buying local food were introduced to the model since both variables may increase the predictability of the Theory of Planned Behavior model in certain ...

Safely Through The Gate: Exploring Media Coverage And Journalists Decisions On The Flow Of Farm Safety Stories, Rebecca Swenson, Brandon Roiger, Alexis Murillo

Journal of Applied Communications

Agriculture continues to rank as one of the most dangerous industries in the nation. Media coverage is an important tool for sharing farm safety information, improving knowledge and changing behaviors. Despite this importance, surprisingly little research has focused on agricultural media coverage and the forces that influence journalists’ decisions about when and how to cover safety stories. This study uses content analysis methods to examine the nature of farm safety issues, accidents, and topics that appear in mainstream news, agricultural media, and blogs. Researchers also interviewed journalists and bloggers to better understand their motivations, barriers, and information needs when covering ...

Media Portrayal Of Gm Science And Citrus Greening In State And National Newspapers, Jeremy D'Angelo, Jason D. Ellis Ph.D., Katherine Burke Ph.D., Taylor Ruth

Journal of Applied Communications

Huanglongbing (HLB), commonly known as citrus greening, is a bacterial disease severely affecting the profitability and continuation of the citrus industry in Florida and is threatening the citrus industry in other states as well. Currently, the disease only can be managed, not cured. Gene-based therapies, such as GM science, have been identified as a viable long-term solution. However, consumer acceptance of genetically modified food is low and their understanding and acceptance of new technologies is largely dependent on what they receive through mass media. Therefore, the purpose of this research is to understand news coverage of both citrus greening and ...

Effect Of Late Nitrogen Applications On Grain Filling In Corn, J. A. Fernandez, I. A. Ciampitti Jan 2018

Effect Of Late Nitrogen Applications On Grain Filling In Corn, J. A. Fernandez, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

In order to evaluate the effect of nitrogen (N) with late-season fertilizer applications in corn, grain yield and grain filling parameters were evaluated for three genotypes under three N levels. Hybrids with different release years (3394, 1990s; P1151, 2000s; and P1197, 2016) and contrasting N application scenarios (zero-N, N at flowering, and N two weeks after flowering) were evaluated in two studies (dryland and irrigated) at the Ashland Bottoms Research Farm, Manhattan, KS, 2017 season. Results showed that under N stress conditions, the absence of N fertilization in corn significantly reduced yields, by affecting both grain number (GN) and grain ...


Effect Of Fungicides On Southern Rust Of Corn, E. A. Adee, S. Duncan Jan 2018

Effect Of Fungicides On Southern Rust Of Corn, E. A. Adee, S. Duncan

Kansas Agricultural Experiment Station Research Reports

The decision to apply fungicides to corn is not an easy decision in Kansas, especially when grain prices are low. Numerous factors determine what diseases are present, and whether the plants will be defoliated enough to reduce yield. Correctly identifying the disease, knowing what environmental conditions favor the development of an epidemic, and knowing the hybrid’s resistance to the diseases can be known before making the decision. However, knowing if the conditions will be favorable for the spread of the disease up the plant is very unpredictable. A situation like a ‘perfect storm’ for foliar diseases defoliating corn occurred ...


High Yielding Soybean: Genetic Gain And Nitrogen Limitation, O. A. Ortez, F. Salvagiotti, J. M. Enrico, E. A. Adee, I. A. Ciampitti Jan 2018

High Yielding Soybean: Genetic Gain And Nitrogen Limitation, O. A. Ortez, F. Salvagiotti, J. M. Enrico, E. A. Adee, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

The United States and Argentina account for more than 50% of the global soybean production. Closing yield gaps (actual on-farm yield vs. genetic yield potential) would require an improvement in the use of the available resources. Overall, 50-60% of soybean nitrogen (N) demand is usually met by the biological nitrogen fixation (BNF) process. A scientific knowledge gap still exists related to the ability of the BNF process to satisfy soybean N demand at varying yield levels. The overall objective of this project is to study the contribution of N via utilization of varying N strategies under historical and modern soybean ...

Gonadotropin-Releasing Hormone Increased Pregnancy In Suckled Beef Cows Not Detected In Estrus And Subjected To A Split-Time Artificial Insemination Program, S. L. Hill, D. M. Grieger, K C. Olson, J. R. Jaeger, K. R. Harmoney, C. R. Dahlen, M. R. Crosswhite, N. Negrin Pereira, S. R. Underdahl, B. W. Neville, J. Ahola, M. C. Fischer, G E. Seidel, J. Stevenson

Kansas Agricultural Experiment Station Research Reports

Estrus-synchronization programs allow insemination of all females in a herd at one fixed time on the first day of the breeding season. Inseminating cows after they have expressed estrus increases pregnancy rate (PR) compared with cows that do not display estrus in a timed AI (TAI) program. Identification of estrus status can be facilitated by using estrus-detection patches. Varying AI timing according to estrus status has increased PR in some previous studies. Reducing the number of injections in a TAI program decreases labor requirements, stress on cows, and overall cost of the program. Previous studies have demonstrated that PR is ...


Using Modified Intensive Early Stocking For Grazing Replacement Heifers, K. R. Harmoney, J. R. Jaeger Jan 2018

Using Modified Intensive Early Stocking For Grazing Replacement Heifers, K. R. Harmoney, J. R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Even though Kansas native rangelands often have steep slopes or shallow soils not conducive to many other uses other than livestock grazing, native rangeland and peren­nial grassland acres in Kansas have been declining. Cropland acreage over this same time frame has increased, and so has rangeland fragmentation into small ranchettes and urbanization. Producers may be looking to increase production efficiency on a shrink­ing forage land base. The use of intensive early stocking (IES) is one the most efficient stocking strategies to produce beef on rangeland acres. The IES strategy has been widely used in eastern Kansas and is ...


Can Modified Intensive Early Stocking Be Used In Cow/Calf Production?, K. R. Harmoney, J. R. Jaeger Jan 2018

Can Modified Intensive Early Stocking Be Used In Cow/Calf Production?, K. R. Harmoney, J. R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Intensive early stocking (IES) was introduced nearly a half century ago in eastern Kansas and has since been adopted as a major management tool to increase animal production, efficiency of production, and economic return on tallgrass rangelands. These increases have come almost exclusively by using IES with young stocker animals. Intensive early stocking and its gains have been proven effective repeatedly in published research. A similar modified IES (MIES) system has increased production efficiency of stocker animals on western Kansas rangelands. Perennial grassland acres for cattle production, as well as cattle numbers, are declining. Using management practices that mimic a ...


Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer Jan 2018

Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Distillers grains, a by-product of the ethanol industry, have tremendous potential as an economical and nutritious supplement for grazing cattle. Distillers grains contain a high concentration of protein (25 to 30%), with more than two-thirds escaping degradation in the rumen, which makes it an excellent supplement for younger cattle. Recent advancements in the ethanol manufacturing process have resulted in extraction of a greater amount of fat; therefore, creating distillers grains that may contain less energy than corn. This research was conducted to compare performance of stocker cattle supplemented with corn or DDG at 0.5% body weight per head daily ...


Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer, J. K. Farney Jan 2018

Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Tall fescue is the major cool-season grass in southeastern Kansas. Perennial grass crops, as with annual row crops, rely on proper fertilization for optimum production; however, meadows and pastures are often under-fertilized and produce low quantities of low-quality forage. Even when new stands are established, this is often true. The objective of this study was to determine whether N, P, and K fertilization improves yields during the early years of a stand.

Soil Health Profile In Claypan Soils, C. J. Hsiao, G. F. Sassenrath, C. Rice, G. Hettiarachchi, L. Zeglin

Kansas Agricultural Experiment Station Research Reports

Healthy soil is the foundation of a sustainable agronomic production system. Microorganisms include bacteria (such as actinomycetes), fungi, and protozoa. Soil microorganisms, or microbes, exist in large numbers in soils and are critical for decomposition of organic residues and nutrient recycling. Soils with ample and diverse microbial populations can provide more essential nutrients for crop growth and development. Soil microbial properties are considered one of the major indicators of soil health.

Soil microbial properties can be measured by the activity and the composition of micro-organism populations. Phospholipid fatty acids (PLFA) are the primary components of cell membranes, they can be ...
