SUMMARY

The experiment was carried out at CCS HAU, Regional Research Station, Bawal during Rabi, 2023-24 to study the effect of seed priming on wheat under late sown condition. The experiment was comprised of thirteen Seed priming (SP) treatments viz., SP₁: Control, SP₂: Water @ 6hr (hours), SP₃: Water @ 9hr, SP₄: Water @ 12hr, SP₅: KH₂PO₄ @ 1% 6 hr, SP₆: KH₂PO₄ @ 1% 9 hr, SP₇: KH₂PO₄ @ 1% 12hr, SP₈: KNO₃ @ 1% 6 hr, SP₉: KNO₃ @ 1% 9hr, SP₁₀: KNO₃ @ 1% 12hr, SP₁₁: GA₃ @ 50 ppm 6hr, SP₁₂: GA₃ @ 50 ppm 9hr and SP₁₃: GA₃ @ 50 ppm 12hr. Among various treatments, seed priming of wheat with KH₂PO₄ @ 1% 12 hr took minimum number of days to emergence (6.03), anthesis (71.60), grain filling (85.69) and physiological maturity (120.89), while maximum days were taken by control treatment with respect to days to emergence (10.00), anthesis (75.90), grain filling (95.66) and physiological maturity (126.92). Maximum number of grain/spike (50.90), 1000 grain weight (41.61 g), grain yield (49.14 q/ha), straw yield (93.82 q/ha) and biological yield (142.96 q/ha) were obtained by seed priming of KH₂PO₄ @ 1% 12 hr followed by KNO₃ @ 1% 12 hr, while minimum no. of grain/spike (46.33), 1000 grain weight (36.30 g), grain yield (45.64 q/ha), straw yield (84.77 q/ha) and biological yield (130.41 q/ha) were recorded in control. highest gross returns, net returns and B:C ratio was recorded in case of KH₂PO₄ @ 1% 12 hr (Rs. 144,185/ha, Rs. 61,749/ha and 1.75, respectively). While, lowest gross return, net return and B:C ratio was recorded in control (Rs. 132,850/ha, Rs. 51,912/ha, and 1.64, respectively).
