Microbial fertilizers containing Bacillus subtilis and Bacillus megaterium isolates are one of the important organic fertilizers, which strengthen the immune system of plants against harmful effects and promote the plant growth by fixing nitrogen from the atmosphere, to obtain better quality products. This study was conducted to determine the effects of different liquid microbial fertilizer doses (0, 500, 1000, 1500, 2000, and 2500 ml 100 L–1) on the yield and yield components of the coriander (Coriandrum sativum L.) grown in Bayburt in 2018 and 2019. The experiment was set up as three replicates in randomized complete block design. The results indicated that there was a considerable variation in the yield and yield components of coriander, and the yield significantly increased as the dose of microbial fertilizer was increased. The maximum essential oil content and seed yield were recorded for the plots grown under the F1 and F3 treatment. It was found that the maximum seed yield was obtained in the F3 treatment (839.0 kg ha–1), and the seed yield decreased in the F4 (754.1 kg ha–1) and F5 (759.9 kg ha–1) treatments. Although the increase in the microbial fertilizer dose increases seed yield, using the fertilizer in optimum dose can be more profitable. Therefore, this study suggests that the fertilizer dose “F3” can improve the productivity of the coriander grown in the areas treated with microbial fertilizer.
