Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, Shane Ylagan 2020 University of Arkansas, Fayetteville

Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, Shane Ylagan

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

The ability to recycle phosphorus (P) from wastewaters could provide a sustainable, continuous source of P that might also help protect surface water quality from P enrichment. The mineral struvite (MgNH4PO4·6H2O) is an understudied material that can be created from Pcontaining 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 super phosphate (TSP) on corn (Zea mays) and soybean (Glycine max) response in a 79-day greenhouse ...


Nodulation And Growth Of Shepherdia × Utahensis ‘Torrey’, Ji-Jhong Chen 2020 Utah State University

Nodulation And Growth Of Shepherdia × Utahensis ‘Torrey’, Ji-Jhong Chen

All Graduate Theses and Dissertations

Shepherdia ×utahensis ‘Torrey’ (Elaeagnaceae) is a hybrid of two native actinorhizal plants in the Intermountain West, S. argentea (silver buffaloberry) and S. rotundifolia (roundleaf buffaloberry). Due to actinorhizal symbiosis, atmospheric nitrogen (N2) can be converted to ammonium, a bioavailable form. Actinorhizal plants have great value in sustainable nursery production and urban landscape use. However, nitrogen fertilizer negatively affects the nodulation of actinorhizal plants. As a newly developed hybrid, both the symbiont identity and nodule formation of S. ×utahensis ‘Torrey’ remain largely unknown. Therefore, experiments were conducted to investigate the nodule formation of S. ×utahensis ‘Torrey’ inoculated with field soils ...


Selection And Propagation Of Pinyon Pine, Kylie M. Lawson 2020 Utah State University

Selection And Propagation Of Pinyon Pine, Kylie M. Lawson

All Graduate Theses and Dissertations

Single-leaf pinyon pines are drought tolerant trees native to the Great Basin. This species is a source of wild-collected, edible pine nuts that are in great demand. With no previous research apparent, this thesis aimed to identify wild trees with high cone production as sources for evaluating grafting onto immature and mature trees. Wild sources of scions were identified from four wild stands and six trees per stand. Counting and analyzing the number of scars left by mature cones along the leader branch provided an estimate for each tree’s productivity and identified trees with greater productivity within a stand ...


Examination And Empirical Forecast Of Wheat Yield In Northwest India Based On Climate And Socio-Economic Factors, Avik Mukherjee 2020 Utah State University

Examination And Empirical Forecast Of Wheat Yield In Northwest India Based On Climate And Socio-Economic Factors, Avik Mukherjee

All Graduate Theses and Dissertations

This study summarizes the findings of research organized in two parts. The first part includes the impact of climate and socio-economic factors that affected wheat yield in northwest India during the 2000s. The second part focused on the forecast of average wheat yield for the two highest wheat producing states Punjab and Haryana.

Initial study focused on the impact of climate factors on wheat yield in northwest India. It has been found that above normal temperature coupled with water shortage i.e. irregular irrigation and low soil moisture contributed to the prolonged yield reduction during 2002-2010.

Next, we reviewed the ...


Water Use In Jujube (Ziziphus Jujuba) With Applications In Irrigation Timing And Quantity, Preston S. Colver 2020 Utah State University

Water Use In Jujube (Ziziphus Jujuba) With Applications In Irrigation Timing And Quantity, Preston S. Colver

All Graduate Theses and Dissertations

Jujube (Ziziphus jujuba) is a major fruit crop in China where it has been a favored cash crop and successfully used to address erosion problems in the Loess Plateau region of western China. Further use of jujube in forestry projects and improved agricultural efficiency are very promising. This study sought to repeat a water-use study in two climates: a hot, semi-arid climate in Yangling, Shaanxi, China and a dry-summer, continental climate in Logan, Utah, USA. The study took physiological measurements on the trees with the aim of characterizing the way that jujube uses water. This would help to create an ...


Assessment Of Compost On Dryland Wheat Yield And Quality, Soil Fertility And Water Availability In Utah, Kareem A. Adeleke 2020 Utah State University

Assessment Of Compost On Dryland Wheat Yield And Quality, Soil Fertility And Water Availability In Utah, Kareem A. Adeleke

All Graduate Theses and Dissertations

In 2014-2016 Kareem Adeleke undertook a graduate project under the supervision of Utah State University (USU) Plants, Soils and Climate professors, Drs. Jennifer Reeve, Astrid Jacobson, and Earl Creech. Organic wheat producers face numerous challenges, such as low soil moisture, soil erosion, and low soil fertility. Organic wheat growers generally do not apply fertilizer due to inability to recoup the costs in the short-term. Compost enhances long-term improvement in soil quality, soil fertility and increase yield in low input environments. Understanding of compost carryover effects in dryland wheat systems is necessary for increased yield that will allow adequate supply of ...


Effects Of Wi-Fi-Enabled Smart Irrigation Controllers On Water Use And Plant Health Of Residential Landscapes In The Intermountain West, Shane R. Evans 2020 Utah State University

Effects Of Wi-Fi-Enabled Smart Irrigation Controllers On Water Use And Plant Health Of Residential Landscapes In The Intermountain West, Shane R. Evans

All Graduate Theses and Dissertations

Residential and commercial landscapes provide home and business owners with several benefits. These benefits range from improved air quality and flood control to the reduction of noise and breakdown of organic chemicals. However, these landscapes are routinely overwatered which can lead to plant disease, nutrient pollution, and large amounts of water being wasted. Utah State University, in conjunction with the Center for Water Efficient Landscaping (CWEL), the Utah Division of Natural Resources and Weber Basin Water Conservancy District, conducted an experiment to determine if Wi-Fi-enabled smart irrigation controllers conserve water as compared to average residential irrigation amounts and manually programmed ...
