Assessing the effects of Different Biofertilizer Levels on Dry-weight of Wheat and Barley Cultivars at Maturity Stage
The current study was conducted to investigate the effect of biofertilizers on some physiological and agronomical characteristics of different varieties of wheat and barley at the physiological maturity stage in 2021 at the new campus of Gorgan University of Agricultural Sciences and Natural Resources. The experiment was a Completely Randomized Factorial Design with two factors; the first factor was the inoculation of biofertilizer at three levels (Barvar-2, Actinomycetes, Barvar-2 + Actinomycetes), and the second factor was wheat and barley at 14 levels (eight varieties of wheat: Marwarid, Gonbad, Karim, Ihsan, Darya, N-91-8, N-91-9, and N-91-17 and six varieties of barley: Mahor, Torkman, Sahra, Boomy, Yusuf, and Lukht) all with three replications. Results indicated that the effect of genotype on all the traits considered in this study (leaf dry weight, stem, root, shoot, and total) was significant at a 1% level of confidence and that barley (Boomy and Sahra cultivars) had higher amounts of dry weight. On the other hand, biofertilizer did not reveal a significant effect on the traits; however, the interaction of genotype and biofertilizer indicated a significant effect on the dry weight of roots, and the highest amount was found in Marwarid genotype and actinomycetes experiment.
