Rasheed;  
Hope all is well in Pakistan. Watch irrigation during excess heat - 'scald' will kill plants (lack of oxygen during flood).  
You can try overseeding in late fall cooler conditions, but after light harrow. Warning - not always highly successful. Analyze what killed plants initially. low spots? Drainage? disease? Recruiting young seedlings can work short term, but what killed the plants initially may kill them again. However, on young stands, it can work.  
Cheers,  
Dan
