The present investigation entitled “Performance of wheat varieties under restricted irrigation” was conducted during Rabi season of 2019-20at university research farm Bihar Agricultural University, Sabour, Bihar, India to find out the effect of restricted irrigation on yield and yield attributes of different wheat varieties. The experiment was laid out in split plot design with three replication. The treatment consisted of three levels of irrigation (I1 – No irrigation, I2 – One irrigation at CRI stage, I3 – Two irrigation at CRI and boot leaf stages) in main plot and six varieties viz.DBW252, HD3171, HI1612, HD2888, HD3293, and K1317 placed in sub plot. Regarding irrigation levels maximum number of earhead/m2 (312.94), length of ear head (12.25 cm), number of grains/ ear head (44.06) and 1000 grain weight (42.05 g), grain (42.88 q/ha), straw (55.67 q/ha), biological yield (98.56 q/ha) and harvest index (0.44 %) were recorded under two irrigation (I3) given at CRI and boot leaf stages, which was which was statistically at par with one irrigations (I2) given at CRI stage. Among the different wheat varieties, HD3171 were recorded with maximum number of earhead/m2 (312.94), length of ear head(12.25 cm), number of grains/ ear head(44.06) and 1000 grain weight(42.05 g), grain (43.83 q/ha) and (57.18q/ha), biological yield (101.24) and harvest index (0.45) followed by DBW252 and HI1612.
