hi,

generally b.sc in agriculture is a 4 years undergraduate course. the eligibility criteria for b.sc in agriculture is candidates must have studied physics, chemistry and biology/agriculture as a subject in 12th course from a recognized education board. most popular entrance test for b.sc in agriculture is ICAR ug exam, where  ICAR AIEEA exam opens the entry gate for admission to 75 Agricultural Universities comprising 64 State Agricultural, Veterinary, Horticultural and Fisheries Universities (SAUs), 4 ICAR-DUs, viz. IARI, IVRI, NDRI and CIFE, 3 Central Agricultural Universities (CAU, Imphal, Dr RPCAU, Pusa and RLB CAU, Jhansi), 4 Central Universities (CUs) having Faculty of Agriculture (BHU, AMU, Viswa Bharati and Nagaland University).

In arts stream you can  not have all of the subjects of physics chemistry and biology, which makes you not eligible to apply for bsc in agriculture course.

hope you may understand.
