  Magnetic, magnetocaloric and magneto-transport properties of polycrystalline
HoNiSi have been studied. The compound crystallizes in orthorhombic crystal
structure and orders antiferromagnetically at TN=4.6 K. Magnetization isotherms
show curvature at small fields, revealing a field induced metamagnetic
transition. Magnetocalroic effect (MCE) has been estimated using magnetization
data and is found to be 12.8 J/kg K for a field of 50 kOe. Application of field
reduces the resistivity near TN, which results in a large negative MR. The
maximum value of MR has been found to be -24% at 4 K for 50 kOe. Below 4 K, the
compound shows positive MR with shape changing with field.
