Hello, 

You are eligible for BSc Agriculture Science in majority of universities, since there are two steams  whose student can opt for  bsc agriculture : pcm, pcb as because both biology and maths are required in agriculture. 

And also for pcm students biology is made a compulsory subject   and for pcb students maths is made a compulsory subject during initial years of your bsc agriculture course.

Hope this helped

Good luck
