Applying to masters vs directly applying to PhD? I have just completed my BSc. Agriculture (3.6/4GPA). and initially I wanted to do masters in horticulture or crop modeling but now since I see myself doing phd down the line, is it better to apply for phd directly? do admission committe even conisder bsc graduate seriously for phd? 
I have a couple of conference paper and have two papers under review (one on plant pathology and  other on agriculture cooperatives).
taken the ielts test( overall band 8.0) and taking gre on november (expecting 310-320).  I am so confused.
