Creating Awareness Of The Turkey Industry Through Stem-Based Online Curriculum, Elizabeth Simmermeyer, Elizabeth Karcher
Indiana STEM Education Conference
As the food industry has evolved over the years, consumers have more accessible and convenient outlets to buy groceries, dine in, or carry out. While there are many advantages to this ever-changing industry, a large gap exists in the understanding of food production from farm to fork. Consumer perceptions are influenced beginning at an early age. Education is the solution to bridge this gap between farm to fork; however, there are limited STEM-based agricultural resources available for teachers to implement in their classrooms. Creating these agricultural resources provides teachers the opportunity to share the story of the agricultural industry with …

Effects Of Using Low Tunnel And Grafted Plants For Watermelon Production Under Low Temperature Stress In Indiana, Wenjing Guan
Midwest Vegetable Trial Reports
This study evaluated the effect of using low tunnel and grafted plants for early-season watermelon production in Indiana. Results of the study indicated that grafted seedless watermelon plants can better tolerate cold stress in the early watermelon season compared to non-grafted seedless watermelon plants. Grafted plants with ‘Camelforce’ rootstock had better old tolerance than that of ‘Carolina Strong Back’ rootstock. The effect of using low tunnels to improve plant survival rate under extreme weather conditions is limited, which depend on temperate stress and cold tolerance of the plants.

Peanut smut caused by Thecaphora frezii is a severe fungal disease currently endemic to Argentina and Brazil. The identification of smut resistant germplasm is crucial in view of the potential risk of a global spread. In a recent study, we reported new sources of smut resistance and demonstrated its introgression into elite peanut cultivars. Here, we revisited one of these sources (line I0322) to verify its presence in the U.S. peanut germplasm collection and to identify single nucleotide polymorphisms (SNPs) potentially associated with resistance. Five accessions of Arachis hypogaea subsp. fastigiata from the U.S. peanut collection, along with the resistant …

Unmanned aerial vehicles (UAV) carrying multispectral cameras are increasingly being used for high-throughput phenotyping (HTP) of above-ground traits of crops to study genetic diversity, resource use efficiency and responses to abiotic or biotic stresses. There is significant unexplored potential for repeated data collection through a field season to reveal information on the rates of growth and provide predictions of the final yield. Generating such information early in the season would create opportunities for more efficient in-depth phenotyping and germplasm selection. This study tested the use of high-resolution time-series imagery (5 or 10 sampling dates) to understand the relationships between growth …

Harvest Of The Month, Abigail E. Heidenreich
Indiana STEM Education Conference
Harvest of the Month curriculum exists in many states, but Indiana lacks a statewide effort in this area. To meet this need, collection of lessons with complementary activities that are specific to Indiana agriculture were created. The driving force behind the curriculum was to create a lesson that is fun and engaging for students, but also well-rounded and standards-based for teachers. Components of the lesson include Life Cycle Discussions, Taste Testing, Interactive Activities, and Journal Prompts. Partnering with Indiana farmers, a harvest video was created to accompany each lesson that features a different agricultural product grown in Indiana each month. …

Veganic Agriculture In The United States: Opportunities For Research, Outreach, And Education, Alisha Utter, Mona Seymour
Urban and Environmental Studies Faculty Works
A growing number of farmers are excluding animal inputs from crop production, an approach commonly referred to as veganic or stockfree organic agriculture. This research-based article discusses the soil health and fertility strategies reported by a sample of U.S. veganic farmers. These approaches may be relevant beyond the veganic community to farmers seeking innovative methods for produce safety and nutrient cycling. Agricultural outreach professionals (AOPs), including Extension personnel, play a critical role in supporting veganic practices by serving as cross-pollinators between farmers and research institutions. Thus, the article endeavors to expand AOP familiarity with veganic practices and benefits.

Plant Species Identification In The Wild Based On Images Of Organs, Meghana Kovur
Graduate Theses, Dissertations, and Problem Reports (ETD)
Image-based plant species identification in the wild is a difficult problem for several reasons. First, the input data is subject to a very high degree of variability because it is captured under fully unconstrained conditions. The same plant species may look very different in different images, while different species can often appear very similar, challenging even the recognition skills of human experts in the field. The large intra-class and small inter-class image variability makes this a fine-grained visual classification problem. One way to cope with this variability and to reduce image background noise is to predict species based on the …

Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …

Department of Political Science: Faculty Publications
The flash drought and its associated heat wave that affected western Russia in the summer of 2010 had significant cascading agricultural and socioeconomic impacts. Drought indicators sensitive to soil moisture and evapotranspiration (ET) showed that the flash drought began in June 2010, then intensified rapidly and expanded to cover much of western Russia. By early July, almost all of the major wheat producing regions of Russia were experiencing extreme water stress to the winter and spring wheat crops. The timing of the onset of the flash drought was particularly devastating as the period of most rapid intensification overlapped with the …

Abrasive Weeding As A Vehicle For Precision Fertilizer Management In Organic Vegetable Production, Tran Kim Ngan Luong, Frank Forcella, Sharon Clay, Michael S. Douglass, Samuel E. Wortman
Department of Agronomy and Horticulture: Faculty Publications
Abrasive weeding is a nonchemical weed control tactic that uses small, gritty materials propelled with compressed air to destroy weed seedlings. Organic fertilizers have been used successfully as abrasive grits to control weeds, but the goal for this study was to explore the effects of fertilizer grit, application rates, and background soil fertility on weeds, plant available nitrogen (N) uptake, and crop yield. Field trials were conducted in organic ‘Carmen’ sweet red pepper (Capsicum annuum) and organic ‘Gypsy’ broccoli (Brassica oleracea var. italica) and treatments included organic fertilizer grit (8N–0.9P–3.3K vs. 3N–3.1P–3.3K), grit application rates (low …

Modern plant breeding increasingly relies on genomic information to guide crop im- provement. Although some genes are characterized, additional tools are needed to effectively identify and characterize genes associated with crop traits. To address this need, the mPing element from rice was modified to serve as an activation tag to in- duce expression of nearby genes. Embedding promoter sequences in mPing resulted in a decrease in overall transposition rate; however, this effect was negated by using a hyperactive version of mPing called mmPing20. Transgenic soybean events carrying mPing-based activation tags and the appropriate transposase expression cassettes showed evidence of transposition. …

The Role Of Peer Irrigators On The Choice And Intensity Of Use Of Irrigation Techniques, Noah Hayward, Kent Kovacs
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The use and the proportion of farmland that uses prominent irrigation practices in Arkansas were evaluated. A bivariate sample selection model evaluated the determinants of the share of irrigated land in a farm that uses each practice. In addition, the relationship between the irrigation practices a peer uses and the use and intensity of five common irrigation practices was evaluated. If a peer of an Arkansas farmer used center pivot irrigation, this increased the probability that the farmer used center pivot irrigation by 66 percentage points. A peer that used pivot irrigation decreased the proportion of irrigated land that used …
