Magical Wheat, Kjeisten Secretan

USU Student Folklore Fieldwork

In a cave up American Fork canyon, my neighbor found some vases full of wheat which had been there for a long time and they sent them to General Mills and they said it can fight diseases naturally, this wheat, and they asked if they could do some more tests on it and stuff, he told them they could, but he grew some every year and his friend grew some every year so they would have some. They would give them out to the scout kids when they would tell this story. They told us to chew it up.

The Economic Benefits Of The South African Agricultural Research Council’S Wheat Breeding Program: 1992–2015, Matthew James Coale

Graduate Theses and Dissertations

Although classified as an upper middle-income country by the World Bank, food insecurity is still a concern throughout South Africa, as was evident in 2014–2015 when a drought left 22% of households food insecure. As such, agricultural research in South Africa is needed specifically in plant breeding to increase yields and help mitigate future food insecurity. To fill this need, the South African government funds the Agricultural Research Council (ARC), which conducts holistic research on wheat and other crops. Wheat is important to South African food security; due to the significant drop in wheat area planted since the abolishment of …

Behavior Of Copper Oxide Nanoparticles In Soil Pore Waters As Influenced By Soil Characteristics, Bacteria, And Wheat Roots, Joshua Hortin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of this project was to study the behavior of copper oxide nanoparticles in soil environments. Copper oxide nanoparticles have antimicrobial properties and may also be used in agricultural settings to provide a source of copper for plant health, but accidental or misapplication of these nanoparticles to soil may be damaging to the plant and its associated bacteria.

Dissolved soil organic matter that is present in soil pore waters dissolved nanoparticles, but did not dissolve the expected amounts from a geochemical model because the geochemical model did not take into account surface chemistry or coating of the nanoparticles by …

Patent Focus: Growing A Multimillion Dollar Industry For The State Of Kansas, Tiffany Roney

Seek

The years of 2016 and 2017 will go down as bin-busters for Kansas State University plant breeders. K-State normally produces one wheat variety every one or two years, but in 2016 andso far in 2017, K-State breeders have produced six new varieties of wheat. The breedersalso were productive with canola, soybeans and grass, putting out two canola varieties,one soybean variety and the first turfgrass variety in several years. According to K-State plant breeders and licensing experts, these 10 new varieties will generate millions of dollars for the state, the university and Kansas farmers.

Characteristics Of Four Agricultural Crops Established As Northern Bobwhite Brood Habitat, Denise A. Maidens, John P. Carroll

National Quail Symposium Proceedings

Small plots of agricultural crops are often planted in the Southeast for northern bobwhite (Colinus virginianus) management. Often these are viewed as primarily winter habitat, and assumed to provide summer habitat. We evaluated the macroinvertebrate and vegetative structure of millet, sorghum, wheat, and soybean plots on a cotton farm to assess their value as bobwhite brood habitat. During June and July 1999 and June, July, and August 2000, we studied 5 blocks, each planted with all 4 agricultural crops. We measured invertebrate abundance along a 15-meter transect in each plot using vacuum sampling and height/density of vegetation. Visual obstruction readings …

Markets with petroleum products as primary inputs face unique price pressures. I provide a thorough analysis of U.S. wheat prices to investigate connections between international petroleum markets and commodity prices in the US. This research is critical for farmers, policymakers, and scholars interested in the relationship between crude oil inputs and commodity outputs. The research thus offers novel information for a large proportion of US territory under agricultural cultivation. Moreover, this research has implications for agricultural production and policy formulation around the world. The results of the investigation demonstrate support for high short-term volatility in wheat prices based on oil …

Effects Of Phosphorus Availability On Growth And Leaf Nutrient Concentrations In Wheat, Oat, And Cereal Rye, Jerri Lynn Dodson

MSU Graduate Theses

Adequate soil phosphorus (P) is critical for the growth and nutrient content of forages for grazing animals. On low fertility soils, tall fescue responds to P fertilization with increased yields and improved leaf nutrient contents of P, magnesium (Mg), calcium (Ca), and potassium (K) in winter months. My objective was to examine the effect of P availability on growth and leaf nutrients in annual cereal grains commonly grown for winter forage. Soft red winter wheat (Triticum aestivum), oat (Avena sativa), and cereal rye (Secale cereale) were grown hydroponically in greenhouse conditions in complete nutrient solutions with varying P concentrations of …

Genetic Variation In Concentration Of The 33-Mer Protein Subcomponent In Wheat, Robert L. Paris, Kaleb M. Pauley, Ryan K. Lokkesmoe, Sarah E. Lyon, James C. Dunlap, Julia M. Pierre, Timothy Vanwingerden, Finny J. Johns, Kyle J. Kilchrist, Tyler J. Reid, Caleb M. Winn

The Research and Scholarship Symposium (2013-2019)

Celiac Disease is a hypersensitive response to gluten caused by HLA-DQ2 or HLA-DQ8 T-cell presentation, initiating destruction of intestinal epithelial cells. Currently, the only remedy for those suffering from celiac disease is elimination of all gluten from the diet. Studies indicate that an indigestible fragment of the gluten molecule, alpha-gliadin subcomponent 33-mer, rich in proline and glutamine, is responsible for the hypersensitivity response. Determination of 33-mer concentration in wheat lines could be beneficial to future development of wheat lines with reduced 33-mer concentration. Protein from wheat flour was extracted and subjected to ELISA techniques in order to quantify the concentration …

Wheat Streak Mosaic Virus Coat Protein Is A Host-Specific Long-Distance Transport Determinant In Oat, Satyanarayana Tatineni

Department of Plant Pathology: Faculty Publications

Viral determinants involved in systemic infection of hosts by monocot-infecting plant viruses are poorly understood. Wheat streak mosaic virus (WSMV, genus Tritimovirus, family Potyviridae) exclusively infects monocotyledonous crops such as wheat, oat, barley, maize, triticale, and rye. Previously, we reported that WSMV CP amino acids 36–84 are expendable for systemic infection of wheat, maize, barley and rye. In this study, the role of coat protein (CP) in systemic infection of oat by WSMV was examined by using a series of viable deletion mutants. WSMV bearing deletions within or encompassing all of amino acids 36–57 efficiently infected oat, indicating that …

Review Of Nutraceuticals And Functional Properties Of Whole Wheat, Rachana Poudel, Madhav Bhatta

Department of Food Science and Technology: Faculty Publications

Wheat (Triticum aestivum L.) is one of the most commonly cultivated and consumed cereals throughout the world. Though phytochemicals and antioxidants in the cereal grains have not been studied as in fruits and vegetables, given the role of wheat in our diet plate, it is a given of primary importance to understand the chemistry of our major food, wheat. The presence of diverse polyphenols and their action against leading cause of death, including heart diseases, cancer, obesity, and diabetes, widens the scope of wheat. Phytochemicals such as phenolic acids, alkylresorcinols, flavonoids, phytosterols, and carotenoids are present in whole wheat. …

Expression Of The Maize Dof1 Transcription Factor In Wheat And Sorghum, Pamela A. Pena, Truyen Quach, Shirley Sato, Zhengxiang Ge, Natalya Nersesian, Taity Changa, Ismail M. Dweikat, Madhavan Soundararajan, Tom E. Clemente

Department of Agronomy and Horticulture: Faculty Publications

Nitrogen is essential for plant growth and development. Improving the ability of plants to acquire and assimilate nitrogen more efficiently is a key agronomic parameter that will augment sustainability in agriculture. A transcription factor approach was pursued to address improvement of nitrogen use efficiency in two major commodity crops. To this end, the Zea mays Dof1 (ZmDof1) transcription factor was expressed in both wheat (Triticum aestivum) and sorghum (Sorghum bicolor) either constitutively, UBI4 promoter from sugarcane, or in a tissue specific fashion via the maize rbcS1 promoter. The primary transcription activation target of ZmDof1 …

Kansas Agricultural Experiment Station Research Reports

Camelina (Camelina sativaL. Crantz) is a short-seasoned oilseed crop with potential as a fallow replacement crop in dryland wheat (Triticum aestivum) - based cropping systems. Crop rotation management can affect the quality and quantity of crop residue return to the system. In addition, residue has the ability to sequester carbon and can affect plant available water. This study was conducted to investigate the effect of replacing fallow with camelina on crop yield, soil water at wheat planting, soil carbon dioxide (CO₂) efflux from treatments, and residue return. Treatments were four rotation schemes, and included …

Bird Use Of Grain Fields And Implications For Habitat Management At Airports, Raymond B. Iglay, Bruce N. Buckingham, Thomas W. Seamans, James A. Martin, Bradley F. Blackwell, Jerrold L. Belant, Travis L. Devault

USDA Wildlife Services: Staff Publications

Airport properties often include agricultural land cover that can attract wildlife species hazardous to aircraft, despite recommendations against row crops near air operations areas. However, few studies have directly quantified bird use of corn, wheat, and soybean fields relative to bird-aircraft collision (strike) hazard levels to support land cover recommendations. Therefore, we compared bird use among corn, wheat and soybean fields and predicted that corn and wheat would attract bird species recognized as hazardous to aviation. We also anticipated that soybeans would pose minimal attraction to such birds. Here, hazard ranking (low to extremely high) reflects the percentage of strikes …

Wheat, Sheep Or Elvis Presley? Rural Australia Has Had To Change Its Tune, John Connell, Christopher R. Gibson

Faculty of Social Sciences - Papers (Archive)

Rural and regional Australia have had a hard time of late. The economies of Sydney and Melbourne are growing, but much of the rest of their states are not. The population of regional areas is stagnating and agriculture is struggling. Perhaps worst of all there is a feeling that no-one in Canberra or in the booming coastal periphery cares about this. The people of Orange have apparently spoken. Outside Sydney, behind what seems like an impervious sandstone curtain, not all is well. Even the largest towns in regional New South Wales are struggling to retain their populations and have faced …

Large-Scale Dryland Cropping Systems, A. Schlegel, L. Haag

Kansas Agricultural Experiment Station Research Reports

This study was conducted from 2008 to 2016 at the Kansas State University Southwest Research-Extension Center near Tribune, KS. The purpose of the study was to identify whether more intensive cropping systems can enhance and stabilize production in rainfed cropping systems to optimize economic crop production, more efficiently capture and utilize scarce precipitation, and maintain or enhance soil resources and environmental quality. The crop rotations evaluated were continuous grain sorghum (SS), wheat-fallow (WF), wheat-corn-fallow (WCF), wheat-sorghum-fallow (WSF), wheat-corn-sorghum-fallow (WCSF), and wheat-sorghum-corn-fallow (WSCF). All rotations were grown using no-tillage practices except for WF, which was grown using reduced-tillage. The efficiency of …

Seeding Rate For Dryland Wheat, A. Schlegel, J. D. Holman, L. Haag

Kansas Agricultural Experiment Station Research Reports

Four winter wheat varieties (PlainsGold Byrd, Limagrain T158, Syngenta TAM 111, and WestBred Winterhawk) were planted at five seeding rates (30, 45, 60, 75, and 90 lb/a) in the fall of 2014 and 2015 at Colby, Garden City, and Tribune, KS. The objective of the study was to identify appropriate seeding rates for dryland winter wheat in western Kansas. Averaged across varieties, a seeding rate of 60 lb/a seemed to be adequate at all locations in 2015. However, with higher yields in 2016, a higher seeding rate (75 lb/a) was beneficial. The wheat variety T158 was the highest yielding (or …

Characterization Of Pyrenophora Tritici-Repentis In Wheat And Rye To Study Tan Spot Susceptibility And Insights Into Its Relationship With Stem Rust Resistance, Sidrat Abdullah

Electronic Theses and Dissertations

Tan spot, caused by the ascomycete fungus, Pyrenophora tritici-repentis (Ptr), is a major foliar fungal disease of wheat worldwide. To date, Ptr isolates have been grouped into eight races based on the production of three host selective effectors (toxins), Ptr ToxA, ToxB, and ToxC, which are associated with necrosis and chlorosis symptoms on wheat differential lines. In order to see the correlation between stem rust resistance and tan spot susceptibility in 1970’s, to know the pathogen virulence profile, and explore the sources of tan spot resistance, we recovered isolates from wheat and rye and evaluated wheat and rye lines with …

Protein Kinase Activity Toward Taabf1 In Imbibing Grains, Taylor P. Enrico

Honors Theses

The hormones gibberellin and abscisic acid are essential for plant responses to changing environmental conditions, and can send opposing signals. In wheat, the transcription factor TaABF1 plays an important role at the intersection of a gibberellin-induced/abscisic acid-suppressed pathway. When gibberellin dominates, the GA-induced gene, Amy32b, is transcribed. When abscisic acid is dominant, TaABF1 is active and it downregulates GA-induction of Amy32b, while promoting ABA-induced transcription of the gene HVA1. The activity of TaABF1 is thought to be regulated by post-translational phosphorylation at key serine residues. In this study, to determine TaABF1 phosphorylation by wheat kinases, we purified recombinant …

Intensive Management Strategies To Close Wheat Yield Gaps In Central Kansas, B. R. Jaenisch, R. Lollato

Kansas Agricultural Experiment Station Research Reports

Winter wheat is the most widely sown crop in Kansas, and yields had not surpassed 50 bushels per acre until 2015-16, when average state wheat yield was 57 bushels per acre. However, recent estimates of the long-term winter wheat yield potential in central Kansas indicate that it lies around 75 bushels per acre. A particular crop’s yield gap in a given region is determined by the difference between potential and actual yields. The long-term yield gap in Kansas is approximately 45 bushels per acre, which corresponds to more than 50% of the yield potential. Yield gaps have the potential to …

Kansas Agricultural Experiment Station Research Reports

Fusarium head blight (scab) is a common concern in eastern and central Kansas. Wheat seed quality might be compromised following a growing season with severe infestation of scab. Our objectives were to evaluate the effects of variety, seed cleaning method, and seed treatment, on wheat stand establishment and yield following a growing season where scab was severe. A trial was established during the 2015-16 growing season using seed harvested from the 2014-15 growing season, which was characterized by severe infestation of scab. Three commonly grown wheat varieties with differing levels of scab resistance (Everest, SY Wolf, and WB Grainfield) were …

Value Of Fungicide Application In Wheat Production In Southwest Kansas, A. J. Foster, R. Lollato, M. Vandeveer, E. D. De Wolf

Kansas Agricultural Experiment Station Research Reports

During the past several years, applying fungicide to wheat has become a more common practice. The availability of cost-effective generic fungicides, as well as the positive yield responses often reported, seem to be the potential drivers for the adoption of such practices by producers. We conducted a wheat fungicide trial in Garden City, KS, to answer the following questions: 1) Do fungicide applications pay? And 2) Can remote sensing technology be used to quantify the efficacy of different fungicide products? The study consisted of two wheat varieties sown on September 29, 2015 (Oakley CL, highly resistant to stripe rust; and …

Winter Annual Grass Control In Winter Wheat, D. E. Peterson, C. Thompson, C. L. Minihan

Kansas Agricultural Experiment Station Research Reports

Winter annual grasses can be difficult to manage in winter wheat. A field experiment was established near Manhattan, KS, in 2016 to evaluate various preemergence and postemergence herbicide treatments for control of downy brome, cheat, and feral rye. Most treatments were less effective for control of downy brome than cheat. Preemergence and fall postemergence treatments provided better downy brome control than spring postemergence treatments. All herbicide treatments evaluated provided excellent control of cheat, but postemergence treatments were slightly better than preemergence treatments. The only herbicide to control rye was Beyond, which provided better control when applied fall postemergence than spring …

Genotype By Seeding Rate Interaction In Wheat, A. J. Azevedo, S. Varela, R. Lollato, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

Genotype by seeding rate interaction can play a critical role in understanding wheat (Triticum aestivumL.) yield potential. The objective of this study was to quantify wheat yield response to seeding rates by contrasting genotypes (high- vs. low-tillering). One study was planted at two locations: Ashland Bottoms (dryland and conventional tillage) and at Topeka (irrigated and no-tillage) field research stations (Kansas). The two winter wheat varieties were sown at four different seeding rates (40, 80, 120, and 160 lb/a). Measurements consisted of stand counts, canopy coverage (estimated via imagery collection), determination of early-season gaps in the final stand (missing …

Optimum Seeding Rate For Different Wheat Varieties In Kansas, R. Lollato, G. Cramer, A. K. Fritz, G. Zhang

Kansas Agricultural Experiment Station Research Reports

Seeding rate is an important management practice affecting wheat yield. Wheat varieties differ in their tillering capacity and therefore in their yield response to seeding rate. Our objectives were to evaluate the tillering and yield response of different modern wheat varieties to seeding rate. The study was conducted in Hutchinson and Manhattan, KS, during the 2015-16 growing season. Seven wheat varieties (Everest, KanMark, 1863, Joe, Tatanka, Larry, and Zenda) were sown at five different seeding rates (0.6, 0.95, 1.3, 1.65, and 2 million seeds per acre). Tiller number and grain yield were measured in the spring. Increasing plant population decreased …

Tillage And Nitrogen Placement Effects On Yields In A Short-Season Corn/Wheat/ Double-Crop Soybean Rotation, D. W. Sweeney

Kansas Agricultural Experiment Station Research Reports

In 2016, adding nitrogen (N) greatly improved average wheat yields, but the response to tillage and different N placement methods was minimal. Double-crop soybean yields were unaffected by tillage or the residual from N treatments that were applied to the previous wheat crop.
