Fungicide Resistance: Surveillance, Risk Assessment And Evolution In Two Soil-Borne Pathogens, Nikita Gambhir
Fungicide Resistance: Surveillance, Risk Assessment And Evolution In Two Soil-Borne Pathogens, Nikita Gambhir
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Fungicide-resistant pathogens are an increasing threat to fungicide efficacy and plant health. The goal of this dissertation was to advance the foundational knowledge required to prevent and detect fungicide resistance development in the seedling disease pathogen, Rhizoctonia zeae and the white-mold pathogen, Sclerotinia sclerotiorum. Corn and soybean fields in 12 states (IA, IL, IN, KS, KY, MI, MN, MO, ND, NE, SD, and WI) were surveyed for R. zeae. In vitro fungicide sensitivity was determined for 91 isolates to fludioxonil, sedaxane, and/or prothioconazole. Rhizoctonia zeae was sensitive to all fungicides (EC50 < 3 µg/ml) except azoxystrobin (EC50 > 100 µg/ml). In planta application of …
Effects Of Different Water And Nitrogen Regimens On Yield Of Winter Wheat Produced In Nebraska, Joseph Emory Davis
Effects Of Different Water And Nitrogen Regimens On Yield Of Winter Wheat Produced In Nebraska, Joseph Emory Davis
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Wheat is the 3rd most prominent crop in the USA and approximately 50% is exported annually. Nebraska wheat production is 11th in the country, and it plays a major role in the state's agricultural economy, especially in western NE. Generally, wheat is grown under dryland conditions and the region grows much more wheat on unirrigated land than it does on irrigated. However, deficit irrigation has shown great value in producing high yielding wheat with much less water than needed for other crops. Finding new ways to leverage irrigation in wheat production may help address the need to produce food …
Forage Quality Evaluations Of Twelve Grasses In Relation To Season For Grazing, L. C. Newell, W. J. Moline
Forage Quality Evaluations Of Twelve Grasses In Relation To Season For Grazing, L. C. Newell, W. J. Moline
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A study of forage quality in relation to seasonal yield of important perennial forage grasses was initiated to provide information and to promote a better understanding of their best use for grazing. This information should be particularly valuable in planning seasonal use of pure stands or mixtures of grasses.
A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff
A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This study was undertaken to inventory the soils and vegetation of certain areas of the Sandhills and to seek edaphic characteristics that may be the limiting factor in the distribution of various plant species. Information of this nature will permit formulation of more accurate management practices because of a refinement in delineation of range sites.
Effect Of Storage Temperatures On Triumph Seed Potatoes Used For The Early Crop In The South And In Central Nebraska, H. O. Werner
Effect Of Storage Temperatures On Triumph Seed Potatoes Used For The Early Crop In The South And In Central Nebraska, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
During the decade 1931-1940 it became increasingly apparent that some factor (or factors) besides disease was responsible for much of the variation in yields produced by lots of certified seed potatoes planted in commercial fields and comparative trial plots in the South during midwinter. This bulletin reports investigations into the method of storing western Nebraska seed potatoes as a means of improving the production of the early crop of Triumphs in the Gulf Coast States.
The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim
The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The purpose of this investigation was to determine some of the factors involved in the regional adaptation of corn. The procedure has been to make a comparative study of native corn types, known to be locally adapted to various regional areas in Nebraska through long growth there. The work has been confined to the single species group - Zea mays indentata. No one variety of a common source is grown throughout the state, and therefore it has been impossible to keep within a single variety. It would appear that the data should indicate morphological and histological plant characteristics involved …
