The Impact Of Hemp Cropping Systems On Soil Quality In Western Kentucky, Jack Eaker Nov 2020

The Impact Of Hemp Cropping Systems On Soil Quality In Western Kentucky, Jack Eaker

Scholars Week

Recently, hemp farming systems are increasingly popular in Kentucky replacing tobacco cropping systems. However, the study on the impacts of hemp cropping on soil properties is rarely conducted, resulting in limited data on soil’s behavior/changes under these management practices. Therefore, the objective of this study was to determine soil characteristics including compaction, acidity level, moisture level, and water retention. The measurements were collected from three different hemp fields, three crop rotation studies ( in 2020 - corn, soybean and tobacco) and a bare field adjacent to these fields. All fields are located at Murray State University West Farm, Calloway County, …


Seed Quality And Dormancy Of Hemp (Cannabis Sativa L.), Sabry G. Elias, Yea-Ching Wu, David C. Stimpson Nov 2020

Seed Quality And Dormancy Of Hemp (Cannabis Sativa L.), Sabry G. Elias, Yea-Ching Wu, David C. Stimpson

Journal of Agricultural Hemp Research

Hemp has great potential as cash crop for growers in the US because of its multiple uses in food, pharmaceutical, and industrial products. Seed quality and dormancy research had been put off for decades. The indeterminate flowering pattern of hemp results in harvesting seeds with varying maturity levels, affecting their quality. The objectives of this study were to: 1) investigate the differences in quality of seeds harvested from different locations on the same plant, 2) determine suitable viability and vigor tests for evaluating hemp seeds, and 3) examine the extent of dormancy in newly harvested seeds and develop a dormancy-breaking …


Evaluating The Impact Of Common Fertilizers On Soil Properties After Planting Tomatoes And Marigolds, Rachel Stuckey, Iin Handayani Nov 2020

Evaluating The Impact Of Common Fertilizers On Soil Properties After Planting Tomatoes And Marigolds, Rachel Stuckey, Iin Handayani

Scholars Week

There are many name brand fertilizers that are used today in gardening in the state of Kentucky. Due to the standardization of name brand fertilizer production in factories, this can cause the fertilizers to compromise the nutrients of soil, while all-natural fertilizers are seen as better quality for the consumers, plants and soils. Alaska, Miracle Grow, Monty’s, Pure Gold, Tiger Bloom are the top five fertilizers sold in the state of Kentucky. This study aims to determine the impact of five top commercial fertilizers on soil quality indicators including organic matter, acidity level and moisture content. These fertilizers were applied …


Soil Organic Carbon Fractions In Oil Palm Management Systems, Iin Handayani, Happy Widiastuti, Mark S. Coyne, Sri Widawati Oct 2020

Soil Organic Carbon Fractions In Oil Palm Management Systems, Iin Handayani, Happy Widiastuti, Mark S. Coyne, Sri Widawati

Faculty & Staff Research and Creative Activity

Conversion of deforested areas into oil palm plantation has been suggested as a means to improve soil quality and carbon sequestration capacity in forest margin areas. Soil organic carbon fractions, such as particulate organic carbon is the most sensitive indicator in improving soil organic matter and soil quality. We determined particulate organic matter - carbon (POM-C) and mineral associated carbon (MAC) in Bengkulu and West Java Provinces Indonesia. The study areas were grain crop fields, secondary forest, 5 yr-oil palm plantation, 10 yr-oil palm plantation, 15 yr-oil palm plantation and 25 yr-oil palm plantation. Soil organic carbon fraction magnitudes varied …


Low Income And Access To Healthy Food: The Case Of Milk, Jeffrey Young, James K. Binkley Jun 2020

Low Income And Access To Healthy Food: The Case Of Milk, Jeffrey Young, James K. Binkley

Faculty & Staff Research and Creative Activity

Even with abundant dietary research and knowledge about healthy eating, there is still a considerable shortfall in dietary quality of low-income households in the US. Chen et al. (2012) proposed that this problem is at least in part due to low-income individuals’ having less expected future earnings and thus, reduced incentive to pursue longevity by means of healthy eating. We further their analysis, offering improvement by controlling for access to low-fat milk. We find that even when allegedly crucial factors such as cost and access are not issues, relative purchasing of low-fat milk is still linked to higher income.


The Business Of Hemp In North Carolina: Where The Rubber Meets The Road, Obed Quaicoe, Fafanyo Asiseh, Omoanghe S. Isikhuemhen May 2020

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 …


Germination And Early Seedling Growth Of Vegetables Under Various Salinity Stresses, Waqas Ahmad, Muhammad Haider Ali, Iin P. Handayani Dr., Brian Parr Dr. Mar 2020

Germination And Early Seedling Growth Of Vegetables Under Various Salinity Stresses, Waqas Ahmad, Muhammad Haider Ali, Iin P. Handayani Dr., Brian Parr Dr.

Scholars Week

Vegetables are an important part of our daily diet. As salinity levels in soil and irrigation water have increased, biomass production of horticultural crops has been reduced during the past few years. The main objective of this study was to check the effect of different salinity levels (0mM, 25mM, 50mM, 100mM, 200mM NaCl) on the germination percentage and the growth rate of young seedlings of vegetables (tomato, turnip, onion, fenugreek and cauliflower) comprehensively. This experiment was designed through Factorial under Completely Randomize Design (CRD) and the results were analyzed through all Pair-wise comparison of means using Tukey test (P ≤ …


Incorporation Of Hempseed In The Broiler Chicken Diet, Mallorie Alexzandra Snider Jan 2020

Incorporation Of Hempseed In The Broiler Chicken Diet, Mallorie Alexzandra Snider

Murray State Theses and Dissertations

Hempseed has become a popular supplement alternative due to the confounding nutritional benefits it possesses; however, the legality of hempseed, and other hemp products, prevents the use in animal feeds. Particularly, broiler chickens that grow fairly quickly in a short amount of time. Evaluation of hempseed in the broiler chicken diet is needed to conclude if it is a possible replacement for other broiler nutrient sources, such as soybean meal (SBM). Thus, the objective of this study was to evaluate the effects of hempseed (HS) on the growth, feed conversion and carcass yield of broilers. This study consisted of 48 …


Impact Of Teacher Training Programs In Georgia On The Self-Efficacy Of Agricultural Education Teachers In Their First Year, Catrina Pollard, Catrina Pollard Jan 2020

Impact Of Teacher Training Programs In Georgia On The Self-Efficacy Of Agricultural Education Teachers In Their First Year, Catrina Pollard, Catrina Pollard

Murray State Theses and Dissertations

Teacher self-efficacy is directly tied to teacher longevity. The researcher conducted a causal comparative study to determine self-efficacy in three domains: classroom, FFA, SAE and compared them with demographic characteristics, along with where teachers obtained their teacher training/certification. The purpose of this study was to determine the relationship between agricultural teacher self-efficacy and the teacher preparation programs that they completed. This surveyed first-year teachers within the state of Georgia that teach agricultural education. The Beginning Agriculture Teacher Assessment determined that there was no connection between teacher self-efficacy and the teacher preparation program. The Beginning Agriculture Teacher Assessment did conclude that …
