The cashew tree, Anacardium occidentale, is a tough, drought-resistant tropical and subtropical tree. Pigeon pea (Cajanus cajan) is one of the most significant legumes in semi-arid tropical areas. The researchers looked at the effects of cashew leaf and stem bark extracts on pigeon pea seed germination. It took place in the Department of Plant Science and Biotechnology's laboratory at Michael Okpara University of Agriculture in Umudike, Nigeria. The experiments were carried out in Petri dishes filled with cotton wool that had been sterilised. The seeds were given various concentrations of aqueous extracts of cashew leaves and stem bark, namely 30 percent, 50 percent, and 70 percent, with distilled water serving as a control (0 percent). As the quantities of the aqueous extracts of both the cashew leaves and stem bark rose, they had a substantial (p 0.05) inhibitory effect on the germination percentage and rate of C. cajan. The cashew leaf extracts had the highest value of 70% (80.00%), whereas the control had the lowest value (96.66 percent ). Furthermore, the cashew stem bark extracts had the highest value at 70% (86.66%), while the lowest value was at control (96.00 percent ). The phytochemicals present in the tissues of A. occidentale had a considerable phytotoxic effect on the germination of C. cajan seeds, according to these findings.
