Investigation of the effects of some bacterial isolates and fertilizer applications on nutrient contents of hyacinth

Abstract

This study was conducted to determine the effect of NPK fertilization and some bacterial species on the macro and micro nutrient element contents of Hyacinthus orientalis cv. ‘Delft Blue’ leaves and bulbs. 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. Nitrogenfixing bacteria: Cellulomonas turbata (TV54A), phosphate solibilizing bacteria: Bacillus-GC Group (TV119E), nitrogen-fixing and phosphate solibilizing bacteria: Kluyvera cryocrescens (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-1;potassium (K) 4.534%; iron (Fe) 152.453 mgkg-1; manganese (Mn) 26.739 mgkg-1; zinc (Zn) 46.517 mgkg-1and copper (Cu) 8.902 mgkg-1 (P <0.01) in hyacinth leaves, while calcium (Ca) was 1064.95 mgkg-1 and magnesium (Mg) was found 1992.92 mgkg-1, and the difference between the mean values for these two elements was not statistically significant. 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-1; K, 2.203%; Ca 2322.045 mgkg-1; Mg 1884.164 mgkg-1; Mn 39.640 mgkg-1; Zn was obtained as 40.861 mgkg-1 and Cu 7.683 mgkg-1, whereas Fe was found to have an average value of 140.545 mgkg-1. 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.
