Description of course:

By the end of this 15-week course, students should understand that successful organic vegetable production relies on more than producing vegetables; it requires managing money, people, and natural resources effectively. The lessons and reading material provide an overview of cultural practices for vegetables, pest, disease, and weed control, greenhouse production and construction, irrigation practices, as well as harvesting and marketing techniques.


Three weeks are devoted to researching specifics related to growing common vegetables. At the end of the course, students reach out to farms of their choice to learn first-hand about some of the issues faced and possible solutions.


The final project is a detailed research assignment based on one of the topics reviewed during the semester (students can choose from a list of options). Although the majority of the course material is predetermined, throughout the semester students should be thinking about their personal interest within the organic vegetable field and pursue this topic during the final two weeks.


Course Structure:

At the beginning of every week students will be provided with a weekly summary list of  the work to be completed during each respective week of class. There will be a Discussion Question that students will post responses to in the “chat” section of Blackboard.  These responses are due by 11:59pm on the Sunday of that week.


Required Readings are also listed with questions that assist students to prepare for Quizzes. Four scheduled quizzes will be given during the semester.


The Final Research Project will be chosen from a list of options and culminate in an in-depth paper. Exceptions for research topics not on the list can be made with instructor’s permission.
