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.
