Buzzworthy Messaging: Assessing Residents’ Perceptions Of Labels To Better Promote Pollinator Gardening, Colby J. Silvert, Laura A. Warner, Cody Gusto, John M. Diaz, Rachel E. Mallinger

Journal of Extension

Consumers appear more likely to purchase plants with labeling indicating pollinator-friendly production or high pollinator resource value. No standardized label for pollinator-supporting plants or landscape practices exists in the United States, which has proliferated the variety of labels used by the industry. This mixed-methods study aims to provide insight into residents’ preferred pollinator-related labelling for plants and landscape practices in order to help Extension professionals and green industry stakeholders improve outreach, marketing, and communications efforts. Findings suggest a butterfly-friendly label would be most effective for marketing while residents would accept and favorably perceive labels emphasizing either pollinator-friendly or bee-friendly attributes.

Abstract

Bermudagrass (Cynodon spp. Rich) is a warm-season grass that is widely planted throughout tropical, sub-tropical, and even temperate climates, and it generally requires fewer inputs than most cool-season turfgrasses. In recent years, the area of adaptation for bermudagrass has progressively expanded to cooler climates due to the development of more cold-tolerant cultivars. The expanded area of adaptation as well as the reduced inputs required to maintain healthy turfgrass have made bermudagrass a popular choice in areas of marginal adaptation. In these areas, the greatest threat to bermudagrass health and survivability is winterkill. This management guide seeks to describe …

Association Mapping Of Important Agronomic Traits In Mucuna Pruriens (L.) Dc., Patrush Lepcha, Mahesh Shekhar, Leelambika Murugesan, Mahammad Jaheer, Ratan Chopra, Vikas Belamkar, Narayana Sathyanarayana

Department of Agronomy and Horticulture: Faculty Publications

Background The tropical legume Mucuna pruriens (L.) DC. can meet three agricultural needs: low-cost protein, highvalue medicines, and green manure or cover crops. But like other underutilized crops, it needs more modern breeding resources. Identifying marker-trait associations (MTAs) can facilitate marker-assisted breeding and crop improvement. Recent studies have demonstrated the feasibility of identifying MTAs using a small number of accessions (< 100). We have characterized a panel of 70 M. pruriens accessions across two consecutive years and performed association analysis for 16 phenotypic traits related to seed (seed length, seed width, seed thickness, seed yield per plant, hundred seed weight); pod (pod length, pod width, number of pods …

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.

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 …

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, …

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.
