Dr. Chhetri is committed to enhancing his teaching methods by drawing on his extensive experience in research, teaching, and extension.

Course Overview

Turfgrass management definition: The creation of environmental conditions that favor the competitive nature of the desired species over all others.

This course is designed to demonstrate how certain maintenance practices can be integrated in order to provide management strategies that bring about successful turfgrass management systems. Though you have already learned about many maintenance practices, possibly as part of your job responsibilities, and/or throughout the curriculum in this Turfgrass Program, our focus in this course is to review the importance of each of these practices and understand how they work together to create effective management systems.

Course Objectives

Upon completion of TURF 425, students will have learned to:

  • accurately identify and know how to establish cool-season grasses from seed and/or vegetative methods
  • solve situational-based word problems relevant to pesticide use in the turfgrass industry
  • develop proper fertilization programs for an array of turfgrass species
  • gain an in-depth understanding of how pesticides are taken up by plants and how differing plant growth stages affect this function
  • manage different grass species in order to manipulate plant competition
  • use plant growth regulators in management programs
  • understand varying concepts contained in scientific research reports and be able to decipher meaningful information from a statistical analysis of data

Modules, Quizzes, and Exams

As a student in TURF 425, I recommend that you work through the modules in this course following the sequence and timing presented in the Syllabus and/or Calendar. However, some students may elect to work faster than others. Just remember you will be working at your own pace but must complete all of the module activities before the stated deadlines. Each week, if there is an assignment, quiz, or exam, there is a defined deadline to have it completed. All deadlines appear in the Canvas schedule.

Please be prepared to take each quiz and exam before you open it. The timer will begin as soon as you start, and it will not stop even if you log out or switch browsers. You will receive a 10-minute warning. Once the timer counts down to zero, the quiz/exam will automatically close. Quizzes and exams have varying amounts of questions and time limits; please refer to Canvas for details. 

Bonus points: There are none offered in this course.

Late Submissions

Assignments, quizzes, and exams submitted after the due date in Canvas will receive a 10% deduction per day for up to one week following the original deadline. After that window closes, you will no longer be able to submit your work. For example, if you submit a 20-point assignment one day late, you will only be able to receive a maximum of 18 points. At two days late, the maximum would reduce to 16 points.

Grading Policy

The turnaround time for graded assignments is generally one week or less.

The course's final grade is determined by the total points earned by the student. The percentages listed are for reference only.

The following table is the grading criteria for the course.

The term "Netiquette" refers to the etiquette guidelines for electronic communications, such as e-mail and discussion postings. Netiquette covers not only rules to maintain civility in discussions but also special guidelines unique to the electronic nature of messages. Please review Virginia Shea's "The Core Rules of Netiquette" for general guidelines that should be followed when communicating in this course.

Penn State Policies

Academic Integrity

Academic integrity is the pursuit of scholarly activity in an open, honest, and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle.

According to Penn State policy G-9: Academic Integrity, an academic integrity violation is "an intentional, unintentional, or attempted violation of course or assessment policies to gain an academic advantage or to advantage or disadvantage another student academically." Unless your instructor tells you otherwise, you must complete all course work entirely on your own, using only sources that have been permitted by your instructor, and you may not assist other students with papers, quizzes, exams, or other assessments. If your instructor allows you to use ideas, images, or word phrases created by another person (e.g., from Course Hero or Chegg) or by generative technology, such as ChatGPT, you must identify their source. You may not submit false or fabricated information, use the same academic work for credit in multiple courses, or share instructional content. Students with questions about academic integrity should ask their instructor before submitting work.

Students facing allegations of academic misconduct may not drop/withdraw from the affected course unless they are cleared of wrongdoing (see G-9: Academic Integrity). Attempted drops will be prevented or reversed, and students will be expected to complete course work and meet course deadlines. Students who are found responsible for academic integrity violations face academic outcomes, which can be severe, and put themselves at jeopardy for other outcomes which may include ineligibility for Dean's List, pass/fail elections, and grade forgiveness. Students may also face consequences from their home/major program and/or The Schreyer Honors College.

The University offers a variety of confidential services to help you through difficult times, including individual and group counseling, crisis intervention, consultations, online chats, and mental health screenings. These services are provided by staff who welcome all students and embrace a philosophy respectful of clients' cultural and religious backgrounds, and sensitive to differences in race, ability, gender identity, and sexual orientation.

Accommodations for Persons With Disabilities

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Student Disability Resources website provides contact information for every Penn State campus. For further information, please visit the Student Disability Resources page.

In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation. If the documentation supports your request for reasonable accommodations, your campus disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early in your courses as possible. You must follow this process for every semester that you request accommodations.

Accommodations for Military Personnel

Veterans and currently serving military personnel and/or spouses with unique circumstances (e.g., upcoming deployments, drill/duty requirements, disabilities, VA appointments, etc.) are welcome and encouraged to communicate these, in advance if possible, to the instructor in the case that special arrangements need to be made.

Use of Trade Names

Where trade names are used, no discrimination is intended and no endorsement by World Campus, Outreach and Cooperative Extension, the College of Agricultural Sciences, or The Pennsylvania State University is implied.
