Abstract

The field experiment was carried out during the Winter/autumn cultivation season of (2021-2020) in one of the private fields in Fallujah city 60 km to the west of Baghdad at latitude 33° 19'53.6" north and longitude 43° 46'45.2" East to study the effect of foliar spraying with licorice extract and some nutrients on the growth and yield of red cabbage. A factor experiment with two factors was implemented according to the randomized complete blocks design (RCBD) with three replicates, the first factor is foliar licorice extract application in different concentrations. The second factor is the foliar spraying of nutrients The results showed that the effect of spraying with licorice extract and some nutrients led to a significant increase in (plant height, leaf area, total chlorophyll in the leaves, Leaf content of anthocyanin, curl percentage, head weight, total yield, nitrogen percent in the leaves, Phosphorous percent in leaves, potassium percent in leaves
