We report the upgraded Giant Metrewave Radio Telescope (uGMRT) radio observations of supernova SN 2023ixf in M101. Our observations took place on 2023 May 22.74 UT in uGMRT band 5 (1000-1450 MHz) at a central frequency of 1255 MHz. We find no evidence of radio emission from SN 2023ixf above a 3-sigma upper limit of 75 microJy at the position of the optical position of the supernova. Our flux density upper limit corresponds to a 3-sigma upper limit to the monochromatic luminosity of 3.7E24 erg/s/Hz. We thank the staff of the GMRT that made these observations possible. More observations are planned.
