DAS, days after sowing. Mix: Mix of Priestia megaterium B004 + Azotobacter chroococcum A004 with zeolite as a carrier. Means followed by the same letter for treatments are not significantly different according to Duncan test (p < 0.05). Values presented are mean values of three replicates ± standard deviation. Significance levels: *** p < 0.001, ** p < 0.01.
