This research was conducted for the two seasons 2020-2021 and 2021-2022 in the orchards and nurseries development project located in Karbala Agriculture Directorate, Iraq. The field soil was ploughed followed by harrowing operations then it was divided into plots with an area of (2.5 m x 1.5 m) and each plot consisted of 8 lines, each line contanaing 10 plants.The lines of each experimental unit were divided into two parts besides the two guard lines, three lines were used for measurements of vegetative growth indicators, and the other three lines were used for measurements of seed yield and oil indicators. Three cultivars of rocket plant; (French, Turkish, and the local cultivar) were planted for two seasons aforementioned. The nano-NPK fertilizer was sprayed twice on the plant's vegetative part after the appearance of 3-4 true leaves, followed by the first spray of jasmonic acid after 20 days of planting, and the second spray of nano-NPK after 30 days of planting, followed by the second spray of jasmonic acid after 40 days of planting, i.e. the period between one spraying and another, was ten days. A third spray was applied to rocket plants after 60 days of planting. It started by spraying nano-NPK, followed by spraying jasmonic acid for ten days before the beginning of flowering (16) . The crop management was conducted as recommended like irrigation, hoeing, and weeding. The maximum and minimum temperatures, their averages, the number of hours of sunshine, and relative humidity were taken with the help of the General Authority for Meteorology and Seismic Monitoring/Meteorological Department in Karbala, Iraq.
