The study was conducted in a field located in Najaf province during the 2020-2021 growing season to test the quantitative and qualitative responses of red cabbage plants to the studied factors. The first factor was the foliar application of nano-treated organic fertilizer at three levels including 0.0, 1.5, and 3.0 ml.L-1, while the second factor was three levels of Jasmonic including acid 0, 15, and 30 mg.L-1.A factorial experiment following Randomized Complete Blocks Design (R.C.B.D) was adopted with three replications. Least Significant Difference Test (L.S.D) at a probability of 0.05 was used to compare among means. The results showed significant superiority of 3 ml.L-1nano-treated organic fertilizers on the quantitative and qualitative indicators by giving the highest rates of head diameter, height, weight, total yield, percentage of carbohydrates and fibers, nitrate content, anthocyanin pigment, and head compaction. Foliar application of 30 mg.L-1 Jasmonic acid was significantly superior over all other concentrations by giving the highest mentioned indicators.The interaction between of 3 ml.L-1nano-treated organic fertilizer and 30 mg.L-1 Jasmonic acid showed significant superiority over other treatments regarding studied indicators.This interaction treatments scored 18.35 cm head diameter, 15.62 cm head height, 1570 g head weight, 40.33 tons.ha-1 total yield, 4.30% and 10.22% the percentage of carbohydrates and fibers, 0.357 mg.g-1DW nitrate content of the heads, and 24.65 mg.100 g-1FW anthocyanin pigment, and 12.08 kg.cm-2 head compaction over control treatment which recorded the lowest value of 14.39 cm, 11.95 cm, 993 cm, 25.87 tons.hectares-1, 2.81%, 5.23%, 0.629 mg.gm-1DW, 15.34 mg.100 g-1FW, and 10.90 kg.cm-2 respectively.
