Abstract: Allelopathy, the interaction of secondary metabolites produced by plants, microorganisms, viruses, and fungi, can have both beneficial and detrimental effects on agricultural and biological systems. Casuarina equisetifolia, a versatile tree species used in agroforestry, with allelopathy effects. The laboratory experiment was conducted to test the effect of allelopathy by Casuarina equisetifolia aqueous leaf extracts on the germination and growth of agricultural seeds i.e., Arachis hypogaea, Cicer arietinum, Vigna radiata and Zea mays to test for suitable agroforestry system. The aqueous leaf extracts of five concentrations as five treatments: T1(25%), T2 (50%), T3(75%), T4(100%), T5(Control) prepared were tested against germination percent, relative germination percent, growth and relative allelopathic effect on the chosen agricultural seeds. The results demonstrate a substantial negative impact on these agricultural crops as the concentration of Casuarina leaf extract increased. All the other crop treatments exhibited reduced germination rates, root lengths, shoot lengths, and dry weights, with the control group performing relatively well. These results suggest that the leaching of allelochemicals from the leaves into the assay had an inhibitory effect on both seed germination and growth.
