Effects Of Solid Matrix One-Step Planting Practice On Cool Season Turfgrass Germination In Unfavorable Conditions, Ben Duncan Apr 2021

Effects Of Solid Matrix One-Step Planting Practice On Cool Season Turfgrass Germination In Unfavorable Conditions, Ben Duncan

Masters Theses & Specialist Projects

The transition zone in the United States is a difficult area to grow and establish turfgrasses. To establish or repair damaged turfgrass areas, seed priming is an often-used practice. Turfgrass companies and researchers are expanding the practice of solid matrix priming to the practice of one step planting. These products contain seed, fertilizers, and often some type of inert matter and/or mulch. This study took place in Bowling Green, KY and Knoxville, TN during the same period to investigate the effects of using these one step planting products compared to standard cool season turfgrass seeding practices. Two Pennington and two …


Maize Nitrogen Management Using Reactive Sensor And Proactive Maize-N Model Via Fertigation, Mohammed Abdulridha Naser Apr 2021

Maize Nitrogen Management Using Reactive Sensor And Proactive Maize-N Model Via Fertigation, Mohammed Abdulridha Naser

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

Applying a portion of total nitrogen (N) during the growing season has the potential to improve nitrogen use efficiency (NUE) by achieving greater synchrony between N supply and crop N demand, allowing for responsive adjustments to actual field conditions. Three studies from 2017-2019 evaluated using reactive sensor and proactive Maize-N model for determining in-season N requirements via fertigation in corn. The first study evaluated the integration of reactive sensor and proactive Maize-N model for determining the timing and rate of in-season N via fertigation. Overall, reactive and proactive fertigation treatments reduced total N applied by 35 to 65 kg N …


The Influence Of Adjuvants On Physical Properties, Droplet-Size, And Efficacy Of Glufosinate And Dicamba Plus Glyphosate Solutions, Estefania Gomiero Polli Apr 2021

The Influence Of Adjuvants On Physical Properties, Droplet-Size, And Efficacy Of Glufosinate And Dicamba Plus Glyphosate Solutions, Estefania Gomiero Polli

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

Adjuvants are used in agriculture to improve herbicide activity or application performance. The addition of adjuvants to herbicide solution can enhance its penetration, wettability, and evaporation rates by altering density, viscosity, contact angle between the droplet and plant surface, and droplet surface tension. Furthermore, those alterations in the physical properties of the herbicide solution can result in changes in the droplet-size distribution that directly impact herbicide efficacy. The adoption of glufosinate-based herbicide programs has increased with the widespread occurrence of glyphosate-resistance (GR) weeds in recent years. Also, tank mixture of dicamba and glyphosate has been largely adopted for broad-spectrum weed …

Comparing A Mixed Model Approach To Traditional Stability Estimators For Mapping Genotype By Environment Interactions And Yield Stability In Soybean [Glycine Max (L.) Merr.], Mary M. Happ, George L. Graef, Haichuan Wang, Reka Howard, Luis Posadas, David L. Hyten Mar 2021

Comparing A Mixed Model Approach To Traditional Stability Estimators For Mapping Genotype By Environment Interactions And Yield Stability In Soybean [Glycine Max (L.) Merr.], Mary M. Happ, George L. Graef, Haichuan Wang, Reka Howard, Luis Posadas, David L. Hyten

Department of Agronomy and Horticulture: Faculty Publications

Identifying genetic loci associated with yield stability has helped plant breeders and geneticists begin to understand the role and influence of genotype by environment (GxE) interactions in soybean [Glycine max (L.) Merr.] productivity, as well as other crops. Quantifying a genotype’s range of performance across testing locations has been developed over decades with dozens of methodologies available. This includes directly modeling GxE interactions as part of an overall model for yield, as well as methods which generate overall yield “stability” values from multi-environment trial data. Correspondence between these methods as it pertains to the outcomes of genome wide association studies …


The Role Of Α-Tocopherol In Mitigating The Effect Of Elevated Co2 Concentrations Emitted From The Al-Hunay Power Plant Main Station On Glycine Max L. Plants, Mohammed Abdulrahman Almuwayhi Mar 2021

The Role Of Α-Tocopherol In Mitigating The Effect Of Elevated Co2 Concentrations Emitted From The Al-Hunay Power Plant Main Station On Glycine Max L. Plants, Mohammed Abdulrahman Almuwayhi

The Philippine Agricultural Scientist

Soybean (Glycine max L.), belonging to Leguminosae, is an essential food in Asian countries. It has become a necessity to study the long-term effects of elevated concentrations of CO2 on plant growth and development. Climate change may be affected by the increment of CO2 and higher temperatures on crops. Elevated concentrations of atmospheric CO2 can negatively affect the yield as well as the quality of the field crops. Alpha-tocopherol is the major vitamin E compound found in leaf chloroplasts. This antioxidant deactivates photosynthesis-derived reactive oxygen species and prevents the propagation of lipid peroxidation by scavenging lipid …


Effect Of Hydrogen Peroxide On Physiological Quality And Germination Of Aged Pumpkin Seeds Under Drought Stress Condition [Research Note], Hossein Reza Rouhi, Mohammad Hasan Vafaei, Maryam Saman, Ali Abbasi Surki Mar 2021

Effect Of Hydrogen Peroxide On Physiological Quality And Germination Of Aged Pumpkin Seeds Under Drought Stress Condition [Research Note], Hossein Reza Rouhi, Mohammad Hasan Vafaei, Maryam Saman, Ali Abbasi Surki

The Philippine Agricultural Scientist

The physiological quality of seeds decreases during their storage under unfavourable conditions. These deteriorated seeds exhibit a poorer performance, especially under stress conditions. A factorial experiment was conducted to investigate the effects of H2O2 on the germination of aged pumpkin seeds under drought stress. Hydroprimed seeds and also the seeds pre-treated with 100, 200, and 400 μM H2O2 were exposed to drought (0, -0.2, -0.4, and -0.6 MPa applied using PEG). Under drought conditions, seeds primed with H2O2 showed improved germination percentages and rates, higher vigour index, greater plumule and radicle …

Soil Erosion Modelling: A Bibliometric Analysis, Nejc Bezak, Matjǎz Mikǒs, Pasquale Borrelli, Christine Alewell, Dinesh Panday, Panos Panagos, 59 Co-Authors

Department of Agronomy and Horticulture: Faculty Publications

Soil erosion can present a major threat to agriculture due to loss of soil, nutrients, and organic carbon. Therefore, soil erosion modelling is one of the steps used to plan suitable soil protection measures and detect erosion hotspots. A bibliometric analysis of this topic can reveal research patterns and soil erosion modelling characteristics that can help identify steps needed to enhance the research conducted in this field. Therefore, a detailed bibliometric analysis, including investigation of collaboration networks and citation patterns, should be conducted. The updated version of the Global Applications of Soil Erosion Modelling Tracker (GASEMT) database contains information about …
