Exploring Cover Crops for Managing Plant-Parasitic Nematodes Heterodera Glycines and Pratylenchus Penetrans
(North Dakota State University, 2022)Three studies were conducted to assess the effects of cover crops on plant-parasitic nematodes (PPNs) of potato and soybean. The first study investigated the hosting and population reduction abilities of 25 cover crops to ... -
Single-seed Descent, Single-pod Descent, and Bulk Methods in Soybean
(North Dakota State University, 2011)Soybean [Glycine max (L.) Merr.] breeders need to use the most efficient and inexpensive method to advance populations during the inbreeding process. Most breeders in the soybean industry prefer the bulk method because ... -
Salinity Tolerance of Tall Fescue (Festuca arundinacea Schreb.)
(North Dakota State University, 2011)Tall fescue (Festuca arundinacea Schreb.) is one of the commonly used cool-season turfgrass species. Despite the many advantages of tall fescue, there are some properties that restrict its use as turf grass. Recent efforts ... -
Subsurface Drainage in Clay Soils in a Northern Climate and its Effects on Various Soybean Cultivars and Soil Properties
(North Dakota State University, 2011)The Red River Valley of the North in North Dakota and Minnesota is a region with unique clay soils. Since 1993, the region has seen increased annual rainfall that has caused seasonal soil waterlogging, inhibiting crop ... -
Efficacy and Soil Residual of Herbicides Developed For Optimum GAT (Glyphosate Acetolactate Synthase Tolerant) Crops
(North Dakota State University, 2011)Field experiments were conducted at five Northern Midwest locations to evaluate one and two pass herbicide programs developed for weed control in Optimum GAT (Glyphosate Acetolactate Synthase Tolerant) corn (Zea mays ... -
Assessment of Bacterial Blight Pathogens Prevalent on Dry Bean and Identification of Sources of Resistance to Rhizoctonia Root Rot in North Dakota
(North Dakota State University, 2011)Bacterial blights and root rots are two major diseases affecting dry edible bean (Phaseolus vulgaris L.) production in North Dakota and Minnesota (Venette and Lamey 1998). Bacterial blights of dry bean are commonly caused ... -
Study of Freezing Tolerance After Cold Acclimation Followed by Deacclimation in Winter and Spring Canola (Brassica napus L.)
(North Dakota State University, 2022)Winter canola/rapeseed (Brassica napus L.) produced 20 to 30% greater yield over spring canola. It overwinters to flower in spring. The winter type shows increased freezing tolerance after cold acclimation, which is crucial ... -
Genome Wide Association Study of Basic Fruit Chemistry in the Cold Climate Wine Grapes (Vitis spp.)
(North Dakota State University, 2022)To overcome some of these challenges posed by ND climate, the utilization of native wild Vitis-derived varieties is the best possible option available. Despite advantageous environmental tolerances of native wild Vitis ... -
Comparison and Standardization of Wheat Pre-Harvest Sprouting Screening Methods, Preliminary Screening of Genomic Panel Lines
(North Dakota State University, 2022)Preharvest sprouting (PHS) in spring wheat (Triticum aestivum, L.) is a significant problem in the United States, with many ways to evaluate it. When unharvested wheat begins to sprout, the grain begins to germinate reducing ... -
Soybean Iron Deficiency Chlorosis and Amaranthus Suppression by an Oat Companion Crop
(North Dakota State University, 2022)Iron Deficiency Chlorosis (IDC) and weedy Amaranthus species are two production challenges affecting soybean production in North Dakota. Field experiments were conducted to evaluate the effect of an oat companion crop on ... -
Kentucky Bluegrass Establishment Under Saline, Waterlogging, and Saline-Waterlogging Conditions
(North Dakota State University, 2022)Kentucky bluegrass (Poa pratensis L.) (KBG) is commonly used for golf fairways, however, it is sensitive to salinity and waterlogging. The objectives of this research were to determine (1) KBG growth response to saline, ... -
Non-Chemical Weed Management in Annual and Perennial Organic Cropping Systems
(North Dakota State University, 2022)Weedy pests, especially perennial weeds, are among the most challenging barriers to organic crop production. Improving non-chemical weed management tactics for established organic productions systems, like cool-season ... -
X-Ray Induced Mutagenesis in Sunflower Pollen
(North Dakota State University, 2022)The identification of new sunflower hybrids that have desirable traits depends on the availability of adequate genetic resources. A critical part of sunflower breeding is to find and recombine genetic variability into ... -
Influence of Soil Type, Fertilizer, and Mulch Amendment in Containerized Polyculture
(North Dakota State University, 2022)There are many avenues to address global food supply and global food production increasing food security for individuals and communities. Though corporate agriculture provides the largest percentage of global sustenance ... -
Characterizing Late Blight Resistance of Parental Genotypes Used in the North Dakota State University Potato Breeding Program
(North Dakota State University, 2022)The potato is an important food crop, and late blight is a potato disease costing growers millions of dollars. Utilizing cultivars with late blight resistance is the longest-term option to manage the disease. This two-part ... -
Corn-Alfalfa Intercropping with Different Row Spacings
(North Dakota State University, 2022)Alfalfa (Medicago sativa L.) is a staple crop grown mainly by dairy and beef farmers in the Midwest. To determine if seeding alfalfa with corn (Zea mays L.) could increase alfalfa forage yield and nutritive value in the ... -
Pre-Breeding to Combine Diverse Disease Resistance and Agrotype Genes in Hard Winter Wheat
(North Dakota State University, 2022)The NDSU hard winter wheat (HWW) breeding program aims to develop improved varieties that are better equipped to cope with the environmental and disease challenges of the northern prairies. To achieve this, it is necessary ... -
Corn Hybrid Response to Skip-Row Planting Configurations and Plant Population in Western North Dakota
