Abstract:
The present experiment was conducted during rabi 2022-23 at H block Main Agricultural Research Station, University of Agricultural Sciences Dharwad. The experiment comprised of nine different treatments with three replications in randomized block design. Before sowing seeds were treated with different fungicides at different concentrations to control seed borne infections in Durum wheat. viz., T₁: Control (Untreated), T₂: Seed treatment with Carboxin 37.5%+ Thiram 37.5% @ 0.3%, T₃: Seed treatment+ foliar spray with Carboxin 37.5%+Thiram 37.5% @ 0.2%, T₄: Foliar spray with Propiconazole @ 0.1% at 30 DAS, T₅: Seed treatment with Penflufen 13.28%+ Trifloxystrobin 13.28% @ 0.2%, T₆: Seed treatment with Penflufen 13.28% + Trifloxystrobin 13.28% @ 0.2% and foliar spray with Propiconazole @ 0.1% at 30 DAS, T₇: Seed treatment with Thiophanate methyl 45% + Pyroclrostrobin 5% @ 0.2%, T₈: Seedtreatment with Carbendazim 50% WP @ 0.2%, T₉: Seed treatment With Carbendizim 25% + Mancozeb 50% @ 0.2%. Durum wheat seeds of the variety UAS – 446 were collected from seed unit, Main Agricultural Research Station, UAS, Dharwad Karnataka. After harvest seeds were collected and recorded seed quality parameters such as germination (%), root length (cm), shoot length (cm) and seedling vigour index. Further the data obtained was subjected to statistical analysis. The results revealed that among different seed treatments, seeds treated with Carbendazim 50%+ Mancozeb 25% WS @ 0.2% recorded significantly higher germination (90.33%), root length (17.06 cm), shoot length (14.82 cm) and increased seedling vigour index (2878) followed by seeds treated with Carbendazim 50% compared to control (80.00%), (12.54 cm), (10.07 cm) and (1939) in Durum wheat.
