Dear student,
 
Certainly yes. When you apply a force on the blackboard, the blackboard also applies equal and opposite force on you.
 
As, Newton's 3rd law states that for every action there is an equal and opposite reaction. In other words, when one object exerts a force on another object, the second object exerts a force of equal strength in the opposite direction on the first object. 
 
Hope this helps.
