Abstract Boron (B) is a necessary micronutrient for higher plants and plays a part in germination and pollen tube growth. The purpose of this research was to determine the best levels of B spray on Tagetes flowers and to study the effects of these sprays on number of flower buds and flowers in short-stemmed Tagetes. A pot experiment in completely randomized design with 3 replications was conducted that included 4 B spray treatments (control: T0, 0.5 PPt: T1, 0.75 PPt: T2, and 1 PPt: T3). Results indicated that maximum number of flower buds belonged to the T3, followed by T2, and T1 treatments with 67.06, 63, and 43.71% increases in the number of flower buds, respectively, compared to the control. Moreover, B sprays at 1, 0.75, and 0.5 PPt yielded the largest number of flowers (1.55, 1.22, and 0.65, respectively). Therefore, B spray at 1 PPt yielded the best results in this research.
