See both of the courses are very good and if you expect a good job in the private sector then you need to have a MSc in the field. Now if you want to go for the discipline related government job then I would recommend you to go for BSc in Agriculture. In central government as well as in state government, in both cases the job vacancies are more for Agricultural graduates as Food Inspector, Seed Corporation officer etc.
