Effect Of Chitosan On Plant Growth, Flowering, And Substrate Characteristics Of Potted Geranium (Pelargonium X Hortorum), Maggie Liu

Holster Scholar Projects

Modern industrial agricultural practices rely heavily on the use of fertilizers and pesticides to increase crop quality and quality which overtime gradually degrades the quality of cultivated soils and aquatic environments. The purpose of this project is to determine how chitosan polymers with various molecular weights affect the growth and flowering of Geranium plants as well as the water and nutrient retention capacity of the substrate. Three chitosans with different molecular weights (2 kDa, 50 kDa, and 970 Da) were experimented on the geraniums. Each chitosan treatment was applied through a spray system onto the experimental group plants after transplantation …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

Estimating The Genetic Parameters Of Yield-Related 1 Traits Under Different Nitrogen Conditions In Maize, Semra Palali Delen, Gen Xu, Jenifer Velazquez-Perfecto, Jinliang Yang

Department of Agronomy and Horticulture: Faculty Publications

Understanding the genetic basis responding to nitrogen (N) fertilization in crop production is a long-standing research topic in plant breeding and genetics. Albeit years of continuous efforts, the genetic architecture parameters, such as heritability, polygenicity, and mode of selection, underlying the N responses in maize remain largely unclear. In this study, about n = 230 maize inbred lines were phenotyped under high N (HN) and low N (LN) conditions for two consecutive years to obtain six yield-related traits. Heritability analyses suggested that traits highly responsive to N treatments were less heritable. Using publicly available SNP genotypes, the genome-wide association study …

Department of Agronomy and Horticulture: Faculty Publications

Corn resistant to aryloxyphenoxypropionates (FOPs) (Enlist™ corn) enables the use of quizalofop-p-ethyl (QPE) as a selective postemergence (POST) herbicide for control of glufosinate/glyphosate-resistant corn volunteers. Growers usually mix QPE with 2,4-D choline and/or glufosinate to achieve broad-spectrum weed control in Enlist™ corn. The objectives of this study were to (1) evaluate the efficacy of QPE applied alone or mixed with 2,4-D choline and/or glufosinate for control of glufosinate/glyphosate-resistant corn volunteers in Enlist™ corn and (2) determine the impact of application time (V3 or V6 growth stage of volunteer corn) of QPE-based treatments on volunteer corn control as well as Enlist™ …

The Biggest Grower: A Youth Gardening Competition For Growing Specialty Crops And Urban Farmers, Stacy A. Adams, Terri James

Department of Agronomy and Horticulture: Faculty Publications

Abstract

Youth today have tendencies for unhealthy lifestyles, being sedentary, consuming high fat diets low in fruits and vegetables, all contributing to child obesity, type 2 diabetes, hypertension, and precedence for life-long health concerns. For rural and economically disadvantaged urban households, poor diet is directly attributed to the inaccessibility of fresh produce, affordability and understanding of preparation of various specialty crops. Through a grant from the NE Specialty Crop Block Funding Program, The Biggest Grower Competition (BGC) was developed as a summer extension education program for youth in 8^th through 12^th grade. Project goals included; provide educational materials …

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …
