Evaluating the Effect of Seed Priming Treatments on Yield and Quality of Wheat Seed (Triticum aestivum L.) under Rainfed Conditions

Abstract

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 12hrs, T2 Soaking with tap water for 24hrs, T3 Soaking with Bacillus Subtilis for 12hrs, T4 Soaking with Bacillus subtilis  for 24hrs, T5 Soaking with Azotobacter for 12hrs, T6 Soaking with Azotobacter for 24hrs, T7 Soaking with NaCl @1% for 12hrs, T8 Soaking NaCl @1% for 24hrs, T9 Soaking with ZnSo4 @1% for 12hrs, T10 Soaking with ZnSo4 @1% for 24hrs, T11 Soaking with GA3 @(50ppm) for 12hrs, T12 Soaking with GA3 @(50ppm) for 24hrs & T13 Soaking Auxin (IAA) @(50ppm) for 12hrs & T14 Soaking IAA @(50ppm) for 24hrs. 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 concentration for 12hrs and 24hrs 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@ (50ppm) for 12hrs on wheat variety K-1317 significantly present results the yield and quality of seed. The best results in found under the treatment T11 Soaking with GA3 @(50ppm) for 12hrs, in productive tillers, number seeds/spike, number of spikelet’s/spikes, spike length, grain yield and harvest index, protein content in 2022-2023. and the at par treatments T10, T12, T13 and T14.
