We have studied low-frequency (45 - 410 MHz) type III solar radio burstsobserved using the e-CALLISTO spectrometer located at Gauribidanur radioobservatory, India during 2013 - 2017. After inspecting the 1531 type IIIbursts we found that 426 bursts were associated with flares, while the otherbursts might have triggered by small scale features / weak energy eventspresent in the solar corona. In this study, we have carried out a statisticalanalysis of various observational parameters like start time, lower andupper-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 thehigh-frequency bursts (whose upper-frequency cut-off $> 350$ MHz) areoriginated from the western longitudes. We interpret that it could be due tothe fact that Parker spirals from these longitudes are directed towards theearth and high-frequency bursts are more directive. Further, we report thatnumber of bursts that reach earth from western longitudes are higher thaneastern longitudes.
