To the effect of seed priming treatments on growth parameters and seed quality of wheat (Triticum aestivum L.) under rainfed conditions

The present study was conducted on wheat variety “K-1317”and was procured from Student instructional Farm, C.S. Azad University of Agriculture & Technology, Kanpur. The experiment was conducted in Rabi 2022-23 and 2023-24. The seeds were used for pre-sowing seed treatments, T₀ Control (Un soaking), T₁ Soaking with tap water for 12 hrs, T₂ Soaking with tap water for 24 hrs, T₃ Soaking with Bacillus Subtilis for 12 hrs, T₄ Soaking with Bacillus subtilis for 24 hrs, T₅ Soaking with Azotobacter for 12 hrs, T₆ Soaking with Azotobacter for 24 hrs, T₇ Soaking with NaCl @ 1% for 12 hrs, T₈ Soaking NaCl @ 1% for 24 hrs, T₉ Soaking with ZnSo₄ @ 1% for 12 hrs, T₁₀ Soaking with ZnSo₄ @ 1% for 24 hrs, T₁₁ Soaking with GA₃ @ (50 ppm) for 12 hrs, T₁₂ Soaking with GA₃ @ (50 ppm) for 24 hrs & T₁₃ Soaking Auxin (IAA) @ (50 ppm) for 12 hrs & T₁₄ Soaking IAA @ (50 ppm) for 24 hrs. Pre-sowing seed treatment or priming was done by soaking of required quantity of seeds of wheat variety K- 1317 in tap water, biologicals, chemicals, and hormonals’ treatments in given concentration for 12 hrs and 24 hrs in ratio of 1:1 (Kg of seeds/volume of solution) by using wet gunny bags. Then the treated or primed (soaked) seeds were dried in shade to maintain the seed moisture content approximately 12 or 13%. Seed dressing was done on primed and untreated (control) by Thiram (2.5%). Seeds priming was GA₃@ (50 ppm) for 12 hrs on wheat variety K-1317 significantly present results the growth attributes and seed quality. The best results in found under the treatment T₁₁ Initiation of headings, Days to 50% headings, Days to maturity, Grain yield kg/plot Seed moisture content (%) at the time of sowing and Moisture content (%) in seed but the most superior result shown by T₁₃ on Field moisture content (%) at the time of sowing in season 2022 and 2023. and the at par treatments T₃, T₁₀, T₁₂, T₁₃ and T₁₄.
