A Survey Of Fusarium Oxysporum In Georgia Hemp Farms And Vegetable Gardens, Christopher D. Burt Jan 2024

A Survey Of Fusarium Oxysporum In Georgia Hemp Farms And Vegetable Gardens, Christopher D. Burt

Georgia Journal of Science

Recent changes in U.S. federal law have recognized the genetic and chemical differences between hemp and marijuana (Cannabis sativa L.), resulting in the legalization of hemp in the United States. The barriers to this plant’s growth in the state of Georgia are not well understood due to its prohibition for the past 80 years. Among the many possible obstacles is fungal disease. Fusarium oxysporum (Schlecht. emend. Snyder & Hansen) is a fungus that damages various crops and was previously researched as a biocontrol agent for C. sativa. Thus, this study surveyed hemp farms in Georgia to determine the prevalence …

Kansas Agricultural Experiment Station Research Reports

Hemp has garnered interest as a potential crop that is not constrained by the typical food, feed, and fuel market channels. Although hemp varieties are available for the production of either grain, fiber, or both (dual-purpose: both grain and fiber) markets, little research-based information is available on hemp growth and water use in Kansas environments. In 2019, Kansas State University researchers began conducting experi­ments to characterize hemp growth, nutrient uptake, and soil water depletion at three locations representing the precipitation gradient across Kansas. In 2021, one fiber and one grain variety were evaluated with and without fertilizer nitrogen. Soil water …

Hemp is a broad term used to describe the many varieties of Cannabis sativa L. that produce less than 0.3% tetrahydrocannabinol (THC). The crop is globally significant and has recently been approved in the United States. There are many uses for industrial hemp, and the market for industrial hemp is rapidly growing as more states are legalizing its production. Industrial hemp is marketed for oil, grain, and fiber. Varieties have been selected for improved fiber and grain production that can service these markets. However, little research-based information is available regarding adaptability or production of these varieties in Kansas. The objectives …


Western Bean Cutworm (Lepidoptera: Noctuidae) Feeding And Development On Industrial Hemp In The Laboratory And Field, Christina D. Difonzo Nov 2022

Western Bean Cutworm (Lepidoptera: Noctuidae) Feeding And Development On Industrial Hemp In The Laboratory And Field, Christina D. Difonzo

The Great Lakes Entomologist

The western bean cutworm (Striacosta albicosta (Smith)) is a key pest of corn (Zea mays L.) and dry beans (Phaseolus vulgaris L.). This observational study demonstrates that in addition to these hosts, western bean cutworm readily feeds on industrial hemp (Cannabis sativa L.) and completes development on it under controlled laboratory conditions. In the laboratory, individual larvae were reared on a diet exclusively of hemp inflorescences; 57% survived to form prepupae and 15% emerged as moths. In the field, first instars were caged on hemp plants to investigate larval development in situ. After seven days, 82% …

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 There It Is: Examining Consumers’ Attitudes Toward The Revitalization Of Hemp As An Agricultural Commodity, Shelli Rampold, Zachary Brym, Michaela S. Kandzer, Lauri M. Baker

Journal of Applied Communications

This study was conducted to examine Florida consumers’ stance on legalizing the growing and processing of hemp, recently redefined as an agricultural commodity. Factors were explored that may explain their stance to provide insight into the communication needs in the early stages of the U.S. hemp industry revival. Results indicated that respondents who had more favorable attitudes toward legalizing hemp were also more likely to fall within the category of being overall “for legalizing hemp” when offered a binary choice. Further, attitude toward legalizing hemp was predicted by respondents’ objective knowledge of hemp topics, attitude toward legalizing marijuana, and perceived …


Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young Feb 2021

Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young

Journal of Applied Farm Economics

The 2018 farm bill removed industrial hemp from the Schedule 1 Controlled Substance List. In response, states scrambled to enact hemp legislation. Some hemp flower producers report their hemp fields were cross- pollinated by a neighbor growing a different hemp cultivar. For hemp flower crops, cross- pollination reduces cannabinoid concentration levels within the flower; these concentration levels dictate flower price. We show that in a repeated game, once a sufficiently large percentage of growers decide to plant hemp fiber/seed crops, cross-pollination forces flower growers to convert to fiber/seed to avoid the negative network externality. Over time, a stable, suboptimal Nash …


Magnesium’S Impact On Cannabis Sativa ‘Baox’ And ‘Suver Haze’ Growth And Cannabinoid Production, Patrick Veazie, Paul Cockson, David Logan, Brian Whipker Feb 2021

Magnesium’S Impact On Cannabis Sativa ‘Baox’ And ‘Suver Haze’ Growth And Cannabinoid Production, Patrick Veazie, Paul Cockson, David Logan, Brian Whipker

Journal of Agricultural Hemp Research

Limited research exists on the fertility needs for industrial hemp (Cannabis sativa) and the impact of fertility on plant growth and cannabinoids. Optimizing floral production for cannabinoid production and especially cannabidiol (CBD) production, is an economic goal for growers. Magnesium (Mg) is an essential nutrient for plant growth and plays many key roles in plant growth and when deficient leads to suboptimal plant growth. Six Mg fertility rates (0.0, 12.5, 25.0, 50.0, 75.0, and 100.0 mg·L-1) were evaluated to determine the optimal fertility for C. sativa on two High CBD-type cultivars ‘BaOx; and ‘Suver Haze’. Foliar …


Effects Of Using Hemp Hearts As A Feed Additive In Broiler Chicks, Brian Parr, Cheyenne Hooks, Mallorie Snider, Huichang Chae, Tony Brannon Sep 2020

Effects Of Using Hemp Hearts As A Feed Additive In Broiler Chicks, Brian Parr, Cheyenne Hooks, Mallorie Snider, Huichang Chae, Tony Brannon

Journal of Agricultural Hemp Research

In this experiment, hemp hearts of differing percentages were fed to broiler chicks for 49 days. The experiment, which was initiated to identify the potential of hemp hearts as a feed source, consisted of four experimental groups and one control group. Each experimental group received a diet containing: 10%, 20%, 30% and 40% hemp hearts; the control group did not contain hemp hearts, but contained soybean meal. As a result, broilers fed a diet containing 20% hemp hearts gained the most weight, t(16) = 2.12, p < 0.05 and feed conversion was also the lowest t(18) = 2.10, p < 0.01. These results indicate the feed efficiency of broilers using 20% hemp hearts was the lowest numerically, but the most efficient qualitatively. The diets consisting of higher percentages of hemp hearts demonstrate a need for additional supplementation.

The Business Of Hemp In North Carolina: Where The Rubber Meets The Road, Obed Quaicoe, Fafanyo Asiseh, Omoanghe S. Isikhuemhen

Journal of Agricultural Hemp Research

Industrial hemp continues to receive a lot of attention in the United States of America with a projected annual revenue growth rate of 18.4 percent by 2022. The momentum industrial hemp has gathered in the past few years has made it the ‘new lucrative crop’ for people to grow. However, many farmers have jumped into hemp farming without first obtaining a realistic economic analysis of hemp farming. In this paper, we seek to review and explore the economic opportunities and challenges of hemp production as a useful guide for reducing risks and maintaining profitability for farmers in North Carolina. Our …

Practical And Theoretical Analysis Of The New Device While Preparing Cotton For Processing, M.T. Khadjiev, E.E. Gaibnazarov, Sh.Sh. Isaev

Bulletin of Gulistan State University

The article considers the cleaning efficiency of the machine in cleaning equipment from fine and large impurities of cotton seeds, the main processes in the selection of technological parameters. The main essence of the process is determined by the theoretical characteristics of reducing the strength of the bond between the waste particle and the fiber and separating it from the mass of raw materials under the influence of dynamic force.


An Assessment Of Economic Considerations For Industrial Hemp Production, Luke Lane, Jennie S. Popp, Michael P. Popp, Harrison M. Pittman Jan 2017

An Assessment Of Economic Considerations For Industrial Hemp Production, Luke Lane, Jennie S. Popp, Michael P. Popp, Harrison M. Pittman

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

United States farm policy and programs are governed by the Farm Bill. The 2014 Farm Bill allows for the legal production and research of industrial hemp as long as it meets the standards outlined in the Farm Bill. Although it has a wide range of uses (upwards of 25,000 products use hemp), there is a lack of recent information regarding the economic feasibility of hemp production for the private agricultural sector. Through an extensive search of existing literature, information was gathered to construct an enterprise budget for industrial hemp. Data from the enterprise budget were used in a constrained linear …
