Aphid Herbivory On Industrial Hemp, Cannabis Sativa L., And The Impact Of Plant-Soil Feedbacks On Hemp Performance In Louisiana, Alex Leede
LSU Master's Theses
Industrial hemp, Cannabis sativa L., is defined as having less than 0.3% delta-9-tetrahydrocannabinol by dry weight. It can be grown for fiber, food, oil, and cannabinoids. As a newly legalized crop, little research exists regarding the cultivation or pest management practices in Louisiana. The versatility of industrial hemp may allow for substantial future production in Louisiana. This project set out to understand the impact of previous crops on hemp performance and soil microbial communities. Soybean, Glycine max L. (Merr), grain sorghum, Sorghum bicolor (L.) Moench, and sweetpotato, Ipomeae batatas (L.) Lam, were selected as soil conditioning crops because they are …
Agricultural Education Teachers' Perceptions And Use Of Environmental Education In Louisiana Schools, Olivia M. Soler
Agricultural Education Teachers' Perceptions And Use Of Environmental Education In Louisiana Schools, Olivia M. Soler
LSU Master's Theses
The purpose of this study was to describe the status of environmental education (EE) in Louisiana high school agriculture classrooms. A census of Louisiana Agriscience Teacher Association (LATA) members was conducted to understand their perceptions, attitudes, and barriers regarding EE implementation. Icek Ajzen’s Theory of Planned Behavior was utilized as the theoretical framework. Data were collected through an online survey research method and analyzed using descriptive statistics. Results suggest that most LATA members incorporate EE into their curriculum relatively sparingly, perceive EE to be beneficial for students, and are in need of funding to incorporate EE into their curriculum as …
Evaluation Of Growth Characteristics, Yield, Marketability And Nitrate Levels Of Lettuce (Lactuca Sativa L) Cultivars Produced In South Louisiana, William D. Afton
Evaluation Of Growth Characteristics, Yield, Marketability And Nitrate Levels Of Lettuce (Lactuca Sativa L) Cultivars Produced In South Louisiana, William D. Afton
LSU Master's Theses
Lettuce (Lactuca sativa L.) is an important leafy vegetable crop grown in worldwide food systems with the United States ranking second behind China in total production. In 2009 the USDA Food Economic Research Service reported 1,057,715 hectares of lettuce grown in the world. Lettuce is a common market crop grown across the United States. Nitrate (NO3-) accumulation in lettuce and other leafy vegetables has been found to be a potential health threat and when consumed by humans, potentially causing methaemoglobinaemia and other diseases. There are four main types of lettuce and numerous cultivars within each type. Fresh …
Impact Of Pre-Bloom Square Loss On Yield And Lint Quality In Louisiana Cotton Cropping Systems, Cory L. Cole
Impact Of Pre-Bloom Square Loss On Yield And Lint Quality In Louisiana Cotton Cropping Systems, Cory L. Cole
LSU Master's Theses
During the 2016 growing season, research was conducted at three locations in the state of Louisiana to evaluate the impact of pre-bloom square loss on cotton lint yield and fiber quality. Two cotton varieties, Phytogen 499 WRF and Phytogen 222 WRF were chosen up which to imitate early season square loss due to tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) and/or cotton fleahopper, Pseudatomoscelis seriatus (Reuter) feeding or unfavorable weather conditions. Thirty plants within each plot were selected and squares were counted. Squares were assigned numbers, and numbers were then randomized using a computerized number generator. To simulate intervals …
Stochastic Trends In Crop Yield Density Estimation, David I. Maradiaga
Stochastic Trends In Crop Yield Density Estimation, David I. Maradiaga
LSU Master's Theses
The search for improved methods of estimating crop yield density functions has been a theme of recurrent research interest in agricultural economics. Crop yield density functions are the statistical instrument that generates probability estimates of yield risk, and risk is an important decision variable in production agriculture. Recent research in crop yield density estimation suggests that yield probability estimates can be sensitive to the way yield data are filtered, and if true, then the search for an “adequate filter” is warranted. Such a quest is pursued in this study. It is proposed that unit-root tests can be used to identify …
Determination Of The Economic Optimal Cycle Length For Major Sugarcane (Saccharum Spp.) Varieties In Louisiana, Juan Steer Nunes
Determination Of The Economic Optimal Cycle Length For Major Sugarcane (Saccharum Spp.) Varieties In Louisiana, Juan Steer Nunes
LSU Master's Theses
The general objective of the study was to determine the economically optimal crop cycle length for major sugarcane varieties currently being produced in Louisiana. The specific objectives of the project included the specification of the mathematical acreage relationships which directly impact the production of a vegetatively propagated perennial crop in a whole farm context; the development of producer decision rules to be used to determine breakeven sugar levels on third stubble sugarcane crops for major varieties in the state; the evaluation of the impact of changes in production factors on developed crop replacement rules; and the optimal cycle length for …
Economic Evaluation Of Potential Changes In Farm Program Price Support For Typical Louisiana Rice And Cotton Farming Operations, Manuel E. Aldana
Economic Evaluation Of Potential Changes In Farm Program Price Support For Typical Louisiana Rice And Cotton Farming Operations, Manuel E. Aldana
LSU Master's Theses
Increased government deficit has led the congress to reduce federal spending. Proposed budget cuts are intended to decrease government spending in several areas, including agriculture. Reductions in farm program spending could cause significant adverse effects on the financial situation of many farms, particularly to rice and cotton enterprises, due to their high reliance on farm program payments as a source of income. Representative rice and cotton operations of one, two, three, and four entities as single crop enterprises were considered and developed for use in this study. Farm enterprise sizes were determined by estimating the acreage level at which a …
