Hello aspirant,

Both courses have wide scope and both options will open door to various lucrative career opportunities.If you are interested in biotechnology then go for 3 year degree UG course.It open door for scientists and researchers.
If you are interested in agriculture then go for 4 year degree course.

In today's time agriculture sector has wider scope. It open jobs to pay as well as in government sector.

But after this pandemic stress will be laid on biotechnology sector.

But scope matters less as compared to your interest.

Hope this answer is helpful for you.
