  We have studied low-frequency (45 - 410 MHz) type III solar radio bursts
observed using the e-CALLISTO spectrometer located at Gauribidanur radio
observatory, India during 2013 - 2017. After inspecting the 1531 type III
bursts we found that 426 bursts were associated with flares, while the other
bursts might have triggered by small scale features / weak energy events
present in the solar corona. In this study, we have carried out a statistical
analysis of various observational parameters like start time, lower and
upper-frequency cut-offs of type III bursts and their association with flares,
variation of such parameters with flare parameters such as location, class,
onset and peak timings. From this study, we found that most of the
high-frequency bursts (whose upper-frequency cut-off $> 350$ MHz) are
originated from the western longitudes. We interpret that it could be due to
the fact that Parker spirals from these longitudes are directed towards the
earth and high-frequency bursts are more directive. Further, we report that
number of bursts that reach earth from western longitudes are higher than
eastern longitudes.
