Can I create nodes through drush for particular content type
Just a note to point out a new module called Faker which can be used in conjunction with Devel Generate :


  Use the PHP Faker library to generate more meaningful sample content.
  
  Devel Generate is great for creating a lot of sample content in a
  hurry, but sometimes you want samples that are more meaningful, or
  closer to the content you expect users to generate. This is where
  Faker comes in.
  
  Faker is a PHP library that generates fake data for you
  
  Faker (the library) can generate real looking names, addresses,
  emails, domains and more. Faker (the module) combines the library with
  quick content creation abilities provided by Devel Generate, to give
  you the power to easily generate real looking sample content.
