DETERMINATION OF OPTIMUM PLANTING TIME FOR TUBEROSE [AGAVE AMICA (MEDIK.) THIEDE & GOVAERTS] UNDER THE HARRAN PLAIN CONDITIONS

The aim of the present work was to determine of optimum planting time and some agricultural charasteristics of tuberose [Agave amica (Medik.) Thiede & Govaerts] under southeastern Anatolian conditions of Turkiye. In the research, 7 planting times were tried with 15-day intervals, starting from 1 March to 1 June. The experiment was run in the summer growing sessions of 2022 and 2023 in Southeastern Anatolian conditions according to Randomized Complete Block Design with three replications. Results showed that statistically significant difference between planting times was noted at P<0.001 level. The following parameters including sprout duration (10-70 days), first flowering time (24 June-14 August), second flowering time (16-22 October), first flowering period (29-82 days), second flowering period (53-57 days) vegetation time (210–244 days), the plant height (29.90-43.10 cm), number of spikes per plant (1-2 number/plant), rootstock tuber circumference lenght (9.40-14.10 cm), number of new tubers (12.0-14.5) and new tuber circumference lenght (3.5-6.20 cm) will investigated. JMP-SAS software will use for statistical analyses. It was also seen that tuberose had a potential to adapt to Harran Plain ecological conditions. According to the results of this research, the highest datas were obtained from 15 April planting in southeastern Anatolian conditions.
