This work explores the potential toxicity of agricultural waste materials, specifically date palm seeds and palm fronds, on plant growth and health. These waste materials have shown promise as bioadsorbents for water purification, but their impact on plants needs to be understood. Toxicity assessments are crucial to ensure safe utilization and prevent negative effects on agricultural systems and ecosystems. Date palm seeds and palm fronds contain chemical compounds that can have allelopathic properties and influence neighboring plant growth. Experimental methods were employed to evaluate the phytotoxic effects of these materials, including germination assays and root growth inhibition tests. The results indicate that upon adsorption of PO4, palm leaves exhibited a significant enhancement in germination, leading to a remarkable increase of up to 371%. This outcome strongly emphasizes the effectiveness of palm leaves as vegetable fertilizers, highlighting their potential in agricultural applications. These findings contribute to understanding the phytotoxic potential of agricultural waste materials and developing sustainable utilization strategies.
