Thanks Mr. Hesam for your nice suggestions. 

Canada is a great option! a lot of scholarships specially in agriculture area!

Dear  Zayda Morales Moreira,

Thanks. I think IELTS is mandatory in Canada and right now I don't have.

Dear M. Hesam Shahrajabian,

Thanks for putting some great information. In fact, I have been already in Europe and could be better to do PhD here but difficult to find a PhD fund a supervisor. 

Jasim in Canada could be also TOEFL that is less complex also here most of the programs in Agriculture offer Graduate Stipend to PhD students. 

Zayda Morales Moreira. Thanks for your inspiration. I am gonna try.

You well done Jasim, you can join to Huazhong Agriculture University , Wuhan,  China
