Bio-Priming of Soybean with <i>Bradyrhizobium japonicum</i> and <i>Bacillus megaterium</i>: Strategy to Improve Seed Germination and the Initial Seedling Growth

Bio-priming is a new technique of seed treatment that improves seed germination, vigor, crop growth and yield. The objective of this study was to evaluate the effectiveness of <i>Bradyrhizobium japonicum</i> (commercial strains) and <i>Bacillus megaterium</i> (newly isolated...

description Bio-priming is a new technique of seed treatment that improves seed germination, vigor, crop growth and yield. The objective of this study was to evaluate the effectiveness of <i>Bradyrhizobium japonicum</i> (commercial strains) and <i>Bacillus megaterium</i> (newly isolated strains) as a single inoculant and co-inoculant during seed bio-priming to improve seed germination and initial seedling growth of two soybean cultivars. The treated seeds were subjected to germination test (GT), cold test (CT) and accelerated aging test (AAT). <i>B. megaterium</i> significantly improved all parameters in GT and CT; final germination, shoot length, root length, root dry weight, and seedling vigor index in AAT, as compared to control. In addition, co-inoculation significantly increased all parameters except shoot dry weight in GT; all parameters in CT; germination energy, shoot length, root length, and seedling vigor index in AAT, in comparison to the control. Moreover, <i>Br. japonicum</i> significantly improved the germination energy, shoot length, shoot dry weight, root dry weight, and seedling vigor index in GT; all parameters in CT; shoot length, root length, and seedling vigor index in AAT, compared with non-primed seeds. Thus, <i>B. megaterium</i> strains could be used in soybean bio-priming as a potential single inoculant and co-inoculant, following proper field evaluation.
