THE EFFECTS OF DOSAGES OF VERMICOMPOST AND NP ON PLANT GROWTH AND NUTRIENT CONTENT OF HYACINTH (Hyacinthus sp.) IN ECOLOGICAL CONDITIONS OF SİİRT

Abstract

This study was carried out on the campus of Siirt University between 2016-2017 years. Solid worm fertilization (vermicompost) 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 plant growth and nutrient content of hyacinth (Hyacinthus orientalis L. "Purpe Star"). According to the results plant grwoth criteria, the highest mean on control treatment fırst flowering time 136,35 days; full flowering time 138,38 days, harvest time 140,92 days and the highest mean on V1; leaf number 5,710, leaf height 128,28 mm, floret diameter 28,140 mm, stalk thickness 13,507 mm; and the highest mean on V2; flower diameter 66,96 mm, and the highest mean on V3; flower height 116,33 mm and the highest mean on NP1; floret number 37,690 and the highest mean on NP2; floret height 26,768 mm, and the highest leaf diameter 28,86 mm and plant height 179,547 mm were obtained in NP3. 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 %, 0,291-0,603 %, 3,112-6,758 %, 802,333-1520,657 mg kg-1, 46,253-86,200 mg kg-1, 15,148-33,560 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 1,067-1,713 %, 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 7,39-18,556 mg kg-1 and Cu 4,711-6,949 mg kg-1 were determined.
