Visitor Visa - B2

I have applied for B2 visa in April, 2014, was denied for 214b reason. I'm single 30 year old last name patel. I have applied for my self only and i showed 65 thousand monthly income in farming. I have a cousin in US who sent me an invitation letter to visit famous tourist place for 3 weeks. And i have also been to UK 4 years ago for 5 months. What was the reason for denial. I m trying to reapply again. If you would help me what changes i need to make. I also have a job but did not mention that and only mentioned for the farming income.

VO: Good Morning
Me: Good Morning Sir

VO: So you've been to UK, What did you do in UK
ME: I have been there for 5 months and been to many places.

VO: Who is there in UK
ME: My cousin and she sponsored me

VO: Do you have any one in USA
ME: my cousin in US and he invited me

VO: What does he do in US:
ME: He is a manager in a motel

VO: Who are you traveling with?
ME: Myself only

VO: I'm sorry but we cannot grant you a visa this time

If you would please let me know what was the denial reason.? They did not even answer me about my purpose to US visit, mainly asked about my UK trip..
