  We present the results of photometry, linear spectropolarimetry, and imaging
circular polarimetry ofcomet C/2009 P1 (Garradd) performed at the 6-m telescope
BTA of the Special Astrophysical Observatory(Russia) equipped by the multi-mode
focal reducer SCORPIO-2. The comet was observed at two epochspost-perihelion:
on February 2-14, 2012 at r=1.6 au and {\alpha}=36 {\deg}; and on April 14-21,
2012 at r=2.2 au and {\alpha}=27 deg. The spatial maps of the relative
intensity and circular polarization as well as the spectral distribution of
linear polarization are presented. There were two features (dust and gas tails)
orientedin the solar and antisolar directions on February 2 and 14 that allowed
us to determine rotation periodof the nucleus as 11.1 hours. We detected
emissions of C2 , C3 , CN, CH, NH2 molecules as well as CO+ and H2O+ ions,
along with a high level of the dust continuum. On February 2, the degree of
linear polarization in the continuum, within the wavelength range of 0.67-0.68
{\mu}m, was about 5% in the near-nucleus region up to near 6000 km and
decreased to about 3% at near 40,000 km. The left-handed (negative) circular
polarization at the level approximately from -0.06% to -0.4% was observed at
the distances up to 3*10^4 km from the nucleus on February 14 and April 21,
respectively.
