Soybean Maturity Group And Planting Date Influence Grain Yield And Nitrogen Dynamics, Carrie C. Ortel, Trenton L. Roberts, Kyle A. Hoegenauer, Larry C. Purcell, Nathan A. Slaton, Edward E. Gbur
Soybean Maturity Group And Planting Date Influence Grain Yield And Nitrogen Dynamics, Carrie C. Ortel, Trenton L. Roberts, Kyle A. Hoegenauer, Larry C. Purcell, Nathan A. Slaton, Edward E. Gbur
Crop, Soil and Environmental Sciences Faculty Publications and Presentations
Manipulation of soybean [Glycine max (L.) Merr.] maturity group (MG) and planting date will increase the yield of a soybean crop while simultaneously influencing the potential soil-nitrogen (N) credits. Variations in N returned to the soil by soybean can significantly affect the amount of fertilizer-N needed for the subsequent crop. Four soybean MGs (3.5, 4.7, 5.4, and 5.6) were evaluated at optimal and late planting dates in Arkansas. Grain yield was significantly different among MGs in 2016 (P = .0012) and 2017 (P = .0004), with the 4.7 MG consistently yielding the highest at 3,232 kg ha(-1). Plant total aboveground …

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 …
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, …
Photosynthetic Activity And Yield Of Pegaga (Hydrocotyle Bonariensis) Grown Under Natural And Artificial Light, Narayanan Indiran Nair
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 …

Projected Surface Water For Fruit And Vegetable Irrigation Under A Changing Climate In The Us, Marty Matlock, Greg Thoma, Kieu Ngoc Le, Eric Cummings, Zach Morgan, Andrew Shaw
Water Systems
Increasing greenhouse gas concentrations in the atmosphere, resulting in climate impacts, are raising concerns over the hydrologic cycle and its effects upon agricultural productivity. If rainfall patterns change, meeting an increased demand for fruits and vegetables will pose a challenge for domestic production regions in the United States (U.S.). Information on potential water supply scarcity in the current production regions provides decision makers with critical information for risk mitigation for future production. We used a hydrologic balance-based model of historic and future water availability to evaluate risk of available irrigation water to support major fruit and vegetable production the US. …
