  "abstract": "We present a search for radio pulses from the Galactic magnetar SGR 1935+2154, a well-known source of fast radio bursts (FRBs), at $\\sim$110 MHz using the Large Phased Array (LPA) of the Pushchino Radio Astronomy Observatory. Data from two active periods in 2020 (March -- May and September -- November, with $\\sim 3.5$ minutes of daily coverage) were analyzed with new methods tailored to both FRB-like single pulses and pulsar-like periodic signals. No significant FRB-like pulses were found. Using Monte Carlo simulations, $3σ$ upper limits were derived for the burst rate: for a log-normal energy distribution the limit is $\\sim$${10}^{1.5}~{\\rm{d}}^{-1}$ for a mean of average monochromatic isotropic luminosity $L_{ν{\\rm ,mean}}\\sim1.3\\times{10}^{29}~{\\rm{erg~s^{-1}~ {Hz}^{-1}}}$ and a natural log-space scatter of $σ\\sim0.85$; while for a power-law distribution it is $\\sim$${10}^{1.8}~{\\rm{d}}^{-1}$ for an index $β\\lesssim3.0$ and a minimum average monochromatic isotropic luminosity $L_{ν{\\rm{,min}}}\\lesssim0.7\\times{10}^{25}~{\\rm{erg~s^{-1}~{Hz}^{-1}}}$. When folded at the known 3.24781628 s period of SGR 1935+2154, a weak pulse was noted (S/N $<$ 3.16), but the significance is insufficient for a secure detection of the pulsar-like emission signal. A conservative upper limit on the average monochromatic isotropic luminosity of any possible periodic emission is $2.08\\times{10}^{19}~{\\rm{erg~s^{-1}~{Hz}^{-1}}}$. Our results offer meaningful low-frequency upper limits on the burst rate of SGR 1935+2154, and hint for very faint pulsar-like radiation at meter wavelengths.",
