Relationship between Seed Priming Mediated Seedling Vigor and Yield Performance of Spring Wheat

Seed priming is a pre-germinated technique that can enhance seed germination percentage, faster and synchronized germination, better seedling growth, and yield under stress conditions. To ascertain the most effective seed priming method that would ensure the potential yield of wheat in Bangladesh, two experiments were carried out from December 2021 to March 2022 at the Department of Agronomy, Bangladesh Agricultural University. Two wheat varieties namely BARI Gom-28 and BWMRI Gom-1 were subjected to a range of priming chemicals in both lab and pot tests. These compounds included the following: control (no priming), hydropriming (distilled water), 10000 ppm KNO3, 15000 ppm KNO3, 40000 ppm Mannitol, 60000 ppm Mannitol, 10000 ppm NaCl, 20000 ppm NaCl, 100 ppm PEG, 150 ppm PEG, 500 ppm NaOCl, 1000 ppm NaOCl, 10000 ppm CaCl2, 20000 ppm CaCl2, 10000 ppm KCl and 20000 ppm KCl. A complete randomized design (CRD) with three replications was used to set up the experiments. The results showed that BARI Gom-28 and BWMRI Gom-1 responded best to KCl priming in terms of rapid seed germination and strong seedling development. On the other hand, the best priming agents for plant growth and productivity turned out to be CaCl2 and KCL. The results of this study support the possibility of using seed priming as a technique to improve wheat plant development and output by raising seed emergence and survival rates.
