To improve the economic and environmental sustainability of agriculture, information is needed on how to target research, teaching, and outreach programs. However, conducting survey research in general, and with agricultural producers specifically, is increasingly challenging given issues such as declining response rates and limited resources. While studies examining the best practices for promoting higher response rates exist, few focus explicitly on agricultural producers. In three separate surveys conducted with agricultural producers in South Dakota in 2018 and 2019, we included experiments testing how token pre-incentives, a research partnership, and response mode options impacted response rates. We also examined how sample …

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas
Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas
Bulletins 4000 -
In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

Amelioration of K deficiency during the growing season requires knowledge of critical tissue concentrations and crop yield response to fertilization time. Our objectives were to characterize the yield and uptake responses of K-deficient irrigated soybean [Glycine max (L.) Merr.] to in-season fertilizer-K application time and rate, evaluate fertilizer-potassium-recovery efficiency (FKRE), and evaluate how leaflet-K concentration responds to K-fertilization time. Six trials were established on silt loam soils. Muriate of potash was applied pre-plant and compared to an equivalent K rate applied post-emergence on six or seven dates. Grain yield, trifoliolate-K concentration, and K uptake were measured. Relative soybean yields …

Soybean injury following an application of metribuzin soon after planting can occur under cool, wet conditions, especially for varieties that lack a high level of tolerance to the herbicide. Field experiments were conducted in 2017 and 2018 in Fayetteville, AR, to evaluate the impacts of metribuzin at 0, 280, 560, 840, and 1,120 g ai ha−1 on soybean growth and incidence of soil-borne fungi. Three classes of metribuzin tolerance (sensitive, moderately tolerant, and tolerant) were evaluated based on a previous screen. In both years, visible injury to soybean was impacted by varietal tolerance and metribuzin rate. As metribuzin rate …

Recycling P from wastewaters may provide a sustainable source of P that could also protect surface water quality from P enrichment. Struvite (MgNH4PO4·6H2O) is a material that can be created from P-containing wastewater and has been shown to have agricultural fertilizer value. The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (Crystal Green, CG), diammonium phosphate (DAP), monoammonium phosphate (MAP), rock phosphate (RP), and triple superphosphate (TSP) on corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] response in a 79-d greenhouse …
Effects Of Char On Nitrogen Management In Agricultural Soils Of Semi-Arid Western Nebraska, Dinesh Panday
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 …

Profit-Maximizing Potassium Fertilizer Recommendations For Soybean, Michael P. Popp, Nathan A. Slaton, Trenton L. Roberts
Crop, Soil and Environmental Sciences Faculty Publications and Presentations
Potassium (K) fertilizer has important yield and cost ramifications in soybean [Glycine max (L.) Merr.] production. Rate recommendations are often based on expected yield response as predicted by a soil test. To that end, soybean response to K application rate studies were analyzed using 86 site-years from 2004 to 2019. We estimated a generic yield response curve across soybean cultivar and soil texture to allow calculation of profit-maximizing K rates for producers in the mid-southern United States that also consider crop value and fertilizer cost. Further, we compared profit-maximizing fertilizer-K rates with those currently recommended. Using a spreadsheet-based decision …

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 …

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, …

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 …

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
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 …
