If you’re aiming for Plant Science in 2026, this is one of those courses where your subject combination really matters. Not in a scary way—but in a “don’t play yourself at registration” way.
Plant Science sits comfortably in the science/agriculture space, and Joint Admissions and Matriculation Board expects candidates to show a solid science background. Before we list the subjects (we’ll get there, don’t rush), let’s break down why certain subjects are required and where the flexibility comes in.
What Plant Science Is Really About (Quick Reality Check)
Plant Science isn’t just “learning about plants.” At university level, you’ll deal with:
-
plant growth and development
-
genetics and breeding
-
soil–plant relationships
-
crop production and protection
-
plant physiology and biochemistry
So JAMB is basically checking: Does this candidate have the science foundation to survive this course?
That’s why some subjects are non-negotiable, while others are choose-one options.
The Non-Negotiables: Core Subjects for Plant Science
No matter the university, these subjects form the backbone of Plant Science in JAMB 2026.
Core subjects (must be included):
-
Use of English – compulsory for every course
-
Biology – this is the heart of Plant Science
Biology is not optional here. If Biology is missing, admission officers won’t even blink before moving on.
Where the Flexibility Comes In (This Is the Part People Miss)
Plant Science is interdisciplinary. It connects biology with chemistry, physics, and sometimes agriculture-related logic. Because of that, JAMB allows options for the remaining subjects.
This means:
-
You don’t need all science subjects
-
You must choose the right mix that aligns with your strengths
Approved JAMB Subject Combination for Plant Science (2026)
After the two core subjects, you are required to add two more subjects from an approved pool.
Correct JAMB subject combination:
-
Use of English
-
Biology
-
Chemistry
-
Any one of the following:
-
Physics
-
Mathematics
-
Agricultural Science
-
That gives you your four subjects.
Why These Optional Subjects Are Accepted
-
Chemistry: Essential for understanding plant nutrition, metabolism, and soil chemistry. Most universities treat Chemistry as a strong requirement, not just an option.
-
Physics: Helps with environmental interactions, energy transfer, and instrumentation used in labs.
-
Mathematics: Useful for data analysis, genetics calculations, and research methods.
-
Agricultural Science: Very relevant, especially for universities that run Plant Science under Agriculture or Crop Science faculties.
Different schools may prefer one over another, but JAMB allows you to choose one based on what you’re strongest in.
Common Mistakes Plant Science Candidates Make
Let’s save you from unnecessary heartbreak:
-
Replacing Biology with Agricultural Science (this is wrong)
-
Choosing Chemistry as an optional add-on instead of a main science subject
-
Assuming all universities accept the same combination without checking
Always remember: Biology is compulsory. Chemistry is strongly expected. The fourth subject is where you choose wisely.
Final Tip Before You Register
Some universities list Plant Science as:
-
Plant Science and Biotechnology
-
Crop Science
-
Plant Biology
The subject combination is usually the same, but it’s smart to cross-check the university’s requirements before locking in your JAMB form.
Summary (Quick Recap)
JAMB Subject Combination for Plant Science in 2026
-
Use of English (compulsory)
-
Biology (compulsory)
-
Chemistry
-
Physics or Mathematics or Agricultural Science
Choose based on your strength, not vibes.
