You are a HR and then IR personnel, as per your profile, and could have handled the situation much better.
You have posted that:
---“ I have never did any correspondance with Management due to fear of loosing job immideatly and they will also spoil my career by adapting such unfair practices.”
Forced resignation can be termed offence.
There is never any need to be fearsome and fearful and afraid of anything.
Employee should be skillful and vigilant and can achieve his/her objectives by remaining amiable, gentle too.
You have already lost the job.
You have presented your resignation on a platter to the unscrupulous employer.
Probably you have not generated and saved irrefutable evidence of forced resignation for use at appropriate time in appropriate forum, if the need be.
Had you mustered courage to do so you could have negotiated very well on your own by applying some skills or thru your counsel(s) without any adverse effect on you, and resolved the situation in your favor!
---“ The Management has conveyed that company is suffering from recession and manpower reduction is required to servival of company. They have asked me to submit my resignation and accordingly I have also submitted the same as per management's wish.”
Apparently all such communications to you were verbal. Although a fair employer would not mind communicating in writing. At the most employer would have to tender compensation as per service conditions.
There was no need to write the resignation at once, on the spot.

---“ In the month of May 2015 Management have declared normal increment with effect from April 2015 to all employees except me. and immediatly after declaring the increment management also reduced 30% salary of all employees and it is including me.”
The declaration of increment is by a circular or individual communication, in writing?
How the salary has been reduced? By some one way communication in writing, or negotiations? Has the company obtained the acceptance of reduction in writing? Are all of affected employees covered by PF?
---“ Should I be entitle for normal increment after submission of resignation and recover the arrears?”
What is the process? Some appraisal? If yes was any appraisal conducted with each employee?
