  • Irrigation Home Study Course
    Chuck Burr Extension Educator Univ of Nebraska chuck.burr@unl.edu
    The intent of this Home Study Course is to increase the user’s awareness and understanding of irrigation management concepts. This in turn can help producers reduce irrigation application amounts and increase uniformity of application, thereby reducing deep percolation and runoff. The end result can be reduced irrigation costs, increased efficiency, increased yields and reduced surface and groundwater contamination. The target audience for this course includes: crop consultants, agency personnel, irrigated crop producers and others interested in improving their irrigation water management skills. There is additional information on irrigation management on the UNL Water webpage: http://water.unl.edu/web/cropswater/home It is hoped that you find this course both helpful and enjoyable. To begin work in the course click on "Lessons" in the task bar above.  This will take you to a page where you can click on links to view each chapter.  We recommend that you print a few of the addenda, especially the Tables and the Equations.  For best printing results, set the printing properties to Portrait and, if available, to print both sides.  Upon completing a chapter you can take the quiz by clicking on the "Quiz" link included in each lesson; you may use your printed addenda while taking each quiz.  To earn CEU credit, you'll need to get 8 of 10 questions correct.  You may retake quizzes as many times as you wish.

    Welcome to the Plant Breeding Training Network (PBTN)!  Feel free to browse the reference materials located within the community.  If you would like to view current discussion topics and collaborate with other community members, you'll need to create an account Here are instructions about how to create a PBTN account. If you are visiting the community page to attend a webinar, here are instructions on how to use the Adobe Connect meeting room. Please click the Adobe Connect icon above. Enter as a guest with your name and institution.  Building on infrastructure created through the support of NSF, The Plant Breeding Training Network has been created as part of the Triticeae CAP funded through USDA NIFA. PBTN launched the summer of 2011. As it grows and develops, we anticipate breeding and genetics collaborators from other plant species will be added. Please take a look around and we hope you find the materials, webinars, classes and interactions with colleagues in this environment to be rewarding. Together we can meet the food needs of a growing population, in the midst of climate challenges. We hope you become a frequent visitor of this site to share with us the experiences of this exciting project. Deana Namuth-Covert and Jason Cook PBTN Directors Gary Muhelbauer and Jorge Dubcovsky TCAP Project Directors

Featured Lessons
  • Herbicides That Act Through Photosynthesis This lesson will examine herbicides that adversely affect light-related processes, thereby causing damage to plants. There are four basic mechanisms that will be studied in this class of agents: herbicides that inhibit or block synthesis of Protoporphyrin IX; herbicides that inhibit synthesis of carotenoids; herbicides that block Photosystem II electron transfer; and herbicides that divert electrons from Photosystem I. All share the ability to cause cellular damage in the presence of light.
