THE EFFECTS OF DOSAGES OF WORM AND NITROGEN-PHOSPHORUS FERTILIZERS ON NUTRIENT CONTENT OF HYACINTHUS ORIENTALIS L. CV. PURPLE STAR IN ECOLOGICAL CONDITIONS OF SIIRT, TURKEY

Abstract

This study was carried out on the campus of Siirt University, Turkey between 2016-2017 years. Solid worm fertilizer at dosages of 25 g/bulb (V1), 50 g/bulb (V2), 75 g/bulb (V3) and 2 kg/da (NP1), 4 kg/da (NP2), 8 kg/da (NP3) Nitrogen-Phosphorus (NP) were applicated on hyacinth (Hyacinthus orientalis L. cv. Purple Star). At the end of study, plant nutrient elements were determined on the leaves and bulbs of plants. According to leaf analysis results, nitrogen (N), phosphorus (P), potassium (K), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) contents were found significant (p<0,01) statistically and between 2,403-4,450%, 0,269-0,603%, 3,112-6,758%, 802,33-31520,657 mg kg(-1), 46,253-88,585 mg kg(-1), 15,14833,560 mg kg(-1) and 8,582-18,616 mg kg(-1) respectively except calcium (Ca) and magnesium (Mg) contents were determined between 0,775-1,130% and 0,239-0,346% respectively. In leaves the highest mean contents of N, P, K, Mg and Cu were found on V3 while Zn was found on V1 while Fe, Mn and Ca were found on NP3 treatments. On the other hand, on P, Fe and Zn (P<0,01) and K (P<0,05) were found significant statistically, except N, Ca, Mg, Mn and Cu on bulbs. As well as the highest mean contents of N, P, K and Mg were found on V3 while Mn, Zn and Cu were found on V1; Fe was obtained on control and Ca was obtained V3 and NP2 treatments. The means of nutrient elements as N 1,063-1,713%, P 0,191-0,337, K 0,817-1,183%, Ca 0,287-0,372%, Mg 0,089-0,119 %, Fe 169,540-482,209 mg kg(-1), Mn 12,410-23,374 mg kg(-1) Zn 7,390-18,556 mg kg(-1) and Cu 4,711-6,949 mg kg(-1) were determined.
