Abstract
Diverse seed priming methods are used to ameliorate seed germination, seedling vigour, and to overcome abiotic stress. Insertion to these, only the bio-priming system provides the fresh benefit of biotic stress operation, earning it special attention. Bio-priming is applicable in nearly all crops around the world and is an environmentally friendly volition to chemical pesticides. Seed bio-priming generally refers to use of salutary microorganisms to influence germination potential. In this study, Rhizobium leguminosarum were used in different concentration following Complete Randomized Design with three replications. Green gram (TMB-37) was collected from AICRP pulses in BCKV, Mohanpur, Nadia, West Bengal for this investigation. The experiment comprised of seven bio-priming treatments along with control. The seeds were subjected to in-vitro studies and data were analysed statistically. Seed bio-primed with Rhizobium leguminosarum @ 20 percent recorded higher seed germination percentage (82.71 %), shoot length (25.49 cm), seedling fresh weight (2.77 g), seedling dry weight (0.24 g), seedling vigour index I (3467.91) and seedling vigour index II (19.85). The results of this study demonstrated that Rhizobium leguminosarum @ 20 percent was the best.
