Determining the effects of organic fertilizer and foliar application of mallow leaf extract on the growth and yield of eggplant was the aim of this latest study held in spring 2021 in the Al-Najaf Province, Iraq. The treatments comprising adding decomposed palm waste to the soil at three levels (0, 16, and 32 mg ha^-1), foliar application of mallow leaf extract at three concentrations (0, 0.2, and 0.4 gm.l^-1), and their interactions incurred probing in eggplants. The experiment began in a randomized complete blocks design (RCBD) with factorial arrangement and three replications. The results obtained through the analysis of variance continued to further evaluation through the least significant difference test to compare and separate the various means. The results showed that organic fertilization with decomposing palm residues at 32 mg ha^-1 significantly outperformed the other treatments for plant height, total leaves, dry weight of vegetative growth, fruits per plant, yield per plant, total yield, nitrogen (%), and total chlorophyll content in the leaves.

Key findings: Organic fertilization with decomposing palm residues (32 mg ha^-1) outperformed the other treatments for plant height, number of leaves, dry weight of vegetative growth, fruits per plant, yield per plant, total yield, nitrogen (%), and total chlorophyll content in the leaves.
