Since you are an Agricultural Engineering student, doing PGP-FABM from IIM Ahmedabad will be a better option if you want a career in Agriculture. FABM students get recruited in Agri Inputs and Services, Agri Commodity Trading, Food, & Agri Consulting, and Agritech. Also, some recruiting companies offer common job profiles to PGP and FABM students. 

If you aren’t specifically interested in Agriculture, and want to pursue a career in HR, XLRI HRM is an excellent option. It is the best Human Resources program in the Asia-Pac region. The placement opportunities are great. 

Before choosing any of these options, check the career outcome of both the courses and see which interests you more.
