The effects of different planting times and vermicompost applications on the flowering of the hyacinth (hyacinthus orientalis "fondant") growing in the siirt ecological conditions

Abstract

In this study, Hyacinthus orientalis “Fondant” bulbs grown in Siirt ecological conditions were planted in 2016 at 15 days each between 14 November (1PT), 01 December (2PT) and 16 December (3PT). The study was carried out with 3 replications according to the “randomized block test design” in the experimental area of the Siirt University Faculty of Agriculture. Earthworm fertilizer (V) (vermicompost) were applied to the planting pits of the bulbs planted at different planting times with 100 g/bulb In addition, control plots (C) which are not fertilized were formed. In the course of phenological and morphological observations, as a result of interactions of planting time and fertilizer application, the lowest and the highest average values were obtained, respectively, between 101.923- 134.213 days for first flowering time (3PTxC-1PTxV), 103.103-135.766 days for a full flowering time (3PTxC- 1PTxV), 104.843-137.670 days for harvest time (3PTxC-1PTxV), 99.613-106.223 mm for flower height (2PTxV-1PTxV), 50.433-58.970 mm for flower width (2PTxC-3PTxV), 17.366-185.10 mm for floret length (1PTxV-2PTxV), 22.393-27.546 mm for floret width (1PTxC-3PTxC). Among these mean values, only the difference between mean length of floret was found to be statistically significant (p<0.01); when the planting times were taken into consideration, the difference between the average width of the flower (p<0.05) with all the flowering durations and the floret width (p<0.01) were statistically significant. The difference between the parameters of the planting time and the parameters of control and vermicompost applications were not statistically significant. As a result, the planting time interval for hyacinth plants was not determinative for the parameters examined. Regardless of the date of planting, bulbs were bloomed at approximately the same time. It is obvious that late planting time will be advantageous for irrigation and other maintenance.
