What is the maximum time for watchdog timer to reset. I am using

 WDTCTL = WDT_ARST_1000;   line to reset my watchdog timer for 1 sec time delay. Is it possible to extend upto 3 secs

    You'd have to use a slower clock. You could run ACLK from the VLO, or SMCLK from a very slow DCO, and divide them down with DIVA/DIVS. (This does not work if you need these clocks to be faster for other things.)
