In the study carried out under laboratory conditions, according to randomized plot experiment design, full and 50% dose of 20:20:20 NPK commercial fertilizer was applied to hyacinth bulbs as inorganic fertilizer. Nitrogen-fixing bacteria: <em>Cellulomonas turbata</em>&nbsp;(TV54A), phosphate solibilizing bacteria:&nbsp;<em>Bacillus</em>-GC Group (TV119E), nitrogen-fixing and phosphate solibilizing bacteria:&nbsp;<em>Kluyvera cryocrescens</em>&nbsp;(TV113C)were used as biological fertilizers. In this study, the highest mean values of nutrients were obtained as nitrogen (N) 3.866%; phosphorus (P) 334.790 mgkg<sup>-1</sup>;potassium (K) 4.534%; iron (Fe) 152.453 mgkg<sup>-1</sup>; manganese (Mn) 26.739 mgkg<sup>-1</sup>; zinc (Zn) 46.517 mgkg<sup>-1</sup>and copper (Cu) 8.902 mgkg<sup>-1</sup>&nbsp;(P &lt;0.01) in hyacinth leaves, while calcium (Ca) was 1064.95 mgkg<sup>-1&nbsp;</sup>and magnesium (Mg) was found 1992.92 mgkg<sup>-1</sup>, and the difference between the mean values for these two elements was not statistically significant.&nbsp; The highest N, P, Zn and Cu contents of the leaf were obtained by using full dose NPK. The highest mean values of nutrient elements in hyacinth bulbs were 4.382%; P 278.496 mgkg<sup>-1</sup>; K, 2.203%; Ca 2322.045 mgkg<sup>-1</sup>; Mg 1884.164 mgkg<sup>-1</sup>; Mn 39.640 mgkg<sup>-1</sup>; Zn was obtained as 40.861 mgkg<sup>-1</sup>&nbsp;and Cu 7.683 mgkg<sup>-1</sup>, whereas Fe was found to have an average value of 140.545 mgkg<sup>-1</sup>. In the process of bacteria inoculation K, Ca and Mg content of inoculation; N, P, Mn, Zn and Cu content of ½ NPK fertilization was determined to be effective.</p> ER -
