Undergraduate Study

Agronomy is the science and technology of producing plants that serve humans, using practices essential for maintaining and improving life. The Department of Agronomy offers a major leading to a degree of Bachelor of Science (B.S.) in agronomy. Graduates have the theoretical and practical knowledge needed for efficient and sustainable crop production. They are skilled in critical thinking, problem solving, communicating, and working effectively with others. They understand the ethical, cultural, and environmental dimensions of issues facing agronomists globally.

An agronomy major prepares students for employment in crop production and soil management, yield forecasting, precision farming, plant breeding, agricultural business and industry, agricultural service organizations, environmental and natural resource management, and farm management. Graduates pursue careers in the seed, fertilizer, and agricultural chemical industries as field agronomists, crop and soil management specialists, research technicians, sales and marketing specialists, and production managers. State and federal agencies employ agronomists as extension specialists, county extension directors, environmental and natural resource specialists, research associates, soil surveyors, soil conservationists, grain inspectors, integrated pest managers, land appraisers, agricultural lenders, and other science-based professionals.

An agronomy major also prepares students for graduate school. We offer a concurrent B.S./MBA degree. About a quarter of our students immediately continue into research-based M.S. and Ph.D. programs. As an undergraduate, there are many opportunities to be involved in research.

Graduate Study

Introduction

Agronomy is the science and technology of producing plants that serve humans, using practices essential for maintaining and improving life. The Department of Agronomy administers Master of Science (M.S.) and Doctor of Philosophy (Ph.D.) degree programs in four different graduate majors that emphasize different disciplines of agronomy. These majors are: Agricultural Meteorology; Crop Production and Physiology; Plant Breeding; and Soil Science. A fifth graduate major, Agronomy, offers both an M.S. and a Graduate Certificate through distance education suitable for professionals working in industry or government, as well as a graduate minor for on–campus students.


Admission

To be fully admitted, prospective graduate students must have an undergraduate GPA of at least a 3.00 GPA (4.00 scale) or rank in the upper one–half of their undergraduate class. Non–native English speakers must take the Test of English as a Foreign Language (TOEFL). Students applying to the Agricultural Meteorology and Plant Breeding graduate majors must take the Graduate Record Examination (GRE). For all of the majors except Agronomy, a faculty member of the graduate major must agree to be the major professor before the student is admitted.


Program of Study

The academic courses used to satisfy requirements for a graduate degree compose a student’s Program of Study (POS). The POS must be approved by the student’s POS Committee. For the M.S. in Agronomy, the POS Committee must be composed of at least two faculty who are both members of the Graduate Major in Agronomy. For the other four majors at the M.S. degree level, at least three faculty must serve on a POS Committee. Two of the three must be members of the major, and at least one must be a member of a different graduate major. At the Ph.D. level the POS Committee must have at least five members, of which at least three must be faculty in the major, and at least one a member of a different graduate major. If the student is pursuing a graduate minor, either as part of an M.S. or Ph.D., a graduate faculty member representing the minor must serve on the POS Committee.

Agronomy

The POS for the M.S. in Agronomy is fixed and consists of the following:

AGRON 5010Crop Growth and Development3
AGRON 5020Chemistry, Physics, and Biology of Soils3
AGRON 5030Climate and Crop Growth3
AGRON 5110Crop Improvement3
AGRON 5120Soil-Plant Environment3
AGRON 5130Data Science for Agricultural Professionals3
AGRON 5140Integrated Pest Management3
AGRON 5310Crop Ecology and Management3

Core Area 5 (statistics / quantitative methods): AGRON 5250, AGRON 5260, STAT 5870, STAT 5050, STAT 5120, STAT 5880, CRP 5510, and NREM 5460.

To major in Crop Production and Physiology, at least one course from three of the Core Areas must be included in the POS for the M.S. For the Ph.D., at least one course from each of the Core Areas must be included. A single course cannot be used for more than one Core Area. Students are also encouraged to consider AGRON 6980.

Plant Breeding

The Graduate Major in Plant Breeding has both a resident and distance–education MS program.  The following courses are recommended for students with a major in Plant Breeding: AGRON 5210AGRON 5220, AGRON 5230, AGRON 5240, AGRON 5280, AGRON 5610, AGRON 6000A, AGRON 6980STAT 5870, and STAT 4710. For the distance program, the following courses are recommended: AGRON 5010, AGRON 5060, AGRON 5130, AGRON 5200, AGRON 5210, AGRON 5230AGRON 5240, AGRON 5280, AGRON 5440, and AGRON 5990. Resident students pursuing the Ph.D. also often include AGRON 6210 and AGRON 6250 in their POS.

Soil Science

Students pursuing a major in Soil Science may specialize in one of six areas: soil chemistry; soil fertility; soil management; soil microbiology and biochemistry; soil morphology and genesis; or soil physics. If a specialization is chosen, the major professor must be in the designated specialty area. For the Ph.D., the POS must include one credit of AGRON 6000B. Students are also encouraged to consider including AGRON 6980 in their POS. 

Master of Science

The general requirements for an M.S. degree include: 

  • A minimum of 30 credits from academic courses and research activities;
  • At least 22 credits earned at ISU;
  • Two–thirds or more of earned credits related to the major; and
  • Completion of a final oral examination.

Both non–thesis and thesis options for an M.S. degree in Agricultural Meteorology, Crop Production and Physiology, Plant Breeding, and Soil Science are available. Students in the Agronomy major must choose the non–thesis option.

Students in Agricultural Meteorology working towards the M.S. must meet with their POS Committee at least twice. Besides the final oral examination, an additional meeting must be held near the beginning of the graduate program. At this meeting the student will introduce the area of research to be pursued, potential research questions and methods, and a proposed POS. The student must also present a short written report on how the proposed research will help them master established Enduring Understandings in Agricultural Meteorology.

Creative Component

If the non–thesis MS degree is chosen, then the student must:
1. Register for at least two credits of AGRON 5990 that will be used to complete a creative component; and
2. Pass a comprehensive final oral examination.
The creative component is work that presents substantial evidence of individual accomplishment. The POS Committee and the student will specify the creative component, how it will be documented, and how it will be evaluated. The POS Committee also has flexibility in determining the format of the final oral examination. For Agricultural Meteorology, the final oral exam must include an evaluation of the student’s mastery of the Enduring Understandings in Agricultural Meteorology.

Thesis

In the thesis option the student must:
1. Pursue a research project culminating in a written thesis; and
2. Pass a comprehensive final oral examination.

A minimum of three research credits of AGRON 6990 must be listed on the POS to account for work on an M.S. thesis. The thesis is submitted to the POS Committee prior to the final oral examination.  During the final oral examination, the student will present and defend the thesis in the presence of the POS Committee. Students in Agricultural Meteorology must also demonstrate mastery of the Enduring Understandings in Agricultural Meteorology. The presentation (also called the “exit seminar”) is open to the general public. Only POS Committee members may attend the examination that follows the presentation.

Doctor of Philosophy

The general requirements for a Ph.D. degree include:

  • A minimum of 72 credits from academic courses and research activities.
  • At least 36 of these credits earned at ISU
  • Completion of a preliminary oral examination;
  • A written Ph.D. dissertation; and
  • Completion of a comprehensive final oral examination.

The 72 credits can include the credits earned in pursuit of an M.S. degree. If an M.S. was earned at another institution, those courses earned at the other institution can be listed along with the ISU courses, but only if the POS Committee determines that the courses are appropriate. Students in Agricultural Meteorology working towards the Ph.D. must meet with their POS Committee at least three times. Besides the final oral examination and another for the preliminary exam, an additional meeting must be held near the beginning of the graduate program. At this meeting the student will introduce the area of research to be pursued, potential research questions and methods, and a proposed POS. If a student will pursue a Ph.D. without first completing an M.S., then during the first meeting of the POS Committee the student must also present a short-written report that illustrates connections between the Enduring Understandings in Agricultural Meteorology and their planned research.

Qualification Exam

Agricultural Meteorology
Students in Agricultural Meteorology must take and pass a qualification exam once they have decided to pursue a Ph.D. The qualification exam must be passed before taking the preliminary exam. The format of the qualification exam is as follows. The student will produce a written report that demonstrates their knowledge of the Enduring Understandings in Agricultural Meteorology. If the student has come from another university the report must present research completed at ISU and not at the previous institution (such as a thesis). This report will be submitted to all of the faculty in the major. The student will then make an oral presentation to faculty and other students in the major that summarizes and defends the written report. After the oral presentation, the faculty will meet to determine whether or not the student passed the exam, and whether the student can re–take the exam if the student failed. The faculty will provide written feedback to the student, suggesting areas where improvement is needed and a course of action. The qualification exam can be taken only two times during a student’s graduate career at ISU. If a student who had entered the Ph.D. program without an M.S. degree takes the qualification exam and fails the exam, the student can: take the qualification exam again, if so, allowed by the faculty; or continue their graduate career in pursuit of an M.S. degree. In the latter case, the student could take the qualification exam one more time after an M.S. degree has been completed.

All Other Majors
A qualification exam is not required for students in the Crop Production and Physiology, Plant Breeding, or Soil Science majors.

Preliminary Exam

All students pursuing a Ph.D. must take and pass a preliminary oral examination.

Agricultural Meteorology
For students in Agricultural Meteorology the preliminary exam consists of a defense of the student’s proposed dissertation research to the POS Committee. Besides an oral defense, the student must also submit a written report on their proposed research. If the student fails the preliminary exam, the POS Committee must also decide if the student can re–take the exam. The preliminary exam can only be taken twice.  

Crop Production and Physiology
Students in Crop Production and Physiology may be asked to take a written preliminary examination. If a student fails the written preliminary examination, the POS Committee may require the student to retake the exam, to answer additional written questions, or proceed with the oral examination. The nature of the preliminary oral exam is determined by the student’s POS Committee.

Plant Breeding
Students in Plant Breeding must pass a uniform written preliminary examination that consists of five questions, each from one of five topical areas. Faculty members in Plant Breeding evaluate each answer. Evaluators assign a pass or fail grade to the answer. If an evaluator assigns a failing grade to a question, the evaluator shall clearly indicate the strengths and weaknesses of the answer and provide written information (e.g., references, rationale) to the student which clearly outlines an acceptable response to the question. Failure to provide such written information may invalidate that grade and be considered sufficient cause to exclude the grade in the overall evaluation of the student’s answer. Students who receive two pass grades for a question will have successfully completed that topic, and students must pass each topic to pass the exam. If two valid grades are not in agreement (e.g., one passing grade and one failing grade), additional faculty members will evaluate the answer until there are two valid assessments that are in agreement. Students who do not pass a topic have the opportunity to repeat that topic on the next regularly scheduled exam date. The number of attempts for each topic has not been specified. The examination is offered the last Thursday and Friday of each January and September when one or more students have signed up to take the exam. Students may choose to attempt questions for all five topics, or for subsets of the topics. If a student decides to attempt questions for only certain topics, the student must specify which topics in writing at least one month prior to the scheduled exam date. The nature of the preliminary oral exam is determined by the student’s POS Committee.

Soil Science
Students in Soil Science must pass a written preliminary examination. Exam questions are authored by members of the POS Committee. The format of each question is left open and they may be formulated as open– or closed–book problems. A reasonable period for completion may be set by the author of the question. The student’s responses are formally scored or ranked only by the POS Committee member who authored the question. A copy of the student’s responses to all questions is submitted to all POS Committee members at least one week before the student’s preliminary oral examination. When the student submits a request to schedule the preliminary oral examination, the student’s major professor certifies by signing the form that the student has satisfactorily completed a written preliminary exam. The nature of the preliminary oral exam is determined by the student’s POS Committee.  

Doctoral Dissertation and Final Oral Examination

All students must include at least three AGRON 6990 credits in their POS for work on their Ph.D. dissertation. During the required final oral examination, a student presents and defends the dissertation. This presentation (also called the “exit seminar”) is open to the general public. Only POS Committee members may attend the examination that follows the presentation.
