Anaerobic potentially mineralizable nitrogen (PMN) combined with preplant nitrate test (PPNT) or pre-sidedress nitrate test (PSNT) may improve corn (Zea mays L.) N management. Forty-nine corn N response studies were conducted across the U.S. Midwest to evaluate the capacity of PPNT and PSNT to predict grain yield, N uptake, and economic optimal N rate (EONR) when adjusted by soil sampling depth, soil texture, temperature, PMN, and initial NH4–N from PMN analysis. Pre-plant soil samples were obtained for PPNT (0- to 30-, 30- to 60-, 60- to 90-cm depths) and PMN (0- to 30-cm depth) before corn planting and N fertilization. …

Impact Of Covid-19 On Arkansas Field Crop Farms, A. Durand-Murat, S. Stiles, B. Watkins, C. R. Stark Jr.
AAES Research Reports and Research Bulletins
The coronavirus (COVID-19) pandemic is disrupting the global economy in unprecedented ways, and the agricultural sector is no exception. Prices of most commodities decreased since the pandemic began, which are affecting farm revenues and production costs. We assess the impact of COVID-19 on Arkansas field crop farms using the Representative Farm models, calibrated to the latest baseline published by the Food and Agricultural Policy Research Institute. The results show that COVID-19 decreases the net cash farm incomes of all five farms, increases the probability of having a negative net cash farm income, and increases the cost of commodity programs. Payments …
Genetic Architecture Of Salt And Drought Tolerance In Cowpea, Waltram Second Ravelombola
Genetic Architecture Of Salt And Drought Tolerance In Cowpea, Waltram Second Ravelombola
Graduate Theses and Dissertations
Cowpea [Vigna unguiculata (L.) Walp.] is a diploid and nutrient-dense legume species. It provides affordable source of protein to human. Cowpea cultivation is prevalent in Africa, Asia, the western and southern U.S., and Central and South America. However, earlier reports have shown that drought and salt stress can be devastating to cowpea production. The objectives of this study were to screen for salt and drought tolerance in cowpea and to identify molecular markers associated with these traits. Simple methodologies to screen for drought (Chapter 2) and salt tolerance were developed (Chapter 3). Results suggested that: 1) a total of 14, …
Recombinase-Mediated Integration Of A Multigene Cassette In Rice Leads To Stable Expression And Inheritance Of The Stacked Locus, Bhuvan Pathak, Vibha Srivastava
Recombinase-Mediated Integration Of A Multigene Cassette In Rice Leads To Stable Expression And Inheritance Of The Stacked Locus, Bhuvan Pathak, Vibha Srivastava
Crop, Soil and Environmental Sciences Faculty Publications and Presentations
Efficient methods for multigene transformation are important for developing novel crop varieties. Methods based on random integrations of multiple genes have been successfully used for metabolic engineering in plants. However, efficiency of co-integration and co-expression of the genes could present a bottleneck. Recombinase-mediated integration into the engineered target sites is arguably a more efficient method of targeted integration that leads to the generation of stable transgenic lines at a high rate. This method has the potential to streamline multigene transformation for metabolic engineering and trait stacking in plants. Therefore, empirical testing of transgene(s) stability from the multigene site-specific integration locus …

Photosynthetic Activity And Yield Of Pegaga (Hydrocotyle Bonariensis) Grown Under Natural And Artificial Light, Narayanan Indiran Nair
Student Works (2020-2029)
Large leaf pennywort (Hydrocotyle bonariensis) also known as Pegaga in Malaysia, is an herb belonging to the family Araliaceae and commonly used as a culinary leafy vegetable and in preparation of traditional medicines to treat various symptoms of ophthalmic diseases and eczema. The plant is also used as an emetic, diuretic and laxative. With the increasing demand for H. bonariensis by the herbal industry, sourcing plant materials from natural habitats is no longer an economically viable or environmentally sustainable proposition. H. bonariensis is highly sensitive to direct sunlight exposure and water scarcity, which makes successful farming dependent on weather conditions …
Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou
Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou
International Programs
A soil assessment was carried out in the savannah region of Togo in 2018, aiming at drawing the digital map of Togo’s soil fertility and making fertilizer recommendations. Soil samples were taken from geo-referenced GPS points and were analyzed for parameters such as water pH, Organic matter, available phosphorus and exchangeable potassium. Thematic maps have been drawn using an ArcGIS package. The results showed that the soils of the Savannah region in Togo are mainly (84%) not very acidic (pH = 5.5 to 6.5), overall poor to very poor (84%) in organic matter (<2% OM), essentially poor to very poor (86%) in available phosphorus (<15 mg/kg of soil) and mostly very poor (87%) in exchangeable potassium (<90 mg / kg of soil). These results allowed the agricultural research institute of Togo to make fertilizer use recommendations and to develop, in partnership with Morocco, a digital platform (fertitogo.tg ) for decision making in crop fertilization.
Sensitivity Of Enlisttm And Roundup Ready Xtend® Technologies To Auxin Herbicides And Comparison Of Resistance To Susceptible Cotton And Soybean Cultivars, James Rose
Graduate Theses and Dissertations
Increases in weed resistance have led to the development of new herbicide-resistant crop technologies, namely the Roundup Ready Xtend® and EnlistTM weed control systems. These new technologies provide resistance to applications of the synthetic auxins dicamba or 2,4-D, respectively, in traited cotton or soybean. It is unknown if there is any resistance to other herbicides within the synthetic auxin group (WSSA Group 4) in these traited crops. Experiments were conducted with auxin herbicides representing all five families within WSSA Group 4. Herbicides were applied either preemergence (PRE) or postemergence (POST) relative to the crop in a single application. Applications were …
Evaluating Opportunities For Integrated Crop Livestock Systems In Eastern Nebraska, Elizabeth Kay Christenson
Evaluating Opportunities For Integrated Crop Livestock Systems In Eastern Nebraska, Elizabeth Kay Christenson
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Current agricultural systems focused on production of few commodities are facing production, economic, and environmental challenges. To address these challenges, Integrated Crop Livestock Systems (ICLS) have emerged through three primary methods 1) perennial grasslands for grazing and/or hay production, 2) crop residue grazing, and 3) cover crop grazing. To evaluate potential of ICLS mitigating current challenges, a field scale model ICLS was developed in 2015. The ICLS includes 4-ha each of ‘Newell’ smooth bromegrass (Bromus inermis L.), ‘Liberty’ switchgrass (Panicum virgatum L.), and ‘Shawnee’ switchgrass. The ICLS also included 8-ha of continuous corn (Zea mays L.). In …
Performance Evaluation Of Four Arkansas Table Grape Cultivars Grown On Three Trellis Systems Under High Tunnels At Two Locations In Arkansas., Jose Hernandez
Performance Evaluation Of Four Arkansas Table Grape Cultivars Grown On Three Trellis Systems Under High Tunnels At Two Locations In Arkansas., Jose Hernandez
Graduate Theses and Dissertations
Grapevines (Vitis vinifera L.) are one of the most important horticultural crops world-wide. In the southern U.S. region, hot and humid climate accompanied by high pest pressure requires high levels of labor and pesticide inputs, making open field table grape production unsustainable. Previous research at University of Arkansas has demonstrated that table grape production under high tunnels (HTs) is a viable option to overcome biotic and abiotic challenges in the region. This project evaluated two HTs established in Arkansas. In the spring of 2014, at Fayetteville, three table grape cultivars (Faith, Gratitude, and Jupiter) were established in an 8 x …

Phenotypic And Genotypic Studies In The Peach [Prunus Persica (L.) Batsch] And Muscadine Grape (Vitis Rotundifolia Michx.), Jennifer Anne Lewter
Graduate Theses and Dissertations
Peach: Peaches [Prunus persica (L.) Batsch] are routinely chilled to increase shelf-life. Exposure to temperatures of 5° C for two weeks can induce chilling injury (CI) symptoms, including flesh mealiness (or wooliness) and a lack of juiciness. Phenotypic data were collected on seven biparental F1 peach populations maintained at the University of Arkansas Fruit Research Station. A genome wide association study (GWAS) was performed using TASSEL 5 which identified four quantitative trait loci (QTLs) associated with expressible juice, four QTLs for mealiness, five QTLs for soluble solids, and three QTLs for fruit weight. Exploiting these genetic markers could help breeders …
