hi,

see agriculture engineers generally work on the technical parts of work related with agriculture companies, manufacturing works, mills where different food products manufacturers.  may work as a business analyst in agriculture business farms etc. see in india there is less opportunity for agriculture engineers to work in core department, so thats why you may do m.tech on pollution control or environment science related stream which has better opportunity. also mba in agribusiness management is also a good options to pursue higher studies.
