The study was conducted on a Teak Plantation established in phases between 2008 and 2012 to examine the impact of wildfire on weed seedling emergence and soil nutrients at Ilorin within the southern Guinea savanna of Nigeria. Soil samples were collected within three depths (0-10 cm, 11-20 cm and 21-30 cm) few days after the plantation was burnt by uncontrolled wildfire in 2016 and 2017. The weed seeds present were enumerated and soil properties analysed. Floristic weed survey was conducted on the teak plantation between May and November of each year. Results showed that Andropogon gayanus (18%), Tephrosia pedicellata (17%) and Senna obtusifolia (11%) were the most abundant weed species. Wildfire significantly (p<0.05) influenced weeds emergence. Twenty–five weed species were identified during the floristic weed survey. Twenty-two (22) % and 14 % of the identified weed species emerged on the burnt and unburnt field, respectively. Silt decreases while sand and clay fractions increased in the burn fields. Total N, organic C and available P increased in alternate years and depth of soil sampling. This result is valuable in aiding the prediction of likely weed infestations in a wildfire affected field, provide a valuable input in determining weed control strategy and soil nutrient managementFloristic survey, burning, bushfire, weed emergence, seed bank, soil propertiesArticle
