B.Tech Food Technology

All three are different fields from one another. One can make a better career with his hard work and interest in the subject. Don't decide on the basis of good career but decide on the basis of inclination towards the subjects. Agriculture is about the rearing of livestock, farming activities, with job based in rural or semi-rural areas as marketing officer. Food technology deals with the food safety, catering and food handling in different business operations. Pharmacy is a paramedical field which studies about the drugs and medicines and it's related aspects such as manufacturing, labeling, storage, marketing, etc. Master's degree with Ph.D in respective fields will make you eligible for a teaching career in educational institutes. All the best.
