Development And Validation Of A Predictive Statistical Model To Optimize Accelerated Solvent Extraction Of Isoflavones From Edamame Soybean [Glycine Max (L.) Merrill], Yu-Ting Hung
Masters Theses
Three experiments were conducted to develop and validate predictive statistical models for isoflavone extraction from edamame soybean [Glycine max (L.) Merrill]. Soybean line NUTRIVEG Soy6407 was chosen to be the experimental sample material. The first set of extractions tested five factors; solvents, temperatures, pressures, extraction time per cycle and number of extraction cycles. Least squares means for six observed isoflavones (daidzin, glycitin, genistin, malonyl daidzin, malonyl glycitin and malonyl genistin) were used to evaluate trends for the effect of changes in each treatment factor. Pressures had no significant differences for any of the isoflavone extractions. Therefore, 500psi (the lowest pressure …
Soil And Plant Monitoring Of Nitrogen As Management Tools For Nitrogen Fertilization And Tsna Reduction In Burley Tobacco, William Hunter Frame
Soil And Plant Monitoring Of Nitrogen As Management Tools For Nitrogen Fertilization And Tsna Reduction In Burley Tobacco, William Hunter Frame
Masters Theses
Burley tobacco (Nicotiana tabacum L.) has historically been fertilized with high nitrogen rates. This study was conducted to evaluate the effect of nitrogen rate on yield and total tobacco specific nitrosamine (TSNA) concentration. The experiment also evaluated the use of in season nitrogen monitoring techniques and how well they were able to predict yield and total TSNA concentration. In 2007, five preplant nitrogen treatments along with two sidedress nitrogen treatments were used. These included: 0, 67, 135, 202, 270 kg/ha nitrogen preplant and 0 and 67 kg/ha nitrogen sidedress. In 2008, there were only four preplant nitrogen rates with the …
Efficacy Of Aryloxyphenoxypropionate Herbicides Tank-Mixed With Triclopyr For Selective Bermudagrass Control In Zoysiagrass Fairways, Dustin Franklin Lewis
Efficacy Of Aryloxyphenoxypropionate Herbicides Tank-Mixed With Triclopyr For Selective Bermudagrass Control In Zoysiagrass Fairways, Dustin Franklin Lewis
Masters Theses
Bermudagrass (Cynodon dactylon (L.) Pers.) is a difficult weed to control in Zoysia spp. fairways. Aryloxyphenoxypropionate (AOPP) herbicides, commonly referred to as graminicides, have been used in various turfgrass settings for controlling bermudagrass contamination; however, applications of these materials can injure zoysiagrass. Research has indicated that zoysiagrass injury can be reduced when multiple AOPP herbicides are tank-mixed with triclopyr, a synthetic auxin. Experiments evaluated the efficacy and safening of several AOPP herbicides when tank-mixed with triclopyr for bermudagrass control in several Zoysia spp. fairways. Experiments were also conducted to determine the response of bermudagrass and Zoysia spp. to varying application …
Evaluation Of Spring And Fall Burndown Application Timings On Control Of Glyphosate-Resistant Horesweed In No-Till Cotton, Lucas Neil Owen
Evaluation Of Spring And Fall Burndown Application Timings On Control Of Glyphosate-Resistant Horesweed In No-Till Cotton, Lucas Neil Owen
Masters Theses
Field studies were conducted in 2007 and 2008 to evaluate fall applications of herbicides to control GR horseweed prior to planting cotton. Fall treatments were compared with spring treatments for control of GR horseweed and effect on seed cotton yield. Fall and spring treatments with and without residual herbicides were also compared. No differences were observed for control of GR horseweed or seed cotton yield for both fall and spring application timings. However, a difference was observed between fall applications with and without a residual herbicide. Fall applications that contained residual herbicides provided 86% control of GR horseweed and yielded …
