  We present the results from the low-frequency (40--78 MHz) extension of the
first LOFAR pulsar census of non-recycled pulsars. We have used the Low-Band
Antennas of the LOFAR core stations to observe 87 pulsars out of 158 that have
been detected previously with the High-Band Antennas. Forty-three pulsars have
been detected and we present here their flux densities and flux-calibrated
profiles. Seventeen of these pulsars have not been, to our knowledge, detected
before at such low frequencies. We re-calculate the spectral indices using the
new low-frequency flux density measurements from the LOFAR census and discuss
the prospects of studying pulsars at the very low frequencies with the current
and upcoming facilities, such as NenuFAR.
