"I am investigating evaluation of abiotic and biotic resistance; conduct QTL and association mapping and identify SNP markers; and study gene expression for the abiotic and biotic resistance in vegetable crops such as tomato."

My research involves looking at different strategies for controlling spring dead spot (SDS) of bermudagrass. The main focus will be to determine the best possible time to apply fungicides for maximum SDS control. Other objectives of my research will be looking at nozzle types, aerifying prior to fungicide application, as well as examining the ability of various fungicides  to control SDS over multiple growing seasons. 

"The aim of my study is to evaluate drought tolerance in tomato germplasm accessions and conduct genome-wide association study (GWAS) to identify genetic markers associated with tolerance to drought. Dr. Gehendra Bhattarai will supervise implementation of the project."

"Flowering is one of the more complex and interesting processes in plants at the molecular and physiological levels. Understanding the molecular mechanism of blackberries' flowering is fundamental to improving new genotypes in the breeding program. Therefore, part of my research is the discovery of genes involved in flowering time and intensity by combining quantitative genetics, bioinformatics, and physiology. Additionally, I am working on the implementation of molecular breeding strategies such as marker-assisted selection and genomic selection for key traits in the blackberry crop like primocane fruiting, thorniness, plant height, fruit texture, and flavor components. Successful adoption of molecular tools in the fruit breeding program will aid to accelerate the development of new cultivars."

My master's research investigates selected spinach Spinacia oleracea genotypes resistance to the plant pathogenic fungi Pythium and Aphanomyces in a model vertical farm system. The exciting and potential impactful benefit of my research is developing the novel model vertical farm system and associated growing and pathology protocols to test genotype/disease interactions using vertical farm technology. The model system and developed protocols will be useful to screen a large number of genotypes and plant species to selected plant pathogens.

My project involves evaluating the suitability of blackberry varieties for use on the rotating cross-arm trellis using novel training methods. I am looking at the influence of light exposure on plant morphology and fruit quality.

"My research focuses on updating fertility recommendations for Southeastern blackberry production.  She is evaluating nitrogen fertility rates for  ‘Ouachita’ blackberry production, refining leaf tissue nutrient sufficiency recommendations, and studying nitrogen allocation in Prime-Ark® Traveler."

"I am looking into broad mites on blackberry; more specifically, the efficiency of primocane leaflet sampling, the impact cultivars can have on broad mite populations, and the influence of broad mite feeding on yields. The ultimate goal of my research is to assist growers in making more informed miticide decisions."

My research focuses on improving our understanding of soil surfactants (a.k.a. wetting agents), and the different ways they affect water movement & availability within the rootzones of intensively managed turfgrass systems, especially those prone to hydrophobicity.

Central to this work is an effort to differentiate, organize, and classify wetting agents based on objective, scientific research data, rather than marketing claims & terminology offered by manufacturers.

Additionally, my research seeks to develop improved application strategies for maximizing the benefits of wetting agents, examining both environmental factors corresponding to reductions in product efficacy, as well as product combinations and rotations which may enhance overall effectiveness.

While my research speaks largely to the golf course industry where wetting agents are commonly used, I also have a strong interest in exploring novel situations for using wetting agents well-beyond the golf course, so that the positive attributes of healthy turfgrass may be more fully recognized and appreciated.

 

 

"My name is Sarah Paschal and I am a Turf Grass Sciences Masters student working under Dr. Mike Richardson. Together, we are working on a roadside native vegetation restoration project funded by the Arkansas Department of Transportation. This project has six locations throughout the state of Arkansas representing the different eco regions found across the state. We will be planting and collecting data on forbs, tall grass, and short grass mixtures. "

"I am a Master’s student in the Controlled Environment lab and my thesis work will look at plant nutrition for greenhouse crops grown in closed hydroponic systems. My projects will look at nutrient solution compositions as well as different replenishment methods for multiple plant species."

Seedlessness is a desired trait for fresh market muscadine grapes. Part of my research is discovering the genes involved with seedlessness in muscadine grapes by phenotyping thirteen populations and genotyping one thousand muscadine vines. Additionally, a mapping population will be used in muscadine grapes to determine genetic distances between pairs of loci for various traits, such as seedlessness, flower sex, vigor, winter injury, and more. 

"My project is on vegetation management in native grasses and wildflower plantings on roadsides and for prairie restoration. Within this project, there will be a field study and greenhouse component to screen herbicides for their effect on the native grass and forb species included in the 7 seed mixtures that are part of this project, as well as on the weeds found at the field sites."
