Food System And Water–Energy–Biodiversity Nexus In Nepal: A Review, Roshan Subedi, Madhav Karki, Dinesh Panday Aug 2020

Food System And Water–Energy–Biodiversity Nexus In Nepal: A Review, Roshan Subedi, Madhav Karki, Dinesh Panday

Department of Agronomy and Horticulture: Faculty Publications

Water, energy, and biodiversity are essential components for building a sustainable food system in a developing country like Nepal. Green Revolution technologies and the package of practices largely ignored the role of ecosystem services, leaving a large population of small farmers’ food- and nutrition-insecure. Biodiversity, especially, agrobiodiversity is in decline and this vital cross-cutting element is less discussed and interlinked in nexus literature. The interlinking food system with water–energy–biodiversity nexus, therefore, is essential to achieve a resilient food system. It ensures the vital structures and functions of the ecosystem on which it is dependent are well protected in the face …

Effects Of Char On Nitrogen Management In Agricultural Soils Of Semi-Arid Western Nebraska, Dinesh Panday Aug 2020

Effects Of Char On Nitrogen Management In Agricultural Soils Of Semi-Arid Western Nebraska, Dinesh Panday

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Soils in western Nebraska are characterized by low soil organic C due to semi-arid environment in the region and further aggravated by disruption of soil aggregates and rapid C decomposition from intensive tillage, erosion, and frequent droughts. Proper management of soil C may improve soil properties, reduce N losses, and subsequently improve crop yields in this low C soil and low moisture condition. This dissertation focuses on C-rich coal char (henceforth “char”) as a potential strategy to overcome the existing problem of low C in semi-arid region. Char is an industrial by-product, resulting from inefficient coal burning during sugar beet …


Fate And Transport Of Phosphorus-Containing Land-Applied Swine Slurry In A Karst Watershed, A. N. Sharpley, M. B. Daniels, K. R. Brye, K. Vandevender, J. Burke, L G. Berry, P. Webb Aug 2020

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Phosphorus distribution in pasture soils underlain with karst geology was determined on a 0.10-ha grid in 2014, 2016, and 2018. Two fields (Fields 1 and 12) received swine slurry from a concentrated animal feeding operation, whereas another (Field 5) received mineral fertilizer. All fields were grazed by cattle and periodically hayed. Mean Mehlich-3 extractable P in the top 10 cm increased (p ≤ .05 level) for Fields 1 (59–91 mg kg−1) and 12 (63–122 mg kg−1) between 2014 and 2018, with little change for Field 5 (45–47 mg kg−1). Over the 5-yr monitoring …


Soil Moisture, Temperature, And Oxidation-Reduction Potential Fluctuations Across A Furrow-Irrigated Rice Field On A Silt-Loam Soil, Diego Della Lunga, Kristofor R. Brye, Jordan M. Slayden, Christopher G. Henry, Lisa S. Wood Aug 2020

Soil Moisture, Temperature, And Oxidation-Reduction Potential Fluctuations Across A Furrow-Irrigated Rice Field On A Silt-Loam Soil, Diego Della Lunga, Kristofor R. Brye, Jordan M. Slayden, Christopher G. Henry, Lisa S. Wood

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Alternative water management practices for rice (Oryza sativa) production have been developed for water conservation purposes, such as the furrow-irrigated rice production system, which results in variable volumetric water content (VWC), temperature, and oxidation-reduction (redox) potential conditions. The spatial and temporal variations in environmental factors can affect greenhouse gas (GHG) emissions. The objective of this field study was to document and evaluate the continuous variations in soil water content, temperature, and redox potential over two growing seasons (2018 and 2019) among site positions (up-, mid-, and down-slope) and tillage treatments [conventional tillage (CT) and no-tillage (NT)] under furrow-irrigated …


Water Management Effects On Trace Gas Emissions Under Greenhouse Conditions From Direct-Seeded Hybrid Rice In A Silt-Loam Soil, Diego Della Lunga, Kristofor R. Brye, Trenton L. Roberts, Shelby G. Lebeau Aug 2020

Water Management Effects On Trace Gas Emissions Under Greenhouse Conditions From Direct-Seeded Hybrid Rice In A Silt-Loam Soil, Diego Della Lunga, Kristofor R. Brye, Trenton L. Roberts, Shelby G. Lebeau

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Water management regimes influence greenhouse gas emissions in rice (Oryza sativa L.) production. The objective of this study was to quantify methane (CH4 ), nitrous oxide (N2 O), and carbon dioxide (CO2 ) under direct-seeded conditions in the greenhouse to evaluate the effects of water regime on fluxes and growing-season-long emissions. Research was conducted during 2019 using a hybrid rice cultivar (RT 7311 CL) grown in a DeWitt silt loam (Albaqualf). Six plastic tubs, filled with 21 kg of soil and manually seeded, were arranged in a completely random design with two replications of three water regime treatments: i) flooded, …

Grain and Other Field Crops Research Articles

We present the first genetic map of tedera (Bituminaria bituminosa (L.) C.H. Stirton), a drought-tolerant forage legume from the Canary Islands with useful pharmaceutical properties. It is also the first genetic map for any species in the tribe Psoraleeae (Fabaceae). The map comprises 2042 genotyping-by-sequencing (GBS) markers distributed across 10 linkage groups, consistent with the haploid chromosome count for this species (n = 10). Sequence tags from the markers were used to find homologous matches in the genome sequences of the closely related species in the Phaseoleae tribe: soybean, common bean, and cowpea. No tedera linkage groups align in their …


Influence Of Cover Crop Management Practices On Rainfed Corn Production In Semi-Arid Western Nebraska, Alexandre Tonon Rosa Jul 2020

Influence Of Cover Crop Management Practices On Rainfed Corn Production In Semi-Arid Western Nebraska, Alexandre Tonon Rosa

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

With the increased cover crop (CC) popularity, producers of semi-arid regions of western Nebraska are questioning whether they could successfully incorporate CC into their rainfed winter wheat (Triticum aestivum L.)-corn (Zea mays L.)-fallow rotations. The major concern is that CCs may deplete soil water affecting the subsequent crop. Therefore, three studies were established under rainfed conditions of western Nebraska to access the effects of CCs on soil water, soil compaction, nutrient cycling, weed demographics, residue coverage, and subsequent corn yield. The first study evaluated the influence of CC planting and termination times prior to corn establishment. Late termination …
