Trouble At Old River: An Economic Evaluation Of An Avulsion On United States Soybean Trade, Patrice Maria Lazard
Trouble At Old River: An Economic Evaluation Of An Avulsion On United States Soybean Trade, Patrice Maria Lazard
LSU Master's Theses
The Mississippi River is an essential asset to agricultural trade given that its existence contributes to a cost-efficient transportation system. Barge travel allows large amounts of soybeans and other bulk commodities to be transported at low costs. Currently, barge costs are the lowest relative to those of other modes. Although there has been increasing competition for soybean shares from other countries in the global market, low transportation costs of soybeans, grain, and other oilseed crops allow the United States to retain its competitive advantage in the world soybean market. The Mississippi River’s urgency to change course and possibly eliminate barge …
Rice Response To Nitrogen Fertilization And Comparison Of Unmanned Aerial Systems And Active Crop Canopy Sensors Vegetative Index To Estimate Rice Yield Potential, Anna Coker
LSU Master's Theses
Nitrogen (N) fertilization is a key component in producing profitable, maximized rice grain yields because yield is directly affected by N fertilizer applications. Economical optimum N rate (EONR) is used to estimate where the N fertilization rate impacts rice grain yield but is still economically efficient. Three common response models, linear-plateau, quadratic-plateau, and quadratic models were used to determine the response of rice to N fertilizer to determine the optimum N fertilization rate. The objective of the first part of this study was to evaluate the models by assessing the coefficients of determination (R2), maximum rice grain yields …
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 …
Strategies To Overcome Antagonism Of Quizalofop-P-Ethyl When Applied In Mixture With Other Herbicides, Lucas C. Webster
Strategies To Overcome Antagonism Of Quizalofop-P-Ethyl When Applied In Mixture With Other Herbicides, Lucas C. Webster
LSU Master's Theses
A field study was conducted in 2017 and 2018 at the LSU Agricultural Center H. Rouse Caffey Rice Research Station (RRS) near Crowley, LA. to evaluate the influence of different adjuvants in overcoming the antagonism of quizalofop when mixed with bispyribac in Louisiana rice production. The antagonism of quizalofop mixed with bispyribac plus HCOC at 14 DAIT was overcome with a neutral interaction observed at 28 DAIT for barnyardgrass control with an observed control of 91%, compared with an expected control of 97%. The addition of COC, SNS or HCOC into a mixture of quizalofop plus bispyribac provided synergistic or …
Investigating The Effects Of Cognitive Diversity On The Small Gasoline Engines Problem Solving Ability Of Undergraduate Students Enrolled In A Team-Based Learning Formatted Agricultural Mechanics Course, Whitney L. Figland
LSU Master's Theses
Perhaps the most challenging factor in teaching is being able to foster a learning environment that meets the needs of all learners, which is often achieved by utilizing a plethora of instructional methods that develop critical thinking and problem solving skills. These 21st century skills have been recurrently identified as a critical component of today’s workplace and employers are hiring individuals who can solve complex problems, especially within agriculture. However, students in todays educational classrooms are often not receiving the hands-on instruction that is needed in order to foster the development of critical thinking and problem solving skills. Further, problem …
