The study was\\\\\\\\r\\\\\\\\ncarried out at the Lath house located in the Department of Horticulture and\\\\\\\\r\\\\\\\\nLandscape Design, University of Kirkuk, Agricultural Research and Experiments\\\\\\\\r\\\\\\\\nStation, Al-Sayada. To assess the impact of two parameters, namely the foliar\\\\\\\\r\\\\\\\\napplication of Nano fertilizer with varying concentrations of macro and micro\\\\\\\\r\\\\\\\\ncomponents (0, 1.5, and 3) g, the study was conducted from October 23, 2022, to\\\\\\\\r\\\\\\\\nJune 4, 2023. The doses of L-1 and thiamine are 0mg, 150mg, and 300mg. The\\\\\\\\r\\\\\\\\nexperiment on growth and flowering attributes was planned using a randomized\\\\\\\\r\\\\\\\\ncomplete block design (RCBD). The findings were analyzed using the statistical\\\\\\\\r\\\\\\\\ntool SAS (2005). The Dunkin\\\\\\\\\\\\\\\' test was conducted at a significance level of\\\\\\\\r\\\\\\\\n0.05. The findings revealed that the application of Nano fertilizer, at a\\\\\\\\r\\\\\\\\nconcentration of 3 g. L-1, resulted in an increase in plant height by 18.6 cm.\\\\\\\\r\\\\\\\\nConversely, the use of thiamine led to a significant reduction in plant height\\\\\\\\r\\\\\\\\nwhen the concentration was increased to 300 mg. The length of L-1 is 14.16 cm. The\\\\\\\\r\\\\\\\\nstudy revealed that the combination between Nano fertilizer, which contains\\\\\\\\r\\\\\\\\nboth macro and micro components, and thiamine had a notable impact at a\\\\\\\\r\\\\\\\\nconcentration of 3 g. Concentrations of L-1 thiamine at 0.0 and 300 mg L-1\\\\\\\\r\\\\\\\\nresulted in significant increases in plant height (24.3 cm) and leaf area (1459\\\\\\\\r\\\\\\\\ncm2), respectively. Additionally, the plants exhibited an early blooming date\\\\\\\\r\\\\\\\\nat a dosage of 1.5 g. The treatment with L-1 and 300 mg L-1 (27.67) resulted in\\\\\\\\r\\\\\\\\na delay in blooming date (56.67) compared to the plant control.
