(North Dakota State University, 2018)
A study was conducted at ten locations in North Dakota and Minnesota in 2016 and 2017 to evaluate corn response to different sulfur (S) application rates and to determine the relationship between corn yield and plant tests. ...
Impacts of Prescribed Fire and Grazing on Northern Great Plains Rangelands
(North Dakota State University, 2018)
Prescribed burning was utilized as a management tool on grasslands of the Northern Great Plains. We analyzed the use of fire to manipulate encroaching and unpalatable western snowberry (Symphoricarpos occidentalis), to ...
Can We Increase Crop Yield Adopting Tile Drainage in Fargo Clay Soil?
(North Dakota State University, 2018)
Subsurface drainage has recently become common for agriculturally productive soils and key to maintain and improve crop production in poorly drained, frigid clay soils. The first study was conducted for four years (2014-17) ...
Geographic Distribution and Effects of Transgenic Corn Hybrids and Chemical Insecticides on Northern and Western Corn Rootworms (Coleoptera: Chrysomelidae) in North Dakota
(North Dakota State University, 2018)
Northern (Diabrotica barberi Smith & Lawrence) and western (D. virgifera virgifera LeConte) corn rootworms are major corn (Zea mays L.) pests in North America. Integrated pest management (IPM) strategies used for corn ...
Smooth Brome (Bromus Inermis) Phenology in the Northern Tallgrass Prairie
(North Dakota State University, 2018)
Smooth brome (Bromus inermis) invasion into tallgrass prairie has led to development of methods of control. Prescribed burning is used by the US Fish and Wildlife Service (USFWS) to manage prairie according to a provisional ...
Symbiotic Nitrogen Fixation in Dry Bean Cultivars
(North Dakota State University, 2018)
Dry Beans (Phaseolus vulgaris L.), is the second-most important grain legume, and North Dakota has ranked first in dry bean production. The overarching research question of my project is whether we can increase the nitrogen ...
Method Selection and Estimating Densities for Grassland Butterflies in the Mixed-Grass Prairie
(North Dakota State University, 2018)
Grassland butterflies contribute to the larger group of pollinating insects that are vital for continued plant production and food security in agroecosystems. However, grassland butterflies, along with overall biodiversity, ...
Effects of Temperature on Pea Aphids, their Host Plants, and their Parasitoids
(North Dakota State University, 2018)
Temperature has the potential to alter every aspect of an organism’s biology. This is especially true when we focus on small ectotherms such as insects. Understanding the effects of temperature on insects is particularly ...
Mid-Wisconsinan Climate Reconstruction Based on Fossil Beetles from Six Mile Creek, Ithaca, New York
(North Dakota State University, 2018)
The history of the Mid-Wisconsinan sub-stage in northeastern North America is one of large climatic oscillations. Fossil beetles were extracted from two horizons at the Six Mile Creek site, New York. A total of 738 individuals ...
Evidence of Inbreeding and Divergence in the Western Prairie Fringed Orchid (Platanthera praeclara)
(North Dakota State University, 2018)
The conversion of grasslands to agriculture land has made the tall grass prairie one of the world’s most endangered ecosystems and has played a key role in the decline of one particular species of rare endangered orchid, ...
