The experiment of the present study was conducted in the winter season of 2024-2025 in one of the farms belonging to Al-Faris Agricultural Company in Safwan District/Basra, to determine the effect of some spraying treatments with Acadian seaweed extract to reconcile between two concentrations (0.5, 1) ml/L^-1 and different numbers of sprays (one spray, two sprays, three sprays) in addition to the control treatment (no spray). A Factorial Experiment was performed in seven treatments employing a totally randomized block design with three replicates in the greenhouse for hybrid eggplant plants (cv. Barcelona). The results showed that the plants sprayed with seaweed extract three times at 1 ml/L^-1 concentration significantly excelled over the control treatment in stem diameter, leaf area, number of fruits, fruit weight, single plant yield, early yield, and total yield (1.62 cm, 27.99 dm², 7.37 fruits, 305 g, 2.247 kg, 0.476 kg m^-2, 5.284 kg m^-2), respectively.
