Could Winter Annual Crop Choice Increase No-Till Double-Crop Soybean Yield In Kentucky?, Ethan M. Swiggart
Could Winter Annual Crop Choice Increase No-Till Double-Crop Soybean Yield In Kentucky?, Ethan M. Swiggart
Theses and Dissertations--Plant and Soil Sciences
Double-cropping soybean (Glycine max L.) after a winter annual crop is common in Kentucky. The preceding winter annual crop may affect double-crop soybean yield in Kentucky. Producers and agronomists have reported greater double-crop soybean yields when preceded by winter canola (Brassica napus L.) rather than winter wheat (Triticum aestivum L.). Explanations for these yield differences remain unresolved. The objectives of this study are to: (1) evaluate double-crop soybean productivity in field environments following four winter annual crop treatments; (2) determine differences of early soybean growth in greenhouse (GH) and cold chamber (CC) environments; and …
Increasing Renewable Oil Content And Utility, William Richard Serson
Increasing Renewable Oil Content And Utility, William Richard Serson
Theses and Dissertations--Plant and Soil Sciences
Since the dawn of agriculture man has been genetically modifying crop plants to increase yield, quality and utility. In addition to selective breeding and hybridization we can utilize mutant populations and biotechnology to have greater control over crop plant modification than ever before. Increasing the production of plant oils such as soybean oil as a renewable resource for food and fuel is valuable. Successful breeding for higher oil levels in soybean, however, usually results in reduced protein, a second valuable seed component. We show that by manipulating a highly active acyl-CoA: diacylglycerol acyltransferase (DGAT) the hydrocarbon flux to oil in …
