Course Description: Physiological processes in crop growth, development, and yield: photosynthesis, respiration, water relations, mineral nutrition, assimilate partitioning, seedling vigor, light interception and canopy growth, root growth, reproduction, and yield. Required course for the Master of Science in Agronomy degree program and Agronomy Graduate Certificate program.
Course Prerequisites: AGRON 181 or equivalent, MATH 140, CHEM 163, BIOL 101. Restricted to graduate students enrolled in MS Agronomy, Agronomy Graduate Certificate, and MS Plant Breeding online degree programs at ISU. Students from other departments must get permission.
Expected Learning Outcomes
Agronomy 501 is one of three foundation courses in the Master of Science in Agronomy program. Subsequent courses build on and apply the material presented in these foundational courses. Thus, it is essential you develop a solid understanding of the concepts and information covered. Crops beyond corn and soybean will be used particularly in the first half of the course when we are working on universal physiological principles. Corn and soybean will be used predominately in the second half of the course.
Based on information learned from this course, you will:
- Understand the relationship between crop physiology, growth, developmental processes, and yield;
- Understand the role of environment (climatic and soil) in providing necessary inputs for crop growth; and
- Be able to explain the science underlying many crop production practices.
With a thorough understanding of the basic principles of crop physiology, you will be better prepared to:
- Evaluate crop needs and the suitability of various practices to satisfy those needs,
- Troubleshoot effectively, and
- Design and implement appropriate solutions and practices that optimize crop productivity.
As you study each module, reflect on how the information you are learning explains or applies to what you have observed or experienced in various cropping situations, and how those cropping systems might be improved.
Your ability to use a web browser, input assessment responses via text-editing software such as Microsoft Word, and access all of the technologies will directly influence your success in the course. If you have not already done so:
- Visit the MS Agronomy website and look for the section titled "Browser and Computer Compatibility Test: Your Results". Ensure your computer passes all areas of the test. This will ensure your ability to fully utilize the online course materials.
- Then, visit the MyCanvas Student guide developed by Iowa State University. Complete the first module, called “Getting Started in Canvas”, to learn about Canvas’s technical requirements and which browser you should use for Canvas.
Online Course Materials Format
The online course materials in Agronomy 501 consist of 14 modules. Your activities include:
- Reading the online module material and utilizing the included learning tools.
- Responding thoughtfully to each Group Discussion Topic. The Discussion Topics are designed to help you gain perspective on how the concepts in the module might be applied in various situations.
- Completing Individual Assignments particular to your area and crop choice.
- Completing each Module Exam. The exams occur on a weekly basis and take the place of midterm and final exams.
There is no required textbook for this course. All instructional materials will be provided via Canvas.
Some students have asked for a reference textbook especially if they did not have plant science coursework in their undergraduate program. I recommend this textbook:
- There also is a free download of the Third Edition available (scroll down to Download Options).
- Fundamentals of Plant Physiology is a new textbook that is a simplified version of the sixth edition textbook. I have not used this book but it is likely a good resource.
It is important to have a good understanding of crop growth and development stages and general progression for corn, soybean, and wheat. This content is similar to what you would learn in a 1- or 2-day crop scouting class. I highly recommend purchasing these as they will be helpful throughout your career:
Your course grade will be composed of the following categories. Points earned on each discussion and exam will be posted in the Grades section of Canvas.
|Modules||Points Per Module||Total Points|
|Group Discussion Topics||11||10||110|
Your grade will be calculated as the number of points earned out of 670 total points, as shown in the Table. I will not scale at the end of the semester.
Be aware the ISU Graduate College requires you to maintain a cumulative grade point average (GPA) of at least 3.0 (B) on all course work taken, exclusive of creative component credits. For more specific information, please refer to the ISU Graduate Student Handbook.
|Total Points Earned||Percent||Letter Grade|
|616 or more||92||A|
Discussion Topics are designed to explore or apply a module concept and contribute to the development of your professional communication skills. Points are earned through your lead post and active participation in the discussion group.
The class will be divided into several groups each week; you will be assigned to one of at random. Discussion contributions will be evaluated on these criteria:
|Criteria||Grading Criteria||Possible Points|
|Timely posting||Lead post is made by Sunday midnight (12 am CT).||1|
|Lead post on the topic||Respond to the discussion topic with an in-depth post supported by literature and/or personal experience. Cite all sources of published information used.||5|
|Respond to classmate's lead postings||Respond to 3 lead posts with thoughtful questions, aspects to consider, or a differing viewpoint. Ensure your post promotes critical thinking and further discussion (1 pt each).||3|
|Respond to questions about your lead post||Respond to questions posed by your classmates on your lead post.||1|
Exam (35 points each). An exam occurs at the end of each Module and comprised of true-false, multiple choice, and open text (couple paragraphs typically). You have two hours to complete each exam. Questions are designed to evaluate your understanding of the physiological concepts presented in the module and their application to 'real world' agronomic and crop production issues. Access to the current and previous modules is permitted while answering these questions. Answers that address the question directly, are logically developed without plagiarizing the module text, and are physiologically accurate will be graded favorably. Grades for all 14 Exams will be pooled to calculate your 'Exam Grade' for the course. I will provide feedback on each exam particularly in areas that points were deducted.
Practice and polish your professionalism. Professionalism includes respectful and courteous interactions with classmates and instructor, your active participation in discussions, clear and logical expression of ideas and thought, and completion of the course evaluation. Because quality is an important part of your professional development, apply good writing skills on all of your discussions. Need a refresher on grammar or other writing mechanics? Check out the ISU online Writing Help Center. Cite your sources! Plagiarizing published information is unethical and will be reported to the Dean of Students.
All communication within the course should adhere to university standards of Netiquette at ISU. Specifically, communication should be scholarly, respectful, professional, and polite. You are encouraged to disagree with other students, but such disagreements need to be based upon facts and documentation. It is the instructor’s goal to promote an atmosphere of mutual respect in our interactions. Please contact the instructor if you have suggestions for improving the interactions in this course.
Use the General Discussion forum in Canvas (or e-mail) to ask questions, share an interesting article or observation, or comment on current and relevant events. Keep informed—check the discussion board frequently.
General announcements will be posted to the Announcements section of Canvas.
Be sure to properly configure your Notification settings or commit yourself to check Canvas daily for new communication.
Additional guidelines apply to communication within your discussion groups. Please review the Discussion Topic rubric shown above.

Get the most that you can from this course. Here are some study tips.
- Start each module on the date indicated on the calendar. Complete one module each week. Allow about 6 to 7 hours per module (approximately 3 or 4 hours is needed to do the module, plus 1 to 2 hours to participate in discussions). To better understand and retain the information, spread your study time over several days. Work ahead when you know that you will be out-of-town or unable to do a module during its designated period.
- Do each In Detail as you come across its link in the module. In Detail items contain required information.
- Do each Study Question and Try This! as encountered. These interactive features are specifically designed to enhance your learning, to provide opportunities to apply the information presented, and to let you evaluate your understanding of the material. They often expand on the concepts—don't skip these.
- Discussion Topics. The discussion forum is an opportunity to interact with your classmates on practical issues related to the weekly module. The topics are an integral part of the course. Your individual 'lead post' and responses to other members of the group are required for full credit.
- Module Exam. Each module is designed to test your knowledge and ability to apply one or more of the concepts from the module to a practical problem or issue. A concise, well-conceived, and logically presented answer will be graded more favorably than one that wanders aimlessly. Read the questions carefully and consider what they are asking. Post your answer by the due date to receive full credit. It is most important that the answer is your original work.
- Interact with your classmates and instructor. Visit the discussion boards often! Discussions need not be limited to assigned topics—use the discussion board to ask questions, share an interesting article or observation, or comment on current and relevant events. If you work ahead, be sure to go back and check the discussion boards (and post your comments and responses to classmates) during that module's scheduled period.
- Something unclear? Please consult with me and your classmates. Questions are welcome anytime.
