Herbicide Screening in Industrial Hemp (Cannabis sativa L.) Production
(North Dakota State University, 2021)Lack of labeled herbicides for industrial hemp (Cannabis sativa L.) production in the U.S. accentuates urgency to identify herbicides for weed control. Weed competition reduced seed yield by 25 to 32%. Pre- and post-emergence ... -
Productive and Economic Analysis of Silage Maize and Alfalfa Intercropping
(North Dakota State University, 2021)Intercropping of maize (Zea mays L.) and alfalfa (Medicago sativa L.) is not a commonpractice because alfalfa generally reduces maize grain and biomass yield. The objective of thisresearch was to evaluate the productivity ... -
Nitrogen and Spacing Requirments for Advanced Chipping Selections ND7799C-1 and ND7519-1
(North Dakota State University, 2021)To understand the best agronomic practices, including nitrogen fertilization rate and within-row spacing for two potential cultivar releases of NDSU, a study was carried out in 2018 and 2019 for the advanced chipping ... -
Potassium Fertilization and Its Impact on Yield, Nutritive Value, Root Reserves, and Winter Hardiness of Alfalfa
(North Dakota State University, 2021)Potassium (K) is an important nutrient for winter hardiness in alfalfa (Medicago sativa L.). This study determined the effect of K rate and application timing, fall dormancy, and harvest stress on forage yield, nutritive ... -
Mapping the Ur-5 Gene Conferring Resistance to Common Bean Rust
(North Dakota State University, 2021)Bean rust (Uromyces appendiculatus (Pers) Unger), is a highly virulent pathogen that negatively affects bean (Phaseolus vulgaris L.) seed yield. Over time, bean rust has the capacity to generate new races that overcome the ... -
Season Extension Using Supplemental Soil Heat in a North Dakota High Tunnel for Warm Season Vegetable Production
(North Dakota State University, 2021)Vegetable production options in North Dakota are limited by environmental challenges. Combining soil heating cables and row covers within a high tunnel could protect crops from frost, extending the growing season. Three ... -
Nitrogen Uptake Effects on Potato Yield and Quality
(North Dakota State University, 2021)Nitrogen (N) is one of the vital elements for potato production. As well as common synthetic fertilizers, turkey manure compost (TMC) is more commonly used as a source of N for potato production in Minnesota. The aim of ... -
Influence of High Surfactant Oil Concentrate Adjuvants and Oil Rate Response to Spray Volume on Herbicide Efficacy
(North Dakota State University, 2021)There is limited research on High Surfactant Oil Concentrates (HSOC), so studies were conducted for their evaluation. Multiple MSO-based (HSMOC) and POC-based (HSPOC) HSOCs were tested with glyphosate plus dicamba or ... -
Stone Milling of Hard Red Spring Wheat: Effect of Settings on Flour, Dough and Bread Quality
(North Dakota State University, 2020)Stone milling is an ancient method for grinding without separation of the wheat constituents to produce flour. This study evaluated the effect of three different stone gaps (setting wide, medium, and narrow) and 200 and ... -
Transfer of FHB Resistance Genes into Hard Red Winter Wheat
(North Dakota State University, 2020)Fusarium head blight (FHB) is a serious foliar disease of hard red winter wheat (HRWW) in North Dakota. Disease resistance was identified as major component in disease management. First objective of this study is to transfer ... -
Pre-Breeding to Improve Yield and Disease Resistance of Hard Red Winter Wheat
(North Dakota State University, 2020)Challenges to growing winter wheat in North Dakota include winter temperature and disease pressure. Fusarium head blight (FHB) is a devastating disease that necessitates breeding for resistance. In the NDSU breeding program ... -
Management Strategies for the Cultivation of Hop, a Specialty Crop for North Dakota
(North Dakota State University, 2020)Field experiments were conducted in 2017 and 2018 at the NDSU Horticulture Research Farm near Absaraka, ND to evaluate the growth and yield characteristics of twelve commercial hop cultivars in response to varied training ... -
Nitrogen Sources and Their Management on Wheat Yield and Protein
(North Dakota State University, 2020)Nitrogen (N) fertilizer management in wheat (Triticum aestivum L.) can impact grain yield and protein. Develping strategies that improve N efficiency are needed to optimize wheat production in North Dakota. Field experiments ... -
Comparative Study on Hulled Wheats Kernel, Flour, Dough Quality and Dietary Fiber Variation
(North Dakota State University, 2020)This study was conducted to evaluate the kernel, flour and dough qualities and dietary fiber content of hulled wheats. Experimental design was separate randomized complete block designs for hulled wheat species with four ... -
Multi-Parent Advanced Generation Inter-Cross Population for Improvement of Genetic Resistance of Dry Bean to White Mold
(North Dakota State University, 2020)White mold (Sclerotinia sclerotiorum Lib. de Bary) is one of the most important diseases of common bean in the U.S. with seed yield losses up to 100%. White mold resistance is hard to incorporate into breeding materials ... -
Seeding Date and Genotype Maturity Interactions on Grain Sorghum [Sorghum bicolor –(L.) Moench] Performance In North Dakota
(North Dakota State University, 2020)Grain sorghum [Sorghum bicolor (L.) Moench] varieties fail to reach maturity in North Dakota’s short and cool growing season. The study objective was to evaluate seeding date and white grain sorghum genotypes. A randomized ... -
Genetic Dissection of Tan Spot Resistance in Wheat
(North Dakota State University, 2020)Tan spot, caused by the necrotrophic fungal pathogen Pyrenophora tritici-repentis (Ptr), is a major foliar disease in wheat. QTL mapping and meta-QTL analysis are effective methods to understand genetic basis of tan spot ... -
Comparison of Two Single Curtain and Two Double Curtain Trellis Systems with Marquette and Petite Pearl Wine Grapes
