Hi, according to the query, the field of "scope" is incomplete. Hence, i would like to compare the 2 branches on both aspects- placement and higher studies. As far as placement is considered, Information technology is a highly demanding branch while biotechnology is an "increasing in demand day by day" type branch.Hence as expected, higher salaries are given in IT . Now if we talk about higher studies, both have equal opportunities provided you give your best shot while in B.tech.

After doing Btech in Information Technology the students can join in companies as :

•  Web Developer
• Designer Data Security Officer 
• Database Manager 
• Software Developer
• Information Technology Engineer

Biotechnology is a rapidly developing field. Many private businesses are exploring this field and heavily investing in it. It is safe to say that there are ample job opportunities for B.E./B.Tech. Biotechnology Graduates in the private sector. Government sector too offers job opportunities, but not in the scale in which the private sector does. Average starting salary is generally between 2.4 to 5 Lakh Rupees per year.

Some prominent industries where Biotechnology professionals may find jobs are- Pharmaceuticals Industry, Healthcare sector, Chemical Industry, Agriculture sector, Food Processing and Technology as well as Research sector. Graduates may also take up teaching job (as lecturer) after completing M.E./M.Tech. program.
