A field trial was carried out to investigate the effect of seed priming on the productivity of late sown wheat during fall-2016. The experiment was laid out in randomized complete block design (RCBD) with split-plot arrangement having three replications. Two factors (sowing dates and priming) were tested in the experiment. Sowing dates (29th Oct, 10th Nov, 24th Nov, 10th Dec, 26th Dec and 10th Jan) were assigned to main plots, while priming (non-primed and primed) was allotted to sub-plots. Wheat variety “SIRAN-2010” was sown in a plot size of 1.8m x 5m. Results showed that wheat crop sown on 29th Oct resulted in early emergence (6 days), increased emergence m-2 (139) plant height (101.61cm), spikes m-2 (280), grains spike-1 (46.63), thousand grain weight (44g), biological yield (9770 kg ha-1) and grain yield (4038 kg ha-1). Late sown wheat in (10th Jan) took lesser days (136) to maturity. In case of seed priming early emergence (11 days), more emergence m-2 (102), taller plants (85.19cm), more spikes m-2 (216), higher grains spike-1 (40.18), maximum 1000-grains weight (37g), maximum grain yield (3116 kg ha-1) and maximum biological yield (7630 kg ha-1) was recorded in plots sown with hydro-primed seed. However, dry sown seed took more days (163) to emergence. Hence it is concluded that sowing from 29th Oct to 10th Nov significantly increased yield and yield related components of wheat. Similarly seed priming is necessary for higher yield of late sown wheat.
