Questions

Which syllabus does this course follow?

It follows the ICAR 5th Deans' Committee syllabus of B.Sc (Hons.) Agriculture, Semester 2, used by UP agricultural universities and agriculture colleges.

What if my university syllabus is different?

The centre follows your own university's syllabus and previous papers; units missing here are added for your batch.

Does it help for competitive exams?

Yes - the same topics are asked in ICAR AIEEA PG, JRF, state agriculture officer and banking AFO exams.
