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 …
