Evaluation And Improvement Of The Design 4 Every Drop Course, Kenzy Fogle

All Graduate Reports and Creative Projects, Fall 2023 to Present

Utah and the greater Intermountain West are experiencing a water crisis. Many factors are contributing to this situation, including an arid climate exacerbated by climate change, rapid population growth, and a high-water-demanding landscape typology. Landscapes currently consume an estimated 60-80% of Utah’s potable water, representing a significant opportunity for water savings. However, changing the traditional water-dependent landscape typology requires educating the public regarding water-wise landscape design processes, best practices, and implementation approaches. Utah State University is the land grant university for Utah and home to one of the oldest Landscape Architecture departments in the Intermountain West. Utah State University’s community …

Key Stages In The Growth And Maturity Of Field Pea, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Many farm operations rely on a clear understanding of the stage of crop development. This factsheet describes key growth stages of field pea, which will aid growers and their advisers in determining the appropriate timing for the application of herbicides, crop-topping, swathing, and harvest.

There is likely to be considerable variability in a crop, particularly at maturity and harvest. Therefore, it is often necessary to estimate the average or majority development stage of a crop. At first, this is best done numerically, but with experience it can be done by eye.

Factors Influencing Adventitious Root Formation Of Floral Hemp In Propagation, Alexandra Carver

All Theses

Commercial propagators have reported relatively poor propagation success, e.g., <75% rooting, for many hemp (Cannabis sativa) cultivars. These rooting percentages have a significant economic impact due to the wasted labor, space and supplies. Also, the market demands 100% of the propagation cells in a tray to be fully rooted, thus repairing and replacing poorly rooted or unrooted cuttings requires significant labor cost. The goal of this thesis was to evaluate several factors that influence adventitious root formation of hemp stem cuttings.

Chapter 2 describes an experiment conducted to identify rooting hormone treatments that could improve propagation success. Sixteen combinations of indole-3-butyric acid (IBA; 0, …

Using Machine Learning To Combine Genetic And Environmental Data For Maize Grain Yield Predictions Across Multi-Environment Trials, Igor K. Fernandes, Caio C. Vieira, Kaio O.G. Dias, Samuel B. Fernandes

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Complementing phenotypic traits and molecular markers with high-dimensional data such as climate and soil information is becoming a common practice in breeding programs. This study explored new ways to combine non-genetic information in genomic prediction models using machine learning. Using the multi-environment trial data from the Genomes To Fields initiative, different models to predict maize grain yield were adjusted using various inputs: genetic, environmental, or a combination of both, either in an additive (genetic-and-environmental; G+E) or a multiplicative (genotype-by-environment interaction; GEI) manner. When including environmental data, the mean prediction accuracy of machine learning genomic prediction models increased up to 7% …

Protected cultivation is the production of horticultural crops including vegetables under structures such as forced-ventilated greenhouses, shade net houses, poly houses, net houses, high and low plastic tunnels, where the external growing environment can be controlled or modified to suit crop growth requirements. In regions where the environmental conditions such as weather, soil and water are not suitable to grow specific vegetables, or in urban areas with limited arable land, this farming system is very important to ensure high, stable productivity and good quality vegetables. This enables a stable supply for the market all year round, bringing high economic return …

Lure Specificity, Phenology, And Damage Caused By Epiphyas Moths (Lepidoptera: Tortricidae) In Western Australian Apple Orchards, Maryam Yazdani, Elliot T. Howse, Wee Tek Tay, Helen Spafford, Rieks Van Klinken

Horticulture Research Articles

Multiple Epiphyas species inhabit southwestern Western Australia, including Light Brown Apple Moth (LBAM) Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), a globally significant, polyphagous pest. This study evaluated the efficacy and specificity of lures designed for 3 Epiphyas species: E. postvittana, Epiphyas pulla (Turner), and the undescribed Epiphyas sp. (1) (Common). Additionally, the study sought to determine the presence and distribution of Epiphyas species in 3 significant apple-growing localities. Trapping, together with partial sequencing of the mitochondrial COI gene, found LBAM to be restricted to the Perth Hills and E. pulla, to apple orchards near Manjimup and Pemberton.

Can The Necrophagous Blow Fly Calliphora Vicina (Diptera: Calliphoridae) Be Reared On Plant-Based Meal?, David F. Cook, Muhammad Shoaib Tufail, Sasha C. Voss

Horticulture Research Articles

The use of the blow fly Calliphora vicina as a potential pollination species to augment the current reliance on honeybees (Apis mellifera) in Australian horticulture requires knowledge of how best to mass-rear this fly species. Calliphora vicina lays eggs onto carrion soon after death, and the resultant larvae that hatch are necrophagous and feed on the decomposing tissues of the dead animal. Newly hatched larvae of this fly were provided with plant-based meals (soya bean and canola) and compared with larvae provided with livestock-derived meatmeal to determine if plant-based meal could be used to mass-rear this blow fly species. Both …

Greater Aperture Counteracts Effects Of Reduced Stomatal Density On Water Use Efficiency: A Case Study On Sugarcane And Meta-Analysis, Daniel Lunn, Baskaran Kannan, Amandine Germon, Alistair Leverett, Thomas E. Clemente, Fredy Altpeter, Andrew D.B. Leakey

Department of Agronomy and Horticulture: Faculty Publications

Stomata regulate CO₂ and water vapor exchange between leaves and the atmosphere. Stomata are a target for engineering to improve crop intrinsic water use efficiency (iWUE). One example is by expressing genes that lower stomatal density (SD) and reduce stomatal conductance (g_sw). However, the quantitative relationship between reduced SD, g_sw, and the mechanisms underlying it is poorly understood. We addressed this knowledge gap using low-SD sugarcane (Saccharum spp. hybrid) as a case study alongside a meta-analysis of data from 10 species. Transgenic expression of EPIDERMAL PATTERNING FACTOR 2 from Sorghum bicolor (SbEPF2) in sugarcane …

Revisiting Fr13a For Submergence Tolerance: Beyond The Sub1a Gene, Waseem Hussain, Mahender Anumalla, Abdelbagi M. Ismail, Harkamal Walia, Vistas Kumar Singh, Ajay Kohli, Sankalp Bhosale, Hans Bhardwaj

Department of Agronomy and Horticulture: Faculty Publications

Rice landrace FR13A is the original donor of the SUB1A gene. FR13A harbors hidden genetic variation that surpasses the submergence tolerance level of SUB1A. Here, we provide an overview of the unique features of FR13A associated with exceptional recovery ability that have been overlooked since the significant discovery of the SUB1 locus. We present a detailed overview of how to underpin the new genes associated with the recovery ability seen in FR13A. Finally, we propose a unique approach to develop rice cultivars that surpass submergence tolerance beyond the SUB1 locus from FR13A.

Echinacea, commonly known as coneflower, is an easy-to-grow, low-maintenance cut flower crop. As a perennial, plants can be expected to last up to 5 years in production before replacement is needed. Known for delicately arching petals and strong stems, echinacea comes in a wide range of colors that lend a wildflower look to floral design. Seed heads are also popular and can be harvested for their rust-orange cone shape.

Field Evaluation Of Female- And Male-Targeted Traps For Ceratitis Capitata (Diptera: Tephritidae), Elliot T. Howse, Rieks Van Klinken, Nicholas J. Beeton, Helen Spafford, Kim P. James, Matthew P. Hill

Horticulture Research Articles

Mediterranean fruit fly (Medfly) Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is a globally significant economic pest for which lure based trapping can be used to monitor established populations and for surveillance. Either female- or male-targeted traps can be used; however, recommendations on which to apply are inconsistent and many programs rely on male-targeted traps. Here, we compare the performance of male-targeted traps (Lynfield Trap with Trimedlure) and female-targeted traps (Biotrap Globe trap with the 3-component lure—TMA Plus) in apple orchards in south-west Western Australia over 2 years (September 2019 to September 2021). Male-targeted traps caught more Medflies overall than female-targeted traps, …
