Abstract: The study examined the characteristics of Indigenous Knowledge Systems (IKS) influencing their utilization by rice farmers in Ekiti state of Nigeria. Two hundred and sixty-six rice farmers were selected through a multi-stage random sampling technique and data procured through the administration of a validated and structured interview schedule. Results obtained through correlation analysis revealed a positive association between IKS utilization and Affordability (r = 0.17, p≤0.05), Effectiveness (r = 0.08, p≤0.05), Communicability (r = 0.677, p≤0.01), Relative advantage (r = 0.368, p≤0.01) and Availability (r = 0.054, p≤0.01). However, a negative association was found between IKS utilization and Environmental-friendliness (r = -0.351, p≤0.01).
