SHUATS is better than Integral university if we talk about MBA Agribusiness specifically as SHUATS is entirely about agriculture and technology and you will get more experienced  faculty who belong to the agriculture field whereas Integral University is good for pharmacy and not so much for MBA Agribusiness. The placement reports are not good for either of them and i recommend you to try for top MBA colleges through entrance exams for better placements.  The placement report is as follows:

Integral University - Average- 2.4 LPA

SHUATS- Average- 4.2 LPA
