Plant Science
Division: Agriculture
Students completing this area of study develop a strong foundation in plant science through the study of soils, irrigation, weed management, plant diseases, pests, fertilizers, and crop cultivation. The program prepares students with practical knowledge and skills in crop production to help maximize yield, efficiency, and profitability in agricultural operations.
Students interested in careers as Pest Control Advisors (PCAs) can complete the Plant Health Certificate of Achievement, which provides the coursework needed to prepare for the California PCA licensure examination and careers in crop advising and agricultural consulting.
In Agriculture Irrigation, students earn a skill certificate in irrigation management. Students study topics such as water management and plant-water-soil relationships. The skill certificate is an ideal add-on to programs such as Agricultural Business Management and Plant Science.
