Diploma

Yes, you can get admission, but firstly, you need to apply for it and then you have to give CET exam after that you will get admission.

You can go for further studies or get a job related to it.

Yes, you will need to take the entrance test, interview, group discussion just like a normal 10+2 candidate and then pursue a Bachelor's degree. Just a personal recommendation, consider taking some hands-on experience after Diploma and then do a Bachelor's degree. Diploma entitles you for job opport

After 10th, it is difficult to get admission in a business course. It requires +2 or Bachelor's degree. So, first, you complete it and then you will get admission in a business course.

I recommend you, to do 10+2, and then do a degree in agriculture sciences and technology.

Diploma courses are available across wide range of disciplines such as, Engineering, medical and laboratory sciences, designing, beauty and fitness, computer applications, animation, fashion technology, media and entertainment. Check your interest and then pick the subject.
