Increased plant population causes more in-row stress in plants, potentially reducing yield. Narrow row spacing can reduce stress by increasing plant-to-plant spacing within a row. Therefore, it is important to standardize plant row spacing according to various characteristics to achieve higher yield and quality. The purpose of the 2014–2015 study was to ascertain the impact of varying sowing distances (20, 30, 40, and 50 cm) between rows on the yield and agronomic traits of coriander genotypes (Gamze, Kudret, Telci). Four replications of the field research were set up using a "Randomized Blocks Experimental Design." The results indicated that genotype, row spacing, and the genotype x row spacing interaction had a statistically significant impact on seed output, but the years had no discernible influence on seed yield. The production of seed and oil decreased as row spacing increased, while oil content increased. With 20–40 cm row spacing and 1683.4–1846.5 kg da-1, the genotypes of Kudret and Telci produced the maximum seed production. Although the decrease in the number of branches and umbrellas in narrow row spacing had a negative effect on seed yield, the increase in the number of seeds per umbrella and the number of plants per unit area led to an increase in seed yield. When evaluated based on genotypes, although the Kudret and Telci genotypes gave the best results in terms of seed yield, the Kudret genotype gave the best results regarding essential oil ratio and essential oil yield.

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.
