Pests Of Hemp In Utah, Marion Murray, Macahl Evans, Claudia Nischwitz, Austin Taylor, Cody Zesiger Dec 2022

Pests Of Hemp In Utah, Marion Murray, Macahl Evans, Claudia Nischwitz, Austin Taylor, Cody Zesiger

All Current Publications

This guide includes information on insect and disease pests of hemp, organized by pest group. Much of the content is a result of a two-year arthropod and plant disease survey of field-grown hemp operations in northern Utah. Some pests included in this guide were not found in that survey but may be likely to occur in the future. Beneficials and natural enemies are also covered, and information on pesticides is included.


Adapting Network Theory For Spatial Network Externalities In Agriculture: A Case Study On Hemp Cross-Pollination, Jeffrey S. Young, Tanner J. Mccarty Dec 2022

Adapting Network Theory For Spatial Network Externalities In Agriculture: A Case Study On Hemp Cross-Pollination, Jeffrey S. Young, Tanner J. Mccarty

Faculty & Staff Research and Creative Activity

Growers have increasingly expressed frustration over the negative externalities created by their neighbor's production practices. These spatial agricultural network problems include issues such as cross-pollination and herbicide drift. We develop novel methods for estimating parameters that allow us to adapt and apply general network diffusion models to these spatial agricultural network problems. Doing so allows us to calculate externality damage within a region and calculate cost-effective policies for alleviating that externality. We empirically illustrate, motivate, and test this approach by applying it to hemp. We find that network structure is an important factor in externality size and cost-effective policy response …


Impact Of Far-Red Light Supplementation On Yield And Growth Of Cannabis Sativa, Thomas Benjamin Carter May 2022

Impact Of Far-Red Light Supplementation On Yield And Growth Of Cannabis Sativa, Thomas Benjamin Carter

Masters Theses

Far-red light(700-780nm) induces shade avoidance response in many different species of plants. The shade avoidance response triggers a number of changes in the plant such as cell expansion and stem elongation. This cell expansion has shown to increase yields in leafy greens and increase flower set in tomatoes. Despite there being a void in the literature for Cannabis sativa, far-red lights are often advertised to provide several benefits. This study will evaluate the effects of far-red light supplementation on the yield and height of Cannabis sativa. Five cannabis clones were grown under white (410-730nm) light emitting diodes (LED’s) at …


2020 Hemp Flower Plant Spacing X Planting Date Trial, Heather Darby, John Bruce, Ivy Krezinski, Rory Malone, Sara Ziegler Mar 2022

2020 Hemp Flower Plant Spacing X Planting Date Trial, Heather Darby, John Bruce, Ivy Krezinski, Rory Malone, Sara Ziegler

Northwest Crops & Soils Program

Hemp is a non-psychoactive variety of cannabis sativa L. Hemp is a crop of historical importance in the U.S. and re-emerging worldwide as a popular crop as it is sought out as a renewable and sustainable resource for a wide variety of consumer and industrial products. Hemp that is grown for fiber, grain oil, or as an intended health supplement contains less than 0.3% tetrahydrocannabinol (THC). When hemp is grown to produce cannabidiol (CBD) as an intended health supplement, CBD concentrations are relatively high, with concentrations ranging between 8-15%. Hemp for CBD production is grown more intensively, similar to vegetable …


Cultivation Of Industrial Hemp On And Near Airports: Implications For Wildlife Use And Risk To Aviation Safety, Bradley F. Blackwell, Page E. Klug, Lee A. Humberg, Zachary T. Brym, Bryan M. Kluever, Jennifer M. Edwards Jan 2022

Cultivation Of Industrial Hemp On And Near Airports: Implications For Wildlife Use And Risk To Aviation Safety, Bradley F. Blackwell, Page E. Klug, Lee A. Humberg, Zachary T. Brym, Bryan M. Kluever, Jennifer M. Edwards

Human–Wildlife Interactions

Land-use planning on and near airports should consider possible revenue from land covers, associated maintenance costs, and potential for land covers to attract vertebrate species recognized as hazardous to aviation safety. The U.S. Federal Aviation Administration has expressed interest in recent attention given to industrial hemp (Cannabis sativa L.; hemp) as a revenue-producing land cover that might be cultivated on or near airports. Our purpose was to better understand the potential production value of hemp as well as its possible role in affecting aviation safety if cultivated on or near airports. Our objectives were to: (1) review the literature …


Hemp In The United States: An Analysis Of Policy And Consumption, Amanda Falkner Jan 2022

Hemp In The United States: An Analysis Of Policy And Consumption, Amanda Falkner

Graduate College Dissertations and Theses

As highlighted by its history, the association between hemp and marijuana has proven to be a barrier to success for industrial hemp production for decades. Once a prevalent agricultural crop in the United States, prohibitive legislation discouraged its production and formally made hemp an illegal crop in 1970. Consequently, hemp and its myriad applications remained underutilized by the United States for over forty years. It wasn’t until the 2014 Farm Bill that hemp production was reintroduced as an option for farmers. This hemp hiatus has created the need for interdisciplinary research in order for the market for the crop to …
