Characterizing The Decision Process In Setting Corn And Soybean Seeding Rates, David A. Hennessy, Alexander J. Lindsey, Yuyuan Che, Laura E. Lindsey, Maninder Pal Singh, Hongli Feng, Elizabeth M. Hawkins, Sakthi Subburayalu, Roy Black, Eric A. Richer, Daniel S. Ochs 2022 Michigan State University

Characterizing The Decision Process In Setting Corn And Soybean Seeding Rates, David A. Hennessy, Alexander J. Lindsey, Yuyuan Che, Laura E. Lindsey, Maninder Pal Singh, Hongli Feng, Elizabeth M. Hawkins, Sakthi Subburayalu, Roy Black, Eric A. Richer, Daniel S. Ochs

The Journal of Extension

Selecting optimal corn and soybean seeding rates are difficult decisions to make. A survey of Ohio and Michigan farm operators finds that, although generally keen to learn from others, they tend to emphasize their own experience over outside information sources. Soybean growers declare university and extension recommendations as more important than do corn growers. In response to direct queries and in free comments, growers place more emphasis on understanding the agronomic and technological problems at hand than on adjusting to the market environment. Given the decision environment, we argue that these responses are reasonable.


Cultural Sensitivity: A Requirement When Developing Food Safety Interventions, Lillian Nabwiire, Angela M. Shaw, Gail R. Nonnecke, David D. Minner, Ellen Johnsen, Louis E. Petersen Jr 2022 Iowa State University

Cultural Sensitivity: A Requirement When Developing Food Safety Interventions, Lillian Nabwiire, Angela M. Shaw, Gail R. Nonnecke, David D. Minner, Ellen Johnsen, Louis E. Petersen Jr

The Journal of Extension

Extension materials that are sensitive to changing demographics and culture increase relevance and compliance with food safety practices. Produce safety extension materials were developed for U.S. Virgin Islands (USVI) produce growers to help with compliance with a new food safety rule. We developed employee training materials based on a needs assessment and behavioral change was evaluated six months after dissemination. The original materials were not seen as culturally appropriate but after modifications, improvements in food safety practices and behavior changes were observed. These results suggest that extension educators should seek feedback from target populations about potential interventions before implementation.


Influence Of Core Temperature On Psychomotor Performance During Cold Weather Military Training, Douglas Jones, Rebecca Weller, Stephen Eggan, Nicholas Roberts, Weimin Zheng, Jay Heaney, Timothy Dunn 2022 Naval Health Research Center

Influence Of Core Temperature On Psychomotor Performance During Cold Weather Military Training, Douglas Jones, Rebecca Weller, Stephen Eggan, Nicholas Roberts, Weimin Zheng, Jay Heaney, Timothy Dunn

Journal of Human Performance in Extreme Environments

Purpose: Cold environments may deteriorate psychomotor performance due to slowing of neuronal signals, distractions caused by pain and discomfort, and a loss of manual dexterity. The extent to which core temperature (Tc) influences psychomotor performance in the cold has not been established. Therefore, psychomotor performance and Tc were assessed during a cold weather military training exercise to evaluate this relationship.

Methods: Thirty-six military personnel (age: 26 ± 4 yr, ht: 175 ± 8 cm, wt: 79.1 ± 11.1 kg) participating in cold weather training volunteered for this study. Participants completed a 10-min immersion in cold (1°C) water, followed ...


Iam Hiq—A Novel Pair Of Accuracy Indices For Imputed Genotypes, Albert Rosenberger, Viola Tozzi, Heike Bickeböller, Susanne M. Arnold, The INTEGRAL-ILCCO Consortium 2022 Georg-August-University Göttingen, Germany

Iam Hiq—A Novel Pair Of Accuracy Indices For Imputed Genotypes, Albert Rosenberger, Viola Tozzi, Heike Bickeböller, Susanne M. Arnold, The Integral-Ilcco Consortium

Markey Cancer Center Faculty Publications

Background: Imputation of untyped markers is a standard tool in genome-wide association studies to close the gap between directly genotyped and other known DNA variants. However, high accuracy with which genotypes are imputed is fundamental. Several accuracy measures have been proposed and some are implemented in imputation software, unfortunately diversely across platforms. In the present paper, we introduce Iam hiQ, an independent pair of accuracy measures that can be applied to dosage files, the output of all imputation software. Iam (imputation accuracy measure) quantifies the average amount of individual-specific versus population-specific genotype information in a linear manner. hiQ (heterogeneity in ...

Farmers’ Perceptions On Different Forage Types In Southern Highlands Of Tanzania, B. Nzogela, S. W. Mwendia, A. J. Mwilawa, J. Kizima, J. Bwire, A. O. Notenbaert

International Grassland Congress Proceedings

Feed and forages take the bulk of inputs required in livestock production. Inadequate forages in quality and quantity in sub-Saharan Africa is responsible for low livestock productivity. Addressing livestock feed requirements presents quick wins in livestock productivity compared to breeding and health. In a Climate Smart Dairy project implemented in Tanzania, we demontrated several forage options to farmers including, two cultivars of Pennisetum purpureum, two Urochloa hybrids, Chrloris gayana and Tripsacum andersonii (control). Where applicable, the grasses were intercropped with either one of the following forage legume, Desmodium intortum, Lablab purpureus or Stylosanthes guiyanensis. Fourteen forage treaments were obtained in ...

Examining The Impact Of Patch Burning On Livestock Grazing Patterns In Edwards Plateau, Texas, W. G. Gao, J. P. A. Angerer, X. B. W. Wu, D. T. Tolleson

International Grassland Congress Proceedings

Production of sheep, goat, and cattle are major agricultural enterprises on West Texas rangelands, especially in the Edwards Plateau. In this region, the use of fire as a management tool was suppressed until recently. Although previous studies have been conducted to evaluate cattle use of burned versus unburned patches, there has been a lack of studies where combinations of livestock species grazing together on patch burned areas have been evaluated. The objective of this study is to examine grazing patterns of cattle, sheep and goats, both spatially and temporally, on areas where patch burning has been implemented. The study site ...

Effects Of Maturity And Drying Method On The Nutritive Value Of Tropical Grasses In Nicaragua, Rocky Lemus, R. Van Der Hoek, Y. C. Newman, M. Mena, K. A. Albrecht

International Grassland Congress Proceedings

Tropical grasses are key components for both grazing and conserved forages in sustainable livestock systems (beef and dairy) in Central America. The objective of the study was to evaluate grasses used in Nicaragua and their nutritive value contribution as preserved forage during the dry season under different drying methods. Five tropical bunch grasses (Andropogon gayanus, Hyparrheniarufa, Urochloabrizantha, Megathyrsus maximus, and Cenchruspurpureus) were sampled across different farms in Nicaragua in 2014 and 2015 using three replications. Forage samples were collected at 2, 4, 6, and 8-wk maturity as well as season long samples. Samples drying methods included sun- and oven-dried. Sun-dried ...


Effects Of Harvest Frequency On Yield And Self-Thinning In Irrigated Orchardgrass (Dactylis Glomerata L.) In Oregon, Usa, G. Jones 2022 Oregon State University

Effects Of Harvest Frequency On Yield And Self-Thinning In Irrigated Orchardgrass (Dactylis Glomerata L.) In Oregon, Usa, G. Jones

International Grassland Congress Proceedings

Persistence is an important factor in the economic management of perennial grass swards. Frequent harvest is occasionally attributed to poor stand persistence, but self-thinning theory indicates that infrequent harvest should cause swards to thin as tillers compete for light. This experiment aimed to demonstrate and qualify self-thinning in orchardgrass managed under differing harvest frequencies. Orchardgrass was planted in September 2018 and then clipped, fertilized and divided into experimental units in March 2019. Plots were randomly assigned one of four harvest frequency treatments (n = 5): No harvest, one harvest, two harvests, and four harvests. Irrigation water and fertilizer were applied to ...

International Grassland Congress Proceedings

Managing ecological systems sustainably requires a deep understanding of ecosystem structure and the processes driving their dynamics. Conceptual models can lead to improved management, by providing a framework for organizing knowledge about a system and identifying the causal agents of change. We developed state-and-transition models (STMs) to describe landscape changes in Iceland over three historical periods with different human influence, from pre-settlement to present days. Our models identified the set of possible states, transitions and thresholds in these ecosystems and their changes over time. To illustrate the use of these models for predicting and improving management interventions, we applied our ...

International Grassland Congress Proceedings

Magallanes region, located southern Chile, contains about 1.9 million sheep heads, in about 5 million hectares of rangelands. However, forage production is concentrated in small wetlands meadows called locally “Vegas” that only represent about 300.000 hectares. Those ecosystems that sustain patagonian ranches, produce 20 times more forage biomass than the surrounding natural rangelands. Patagonian vegas have concave topography with a hydrophyte (wet) center, and mesic slopes and xeric highlands of Festuca gracillima. Although the moisture content is controled by topography, there is scarce information about the movement of water through this concave topography. Also, the spatial variability of ...

“Rangelands in most parts of the world are relatively homogenous and can be managed uniformly at the landscape scale” or “rangelands are extremely diverse and require different approaches even at the landscape scale.” Both statements are made frequently by rangelands scientists and managers. Both are correct. Whether or not it is worthwhile to consider soil variability when planning management and restoration at the landscape scale depends on objectives, location, and the management or restoration strategies under consideration. Together these factors determine whether outcomes are likely to be different at different locations in the landscape, and whether those outcomes can be ...
