Abstract: We have reported the detection of Off-pulse emission in Basu et al. (2011) in two long period pulsars B0525+21 and B2045–16 at 325 MHz using the Giant Metrewave Radio Telescope. We have extended our studies to detect Off-pulse emission in two more pulsars B1237+25 and B0834+06 at 325 MHz. We also report the detection of Off-pulse emission in B0525+21 and B2045–16 at 610 MHz. The long periodicity and low spin down energies of the pulsars studied make it highly unlikely for the detected emission to be due to Pulsar Wind Nebulae. The location of the Off-pulse emission far away from the On-pulse on the other hand gives rise to interesting questions about the structure of the pulsar magnetosphere and the emission mechanism if the Off-pulse emission is magnetospheric in origin.
