Understanding the associations among agronomic traits provides insight into their potential exploitation for yieldimprovement through agronomic and breeding interventions. The objective of thisresearch was to assess the association between grain yield and its contributingtraits using path coefficient analysis. The experiment was conducted in a randomised complete block design (RCBD) with three replications. Pearson correlation analysis showed a highly significant association between days to 50 % flowering and plant height (r = 0.85**). Path coefficient analysis revealed that plant height (0.113), number of pods/plant (0.400158), number of seeds/pod (0.041182), and 100-seed weight/plot (0.016093) had a positive direct effect on seed yield. Leaf area (-0.10851) and days to 50 % flowering (-0.21159) had a negative direct effect on seed yield. Among these traits, the number of pods/plant had the highest positive effect, while days to 50 % flowering had thehighest negative effect. The present study showed that characters including plant height and number of pods per plant need to be considered for indirect selection for improving seed yield for Bambara groundnut improvement.   El maní Bambara es un cultivo promisorio y subutilizado, con potencial para contribuir a la seguridad alimentaria. Comprender las asociaciones entre caracteres agronómicos permite su aprovechamiento para mejorar surendimiento. El objetivo de este estudio fue evaluar la asociación entre el rendimiento de grano y los caracteres que lo determinan mediante el análisis de coeficientes de sendero. El experimento se realizó en un diseño de bloques completos al azar con tres repeticiones. El análisis de correlación de Pearson mostró una asociación altamente significativa entre los días hasta el 50 % de floración y la altura de planta (r = 0,85**). El análisis de sendero reveló que la altura de planta (0,113), el número de vainas por planta (0,400158), el número de semillas por vaina (0,041182) y el peso de cien semillas por parcela (0,016093) tuvieron un efecto directo positivo sobre el rendimiento. El área foliar (-0,10851) y los días hasta el 50 % de floración (-0,21159) tuvieron un efecto directo negativo. El número de vainas por planta mostró el mayor efecto positivo, y los días hasta el 50 % de floración, el efecto negativo más alto. Estos caracteres deben considerarse para la selección indirecta en el mejoramiento del maní Bambara.
