The experiment was done in the Lath house of the College of Agriculture/ University of Mosul for a period from March to 15 October during the season 2019 on Tagetes patula. The experiment was carried out using three factors within R.C.B.D design. This experiment was laid out in order to study the effect of nano NPK (12-12-36), Fylloton extract and salicylic acid on the growth of plants, flowers, essential oil compounds during the growing seasons of 2019. The treatment was nano NPK (0, 30, 50, 65) mg.pot−1. Fylloton extract (0, 2) ml.L−1 and salicylic acid (0, 120) ml.L−1. Results showed that these factors had a significant effect on all traits of Tagetes and recorded the highest plant height, number of branches, herb fresh and dry weight, days to first floret opening, flowering time, number of flowers and diameter flowers as well as the active essential oils (Camphor, Sabinene, Terpinene, Linalool, α-Pinene, Tagetone and Nerol) had been increased in the interaction nano2 or nano3 with Fylloton and Salicylic acid. The nano3 a lone (65 mg.pot-1) had been recorded the maximum percentage of active substances (Camphor, Myrcene, Limonene) which reached (7.6, 5.78, 6.29)% respectively.
