    Greenhouse experiments were conducted to determine the response of Brassica oleracea L., pac choi to fertilizer rates and sources and to establish optimal soluble nitrogen (N) application rates and nitrate meter sufficiency ...
  • Boyer, Cheryl R.; Torbert, H. Allen; Gilliam, Charles H.; Fain, Glenn B.; Gallagher, Thomas V.; Sibley, Jeff L. (2013-05-21)
    Rising costs of potting substrates have caused horticultural growers to search for alternative, lower-costmaterials. Objectives of this study were to determine the extent of nitrogen immobilization and microbial respiration ...
  • Bremer, Dale J. (2009-03-02)
    Urban ecosystems are rapidly expanding and their effects on atmospheric nitrous oxide (N[subscript]2O) inventories are unknown. Our objectives were to: 1) measure the magnitude, seasonal patterns, and annual emissions of ...

    Several species of bumble bees are declining in the United States; these declining populations often show higher prevalence of Nosema bombi, a microsporidian pathogen. To date, surveys of bumble bee pathogens in the United ...
  • Forbes, W.L.; Corah, L.R.; Thompson, K. E.; Lamb, G.C.; Grieger, David M.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)
    We used four herds at three Kansas ranches to evaluate the potential of two new estrus synchronization strategies to increase estrus expression and fertility of 911 crossbred suckled beef cows. The treatments included: 1) ...
  • Ahnström, M.L.; Seyfert, M.; Hunt, Melvin C.; Johnson, D.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-08-02)
    The traditional dry-aging method for beef was compared with a novel technique of dry aging in a highly moisture-permeable vacuum bag. Paired beef strip loins were cut into four sections and were dry aged traditionally ...
  • Fabrick, Jeff; Oppert, Chris; Lorenzen, Marce D.; Morris, Kaley; Oppert, Brenda; Jurat-Fuentes, Juan Luis (2009-11-20)
    Cry toxins produced by the bacterium Bacillus thuringiensis (Bt) are effective biological insecticides. Cadherin-like proteins have been reported as functional Cry1A toxin receptors in Lepidoptera. Here we present data ...

    Background: Triticum monococcum (2n) is a close ancestor of T. urartu, the A-genome progenitor of cultivated hexaploid wheat, and is therefore a useful model for the study of components regulating photomorphogenesis in ...
  • Bockus, William W.; Su, Zhaohui; Garrett, Karen A.; Gill, Bikram S.; Stack, James P.; Fritz, Allan K.; Roozeboom, Kraig L.; Martin, T. Joe (2012-05-31)

    Groups of 6, 12, or 24 pigs averaging 37 pounds each were assigned to pens where each pig had 3.85 square feet of floor space for a 4-week feeding period. Pigs in groups of 12 gained significantly slower and showed a much ...
  • Rantanen, M.M.; Hines, Robert H.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-26)
    A total of 100 weanling pigs with an average initial body wt of 11.8 lb and average age of 17 d was used in a 38-d growth assay to determine the effect of castration on growth performance of nursery pigs. All pigs were ...
